Do-it-yourself walk-behind tractor made from a friendship chainsaw: drawings, instructions

Self-production of a walk-behind tractor from a Ural chainsaw

The procedure for assembling a walk-behind tractor with an engine from the Urals is no different from the instructions presented above.
Differences may occur due to the design chosen, but are generally minor. Be sure to test the equipment after assembly, using extreme caution. Do not forget to install the weighting material in the front part of the walk-behind tractor, securely fixing it to the body

If the part is not secured securely, the cultivator will begin to vibrate during operation, which will lead to engine damage.

It is advisable to assemble the structure under the supervision of an experienced specialist who is well versed in technology. Assembling homemade equipment for the first time, without experience in this field, is fraught with unpredictable consequences. At best, you will simply ruin the saw, and at worst, your health will suffer. Remember that compliance with safety precautions and care when performing all stages of assembly is the key to stable operation of the device. If possible, purchase a normal walk-behind tractor, and use a homemade machine in extreme cases.

What homemade chainsaw products have already been invented?

The first use of a chainsaw from the point of view of many developers is to cut logs into beams with its help. But, if you hold the chainsaw suspended manually, the cutting accuracy suffers, especially when the beam is four to six meters long. To prevent the cut from moving away from the desired line, we came up with the idea of rigidly securing the chainsaw in a frame that moves along guides.

In such a sawmill, the log lies motionless, and the carriage with the chainsaw is located at the required height, depending on the desired thickness of the beam, and is fixed with four screws.

Thanks to the precise movement of the frame, a smooth and neat cut is obtained. You can cut boards in the same way, but due to the large thickness of the cutting chain you will end up with a lot of waste.

Chainsaws "Friendship"

The legendary Druzhba chainsaws come from the USSR. Nowadays, they are no longer produced, but they can be found in the garages of our fathers and grandfathers and, surprisingly, are still in working order. The year of production of the first petrol saw “Druzhba” was 1955. Development began two years earlier. On the territory of the USSR, two machine-building plants were engaged in the production of these chain saws: Perm and Biysk. The developers were constantly improving things and introducing new technologies.

These changes can be observed in chronological order:

1953 - the beginning of the development of the first chain saw “Druzhba”.
1955 - the first chainsaws “Druzhba-2” (the saw handles are attached directly to the fan) and “Druzhba-4” (the handles are attached to the clamp connecting the motor and the saw gearbox) came off the assembly line; serial production of chain saws was launched.
1958 - victory at the international exhibition in Brussels, after which chain saws began to be supplied abroad.
60-80s - production of the modernized Druzhba 4-A chainsaw, a chain lubrication system, magneto and KMP-100 carburetor appeared.
1990 - modernization of the Druzhba 4A chainsaw, release of the improved Druzhba-4A-Electron model. In this model, electronic ignition was installed for the first time and a new KMP-100U carburetor was installed.

Features of the walk-behind tractor

Structurally, a homemade walk-behind tractor is a two-wheeled unit on a frame, producing up to 4 liters. s at an average speed of 2.5-2.7 km/h. Features, as well as operational tasks, are largely determined by the choice of power plant. If we are talking about a conversion from “Friendship”, the following parameters will distinguish it from a purchased walk-behind tractor:

small size, lightness;
savings on fuel and lubricants;
the ability to assemble a unit tailored for specific work (required frame size, mounting unit).

A homemade walk-behind tractor can plow, hill up crops, harrow, mow or remove tops, and apply fertilizer. Due to its small size, it can be used in hard-to-reach places (for rocky, poor soil, the power of a homemade product may not be enough). It will be especially useful for those in whose area the strength and power of a large purchased walk-behind tractor will be excessive.

Step-by-step instructions for making a walk-behind tractor from “Friendship”

The manufacturing process depends on the chosen design option and drawing. Step-by-step analysis of one of the modifications:

Two bases (spars) are made from a steel pipe or profile with a diameter of at least 20 mm. The bend is made so that the ends are bent upward.
On the long part, a steering wheel is welded, either welded at random or taken from a motorcycle. The bases are connected and reinforced by cross members. Also, platforms for the battery and gas tank are welded or screwed to the bend of the base.
To mount the engine, a structure in the form of a slide is made from pipes or profiles. The motor is attached to it, and then to the base.
Next, the RU-32 collar flange from the VAZ car is installed. Thanks to it, the shaft transmitting forces from the motor will be fixed. It is also recommended to use a VAZ gearbox shaft as a shaft. To fix the shaft in the flange, bearings with a diameter of 30 mm are used.
The transmission link is made from sprockets from any old car or moped. One is mounted on the gearbox shaft, the other on the shaft on which the cutters or wheels are located. A chain from an old motorcycle is connected to each other.
Next, all parts are installed and connected.
You can also make wheels and cutters yourself, using old wheels from a car or agricultural machinery as a base. The resulting parts are mounted on a steel pipe or circle of the required diameter.

You also need to consider an effective forced-type cooling system. Several options are offered. The simplest option is to install a fan. More complex designs offer the use of water cooling.

Required tools and materials

To make a walk-behind tractor from a Druzhba chainsaw, you need to prepare the following parts and materials:

from the Druzhba chainsaw - engine, fuel tank, gearbox;
steel pipes, angles or profiles for assembling the base of the structure;
iron sheets to strengthen and protect the structure;
steering, suitable for a motorcycle or moped;
wheels from a motorcycle or any other small diameter;
transmission, can be used from a car or moped;
fasteners - bolts, nuts, washers.

As a tool for work you will need:

electric welding;
angle grinder (“grinder”);
spanners;
drill, drill bits;
marking tools (tape measure, square, etc.).

The steering can be used ready-made or, if necessary, made independently from steel pipes. Welding can be used as fasteners; if it is not available, parts can be secured using a bolted connection.

Features of creating a cultivator from a Druzhba chainsaw

A DIY chainsaw cultivator “Druzhba” will become an indispensable assistant when cultivating soil in small areas. The big advantage of this method will be the absence of the need to resort to turning work - you can limit yourself to spot metalwork modifications. Future homemade chainsaw motor cultivators will operate in only two gears, and the maximum speed of the units will reach 2.5 km/h. The engine power will be a little more than 4 liters. With. Such indicators will be quite sufficient for effective soil milling, hilling and digging up potatoes.

The creation of an aggregate is performed according to the following algorithm:

To begin, place a metal collar flange RU-32 on the main shaft;
After this, screw on the axle gear sprocket;
Next, attach the shaft of the bridge gearbox - the part can be taken from a UAZ car and polished to a diameter of 3 cm;
To increase the distance between the gearbox axle and the ground, use a double-row chain and two “VAZ” sprockets - they will increase the cultivator’s ground clearance to 150 mm;
Next, install and secure the housing bearing on the main axle - its internal diameter should be no more than 3 cm;
The engine from the Karpaty moped can serve as a gearbox and gearbox;
To complete the configuration, take a centrifugal clutch from the same moped;
To install the cutters and wheels, use a steel pipe 32 cm long.

Thanks to a completely sealed fuel supply system and a membrane-type carburetor, the owner will be able to work with the unit in any conditions, be it heavy rain or unbearable heat. The manufactured structure can be successfully used in areas with a total area of 10 to 20 acres.

Description of a walk-behind tractor with a chainsaw engine

So, we have a chainsaw that is not used very often or is completely lying around. In this case, having made some calculations and prepared the necessary materials, our saw turns into an excellent walk-behind tractor. The principle of assembling homemade agricultural machinery, depending on the brand of the manufacturer, may vary, but the general principles are as follows:

The most important step is the preparation of a drawing, guided by which you will assemble the required structure. You can create drawings and diagrams of a walk-behind tractor using a chainsaw yourself, or by downloading ready-made calculations from the Internet. Finding them will not be difficult, just enter a query into a search engine and select the assembly option you like.
The drawings have been found, which means it’s time to assemble the frame for our motor cultivator.
Once the frame is ready, the saw motor and its gas tank are attached to it.
Lastly, additional system elements are installed that are responsible for controllability and other functionality.

Note! Not only a chainsaw motor is suitable as a motor, but also an engine removed from a motorcycle or moped. In this video we’ll look at the friendship chainsaw motor cultivator:

In this video we’ll look at the friendship chainsaw motor cultivator:

To implement the idea, prepare the following materials:

Motor from any existing chainsaw. The Druzhba and Ural saws are best suited for this.
A handlebar removed from a moped or motorcycle.
Welding machine.
Pipes and sheets of metal, in the quantity necessary to assemble the walk-behind tractor frame.
Wheels from non-working equipment.
Transmission.

Having prepared all the structural elements and assembled them in accordance with the drawing, you will receive a device with the following characteristics:

Powerful. Some homemade designs have a power of 9 horsepower.
Lung.
Small-sized.
The motors used in chainsaws have a large margin of safety, which allows you to work on a homemade installation for a long time.
Economical.

As an example for assembly, we will consider 2 engine options taken from Druzhba and Ural chainsaws. They are considered the most suitable for our venture, and here's why.

Friendship

Chainsaw Friendship has the following characteristics:

Motor with a power of 3.5 horsepower.
Weight – 7 kilograms.
The volume of the gas tank is 0.55 liters.
The volume of the oil tank is 0.26 liters.

For assembly, it is recommended to use the 4th generation Friendship model.

Products manufactured under the Ural brand have different characteristics from Druzhba. The differences are in the following details:

The power of the Urals is higher than that of Friendship, and is 5 horsepower.
The engine produces a lot of soot during operation.
The gearbox installed on the saw tends to jam from time to time.
Small specks, getting into the Ural saw engine, burn out without causing any special damage to it.

As you can see, each model has its pros and cons. It’s up to you to make a walk-behind tractor from a Ural chainsaw motor or construct a homemade walk-behind tractor from parts of a Friendship chainsaw.

snow blower

If in the previous design you replace the shaft with plowshares or harrow spokes with an auger mechanism, add a casing, an intake device and a pipe for throwing out snow, the cultivator will turn out to be quite a decent snow blower. Many home craftsmen design their homemade products with replaceable attachments for different seasons. Motor from a Shtil saw with a power of 3-5 hp. It will cope quite well with cultivating the garden in spring and autumn, and with removing loose snow from a summer cottage in winter. The most important unit is the screw mechanism.

Homemade snow blower

If you are not a professional designer, then it is better to download ready-made drawings from the Internet. The auger blades are made of thick rubber, for example, from a conveyor belt. The intake device is made of galvanized steel. A plastic sewer pipe is suitable for the snow disposal pipe.

DIY chainsaw snow blower

A snowplow with a factory-made chainsaw engine is a budget option for assembling high-quality, passable and fairly maneuverable equipment. A chainsaw snow blower has much smaller dimensions than store-bought equipment, so it can cope with snow removal in the most difficult to reach places.

Before you begin, you will need to select drawings. The diagram used must accurately indicate the dimensions of all components, and must also be capable of installing them into a common device.

To assemble the homemade product, you will also need to prepare parts. Their list includes:

pipes of different diameters made of steel and aluminum;
forged metal shaft;
several bearings;
Sheet steel;
welding machine;
hand tools: wrenches, screwdrivers.

Assembling a homemade household snow blower from a chainsaw consists of several stages. Their list includes:

Frame assembly and engine installation. A homemade snow blower must be equipped with a durable and impact-resistant frame. The stability of the snowplow when moving off-road, as well as the protection of its internal parts from mechanical damage, largely depends on its quality and balancing.

It is best to weld a durable frame from solid steel and aluminum pipes. The base of the frame should be assembled from pipes of the same diameter. Next, pipes of smaller thickness will be welded to them.

During assembly, you need to pay attention to the 2 installed longitudinal pipes, which in the device will not only play the role of one of the parts of the frame, but also perform the function of snowplow skids. When connecting, all their holes will need to be welded so that snow does not clog in them, causing corrosion.

2. Assembling the housing of the working auger and the drive mechanism of the snow blower. To create a working auger, a pipe of small diameter, 80–85 cm long, is best suited. On an auger of shorter length, it will be difficult to install a reliable drive located in front of the main part of the later-made bucket. One of the main roles when making an auger yourself is played by correctly selected bearings for the shaft.

3. Making a snow blower bucket. To assemble the bucket yourself, you will need 2 round metal sides, the initial size of which should initially exceed the immediate dimensions of the auger by about 7 cm.

Before you finally secure the auger for the snow blower, you will need to put bearings on the shaft;

4. Assembling the ejection chute. To make this part of a snow blower from a household chainsaw, you will need an aluminum pipe, at least 10 cm long and about 15 cm in diameter. To install the aluminum pipe, you will need to make several holes in a homemade auger. Next, a solid metal pipe is inserted into them and secured with bolts.

5. Final assembly of a snow blower with an internal combustion engine from a chainsaw. To assemble a homemade product, first of all, you need to weld a bucket and auger to the longitudinal parts of the manufactured frame. Next, you will need to install a chain on the manufactured drive. To make this easier, you need to use a tension sprocket, which will be attached to the auger with bolts.

Next you will need to make a handle using several metal pipes. You will need to display the controls on it: the throttle position adjustment lever, the ignition on and off button, as well as other switches.

A snow blower assembled in this way from a household chainsaw will be able to clear areas ranging from 5 to 25 acres. The homemade product will be quite easy to maintain and suitable for independent repair.

What else can you do

There are many options for possible homemade products. It all depends on the imagination and skills of the craftsman. In addition to what is described, you can make from a chainsaw:

a generator that will provide electricity to a cottage far from communications, a comfortable outdoor recreation;
a grinder capable of cutting metal, stone, concrete, and polishing surfaces;
a winch that makes life easier for motorists who like to drive off-road;
cultivator for processing the garden, harvesting.

The list includes motorized drills for making holes in the ground for poles and planting trees. Its winter variety is an ice drill for winter fishing.

Step-by-step instructions for making a snowmobile from a Druzhba chainsaw

As has already been said many times, the manufacturing process depends on the chosen design option and drawing. There are complex schemes, but there is one fairly simple option using a regular snow scooter as the basis for the design. It is captivating because it already has a ready-made supporting base, steering and a completely comfortable seat. The task is to strengthen the side skis, as well as mount the engine, transmission and track to the frame.

Step-by-step assembly instructions:

First of all, it is necessary to strengthen the side skis. This can be done by welding a profile or pipes to them. The support bearings of the front and rear tension shafts are also attached to them. The size of the reinforcing base depends on the diameter of the front shaft. For best grip, the bottom of the shaft should be level with the skis.
The next stage is the manufacture of the track mounting frame. It is made from a corner and a profile pipe measuring 30x30 mm. The length of the frame is taken to calculate the dimensions of the frame for mounting the engine with a gas tank in the rear of the snow scooter. The width is within the width of the snow scooter.
The track is tensioned using shafts. It works on the principle of tensioning the chain in a chainsaw. The tension shaft is moved by a bolt, which in turn is fixed to the frame. As tension shafts, you can use tubeless wheels from hand trucks, rollers from agricultural machinery, or make them by hand cutting them out of plastic. It is also necessary to install support rollers for the caterpillar, only without a tensioning mechanism. They are made in the same way as tension ones. To ensure the required clearance and prevent the rollers from moving, insert bushings are installed on the axle.
The caterpillar is made of a conveyor belt with a thickness of at least 3 mm. Gear wheels from the Buran snowmobile are mounted on the tension shafts in the center. The tape is cut into two parts and placed along the edges. Between the pieces there is a distance commensurate with the width of the gears. Hitch tracks can be made from halves of a plastic water pipe or an aluminum profile. The thickness of the tracks is recommended to be more than 5 mm. The tracks are fastened with bolts or rivets. The gap between the tracks should correspond to the pitch of the gear wheels from the Buran.
A platform with an engine is still mounted on the back of the snow scooter. A gas tank is also installed on it. A drive sprocket is mounted on the drive shaft, and a sprocket is also mounted on the engine. The power transmission is carried out by the drive chain. To ensure chain tension, the frame with the engine must be movable, the sprockets must be at the same level.
After securing the main parts to ensure safety during operation, the moving parts of the snowmobile are covered with protective covers made of metal or plastic.

Walk-behind tractor from a chainsaw - manufacturing, drawing, instructions

The simplest and easiest option for creating a homemade walk-behind tractor is to remake it from a chainsaw. Any model you have at home can be suitable for these purposes. Thanks to the powerful motor, lightweight design and high performance, such homemade ones are well suited for effective cultivation of the land on the site.

How to make a walk-behind tractor from a chainsaw with your own hands?

To create such a homemade unit, it is recommended to use special drawings. You can draw these diagrams yourself if you have some knowledge and idea about the walk-behind tractor, or you can choose one of the proposed options

A homemade walk-behind tractor from a chainsaw is created in several stages, and it is important to follow all the nuances indicated in the diagram

Making the frame. To do this, use a thick-walled pipe, from which you should create a cube with corners of 32x32mm.
Installing the motor on the upper frame corners of the frame, which are transverse. You also need to attach the fuel tank using brackets (the tank must be placed below the engine).
The frame on the front part is equipped with vertical posts, which serve as intermediate shaft supports.
Special supports are attached to the longitudinal corners, which will then allow the installation of running shaft bearings.
A metal weight is installed on the front element of the frame, which will ensure the stability of the walk-behind tractor.
Handles for control are constructed from small metal pipes.
The walk-behind tractor is equipped with old small wheels, and can also be made from metal plates.

As a result, you can get a good walk-behind tractor, whose center of gravity is located above the wheel support surface.

Creating a walk-behind tractor from a Druzhba chainsaw

The Druzhba chainsaw is considered the best choice for making a walk-behind tractor. This simple and very productive technique is probably in the arsenal of many owners. Using its structural elements, you can make a fairly powerful walk-behind tractor, as it has the following features:

Due to its low weight, such equipment can be used for work of any complexity.
Very productive engine.
Compact and durable.

Based on this device, a high-quality walk-behind tractor is obtained, the speed of which is 2.5 km/h and the power is about 4 hp.

The process of creating a unit is similar to the method that is used for all other models, but it also has its own nuances:

The main shaft of the future design is equipped with a special flange, which is of the collar type, RU-32, which will then make it possible to easily screw on bridge type gearboxes.
Sprockets are taken from the UAZ and, together with a double-row chain, are installed on the future device and allow you to increase the distance from the gear axle to the ground. Timing sprockets allow you to increase the distance to the soil by 15 cm.
The housing type bearings are screwed to the main axle and their diameter is 30 mm.
The gearbox with gearbox can be constructed from the motor from the Karpaty motorcycle; it is necessary to provide a standard centrifugal clutch.
To install the cutters and then install the wheels, you need to use steel pipe.

You need to install a load in front of the frame that can hold the center of gravity.

A pipe with a diameter of 30 mm is welded as handles.

As soon as the chainsaw walk-behind tractor is ready, it can be tested on the site. To do this, fill up with fuel and try to complete the work. Modify your device if necessary.

The advantages of such a unit are:

the ability to use a variety of lubricants and combustible materials;
work in completely autonomous mode;
suitability for any type of work.

To create this type of technique from a chainsaw, you do not need specific knowledge. All it takes is a little ingenuity and the desire to get an effective technique. A homemade walk-behind tractor suitable for use on private plots and dachas. sadovaja-tehnika.com

What homemade products can you make from a chainsaw?

A chainsaw is a very convenient tool for making homemade items. By adapting it to a special platform with wheels and connecting the chain to the shaft on which the blades will be installed, you can get a powerful lawn mower. By the way, in order not to bother for a long time, you can install a sprocket from the rear wheel of a bicycle on the shaft.

In addition, a chainsaw can be used to make an excellent sawmill, since reworking this tool, in this case, is also reduced to a minimum.

In general, all homemade chainsaws can be divided into two large groups:

The first group includes those homemade products, in the manufacture of which there is practically no need to disassemble and modernize the chainsaw;
The second group of homemade products includes all kinds of equipment: snowblowers, mopeds, snowmobiles, ATVs, etc. In other words, complex mechanical devices, for the manufacture of which you will have to radically disassemble the chainsaw, make a water or air cooling system, in general, completely change this petrol tool.

Let's look at what can be made from a chainsaw, which will definitely come in handy in the household.

So, for example, based on the Druzhba chainsaw you can make the following homemade products:

Powerful boat engine;
Gasoline grinder;
Sawmill;
Motor cultivator;
Lawnmower.

When it comes to car homemade products, then from almost any chainsaw you can make:

Moped, if you install a chainsaw on a bicycle;
Snowmobile and snowmobile;
Snow blower;
Quad bike;
Scooter.

Of course, the second group of homemade chainsaws requires a thorough approach and a complete study of the design.

Also, you will need to purchase all the necessary materials, and in some cases, you cannot do without a welding machine.

Chainsaw sawmill

The easiest to make is a homemade sawmill from a Ural, Taiga or Druzhba chainsaw. The essence of how a homemade sawmill works is that there is one large guide along which the chainsaw moves back and forth on a movable sled.

As a guide, you can use a rail or several long but even metal corners. The platform on which the chainsaw will subsequently be attached is made of a piece of thick steel, the thickness of which must be at least 5 mm.

The moving part of the sawmill deserves special attention, the one through which the platform moves along the guide. Here you can use a metal pipe with a rubberized surface as rollers

It is very important that the width of the moving part matches the width of the guide

As you can see in the photo, a log located next to the sawmill is quite easily cut into several parts using a chainsaw moving along a guide. Thus, you can save a lot on the purchase of a sawmill, and, as you can see, the chainsaw practically does not need to be altered, disassembled, etc. in any way.

Walk-behind tractor from a chainsaw

As mentioned above, you can use a chainsaw to make various homemade products for your home and garden. Some of these homemade products are a mower and a walk-behind tractor. With a mower made from a chainsaw, things are not as difficult as with a walk-behind tractor, for the manufacture of which you will have to weld a metal frame, and then fit two wheels on the side to it.

The principle of making a walk-behind tractor from a chainsaw is to use several sprockets that could transmit rotating force to the knives. For these purposes, the sprockets are located on the sides of a metal shaft on which several knives are welded.

A homemade walk-behind tractor from a Ural or Druzhba chainsaw will become a real helper for those who have a fairly large garden. Perhaps such a walk-behind tractor will not be very powerful, but it will be quite enough to solve the main task of cultivating the land.

Do-it-yourself walk-behind tractor from a chainsaw

A chainsaw is a device that is most popular among craftsmen. It can be used as a kind of universal drive in order to produce a walk-behind tractor with your own hands. This instrument perfectly combines important qualities:

1. Quite solid power;

3. Maximum compact dimensions.

Using a chainsaw, you can create and assemble winches, bicycles and other objects.

A chainsaw allows you to make a wide variety of interesting designs with your own hands. For general activities, you will need knowledge of drawing, design, and so on. These skills are important for subsequent high-quality assembly, obtaining accurate dimensions and simply for a normalized work process.

How to make a walk-behind tractor from a chainsaw with your own hands: several design options

A walk-behind tractor based on a chainsaw can be recreated using different methods:

universal, designed for any type of powerful chainsaw;
specific, applicable to a specific modification, for example, “Friendship” or “Ural” of the Soviet or modern type.

Walk-behind tractor from a chainsaw: the easiest and most universal way

For it we will need:

motor base from any productive professional chainsaw;
steering wheel (motorcycle steering wheel will do);
a transmission that can be removed from an old car or moped;
electric welding;
stainless steel pipes;
metal sheet for designing lugs or old wheels from used equipment;
connecting parts that will be needed to fasten the frame and engine.

The home production process can be divided into several stages:

drawing up a detailed drawing. If it is missing, you can use the one we offer;

Read also: Blackening stainless steel at home

frame production;
modification of the power plant;
design and assembly of additional units - clutch, gearbox, steering, headlights for night work, chassis.

Making a frame for a walk-behind tractor from a chainsaw

The work process looks like this:

we take a metal pipe with a cross-section of at least 20 mm and bend it so that the overall appearance resembles 2 spars, the edge of which is directed upward;
We weld the steering wheel in the rear part of the spar;
we strengthen the base with crossbars;
We weld a support platform for the battery to the rear bends of the side members.

Assembly of the motor block

For a homemade walk-behind tractor from a chainsaw, it is ideal if the motor power is in the range of 10-13 hp.

The creation of a power plant in the presence of a ready-made, serviceable engine is carried out as follows:

Take a pipe 7 cm in diameter, from which 250 mm is cut with a grinder - it will become the future muffler. It is filled with wood waste and diverted so that the exhaust is directed away from the operator. Ensure that the exit circumference does not exceed 1.6 cm in diameter;
A frame made in the form of a slide is adapted from a stainless steel pipe with a cross-section of about 4 cm. To secure bolt ties, we weld metal brackets to its periphery and middle part;
We connect the engine and the frame structure.

After that we move on to the chassis.

The most popular ways to recreate it are:

the use of old Zhiguli tires (all 4 pieces), which are connected in pairs by axle shafts reinforced with a cotter pin;
assembly of lugs based on tires without rubber (drawing below). For better adhesion to the soil, they are retrofitted with a metal corner.

After installing the transmission, steering wheel, and gas tank on the homemade product, the unit can be tested in the field.

Procedure

Once a suitable drawing (component layout diagram) has been selected, the necessary tools have been found and the Druzhba saw has been dismantled, you can begin assembly. You should start with the frame, since all the elements of the motor unit will be attached to it. The process is completed by assembling the chassis, as well as additional blocks: if desired, headlights, gearbox and clutch, if the drawing is more complex and requires them. For the first time, it is best to choose a simpler drawing.

Frame assembly

The first stage involves the following actions:

bend the pipe so that it takes the shape of 2 spars with edges pointing upward;
the steering wheel is welded at the back (the easiest way is to weld two handles, but if available, you can use a ready-made steering wheel from a motorcycle);
It is recommended to strengthen the structure with cross members from the same pipe;
We cut out a “shelf” from a metal sheet for the battery, which we weld to the rear bends of the side members.

It turns out to be a vague resemblance to a sleigh. For heavier structures with more powerful power units, the frame can be made in the shape of a cube or similar to a tractor for 4-wheeled homemade products.

Assembly of the motor block

The most difficult stage is assembling the components. Before you begin, you need to mark on the frame the places to which the parts will be attached. The principle is as follows:

a motor with a gearbox is mounted on top of the crossbars;
a fuel tank is installed under the engine (a separate support should be welded under it), the battery is mounted on a special platform;
To prevent exhaust gases from entering the control unit, you can make an exhaust pipe from a 7 cm metal tube with a diameter of up to 25 cm.

This is the basic version without a gearbox, which can be installed upon request. The drawings will help you understand the assembly in more detail. By and large, the details of “Friendship” are simply rearranged. The hitch is connected to the output shaft of the chainsaw.

Chassis assembly

There are at least two options: you can use a ready-made axle shaft from a car, or you can make a homemade walk-behind tractor driven by physical force (the “chassis” of an old cart or wheelbarrow will come in handy, which will significantly reduce the weight and dimensions, because a car axle shaft will require the use of tires). In the first case, you will have to organize the drive from the motor to the axle shaft, which is not easy, so welding the “running” wheelbarrow to the frame is a more understandable option.

It is not difficult to figure out how to make a walk-behind tractor from a chainsaw if you understand the general operating principle of both units. In addition to “Friendship”, “Ural” and “Taiga” saws are also suitable for the walk-behind tractor. When deciding to experiment, you should understand that the homemade product will have limited functionality and low power, allowing you to process a maximum of 20 acres.

The walk-behind tractor is an effective assistant in the processes of cultivating the land, as well as further caring for the garden and garden. The easiest way to obtain this device is, of course, to purchase it. However, there is an option for making it using a chainsaw engine, in particular from the Soviet “Druzhba”. Its powerful engine, simple design and overall unpretentiousness make it well suited for this role.

Peculiarities

Before you start producing a motor cultivator, you should decide what type of agricultural unit you will design: with an electric motor or with an internal combustion engine.

It is important to remember the fact that a motor cultivator with an electric motor will only be effective if there is an energy supply system in the area that is planned to be processed. On the contrary, a device incorporating an internal combustion engine can be used in the field, since it runs on fuel, namely gasoline

Another important nuance is the method of tillage. There are cultivators that have driven wheels, as well as those units that are equipped with mounted tools (the latter can serve not only as walk-behind tractors, but also as vehicles).

What elements are needed for assembly?

If you decide to design a walk-behind tractor yourself, then you need to prepare the following set of components:

motor or internal combustion engine;
gearbox - it is able to reduce speed and increase forces on the working shaft;
frame on which the equipment is mounted;
handles for control.

These are the main parts - without them it is impossible to make a machine for agricultural cultivation at home. Therefore, before starting the manufacturing process, make sure that each of the elements described above is present.

A homemade moped made from a chainsaw is unlikely to compare with the industrial version of the device, but it is quite suitable as a kind of adult toy. By and large, the device is not a moped, but a bicycle with a chainsaw engine. This is due to the fact that most often it is the old frame from this vehicle that is used.

A moped using a chainsaw can accelerate to 30 km/h. Note! More advanced craftsmen do not take a ready-made frame from an old bicycle, but independently make a welded structure for this purpose from metal pipes or a square profile. But the main components, including bearings, prefer to use factory ones.

Before installing a chainsaw engine on a bicycle, you should ensure that you have parts, such as:

frame;
engine with gas tank;
gearbox with gear ratio 18:1;
shock absorbers;
brakes

Any engine for a bicycle from a chainsaw must be supplemented with a gearbox so that it is possible to regulate the rotation of the wheels. Sometimes, instead of a gearbox, gear pairs are used, connected to each other by a chain from a bicycle. If we take a mountain bike as a basis, then a gearbox with a gear ratio of 1:15 or 1:20, supplemented by a variator, is more suitable here. The main advantage of a mountain bike with a chainsaw motor is that, unlike a conventional device, it can be accelerated to 30 km/h.

Another simple vehicle to use is a chainsaw kart, which resembles a simplified model of a car, which is used mainly for circuit racing. The device does not have a solid body and does not have shock absorbers. The minimum number of parts makes it possible to lighten the design and provide it with greater speed of movement.

For a bicycle you need not only a chainsaw engine, but also a gearbox.

The frame is most often welded independently from a metal profile, and old carts are used as a wheel donor. A bicycle chain is used as a drive for the rear axle, and you will also need a steering linkage. To assemble the housing, you will need to use a welding machine. Some people consider a home-made kart to be a children's car with a gasoline engine, but you need to keep in mind that the vehicle is capable of developing a decent speed.

Creating a walk-behind tractor from a Druzhba chainsaw

Due to its low weight, such equipment can be used for work of any complexity.
Very productive engine.
Compact and durable.

Based on this device, a high-quality walk-behind tractor is obtained, the speed of which is 2.5 km/h and the power is about 4 hp.

The process of creating a unit is similar to the method that is used for all other models, but it also has its own nuances:

The main shaft of the future design is equipped with a special flange, which is of the collar type, RU-32, which will then make it possible to easily screw on bridge type gearboxes.
Sprockets are taken from the UAZ and, together with a double-row chain, are installed on the future device and allow you to increase the distance from the gear axle to the ground. Timing sprockets allow you to increase the distance to the soil by 15 cm.
The housing type bearings are screwed to the main axle and their diameter is 30 mm.
The gearbox with gearbox can be constructed from the motor from the Karpaty motorcycle; it is necessary to provide a standard centrifugal clutch.
To install the cutters and then install the wheels, you need to use steel pipe.

You need to install a load in front of the frame that can hold the center of gravity.

A pipe with a diameter of 30 mm is welded as handles.

As soon as the chainsaw walk-behind tractor is ready, it can be tested on the site. To do this, fill up with fuel and try to complete the work. Modify your device if necessary.

The advantages of such a unit are:

the ability to use a variety of lubricants and combustible materials;
work in completely autonomous mode;
suitability for any type of work.

Let's look at how to make a walk-behind tractor from a chainsaw. The chainsaw works in all positions thanks to the fuel supply system; it is very powerful and unpretentious.

Choosing a chainsaw

If you want to make a homemade snowmobile, you need to start looking for a reliable and convenient chainsaw, which will serve as the basis for a future vehicle

At the selection stage, it is important to make sure that the parameters of the unit correspond to the required ones. First of all, power and efficiency are taken into account

Also, the chainsaw should not have a lot of weight.

To implement the idea of producing a homemade snowmobile, a Ural chainsaw is often used. It is characterized by increased reliability, low weight and good performance. In addition, the tool is environmentally friendly and is not afraid of working in difficult conditions.

Using such a chainsaw, you can make a high-quality unit that is capable of moving through any snow drifts.

As for the technical characteristics, they look like this:

Power - 3.68 kW.
Weight - 11.7 kg.
Dimensions - 46x88x46 cm.

The next popular model for the production of a homemade snowmobile is the Druzhba chainsaw. The unit has an affordable price and good technical characteristics. Based on it, you can create a good vehicle without unnecessary components and elements.

But the model has some disadvantages, including increased weight and low power (1 kW), as well as the lack of mounting points for fixing the safety casing. In some operating parameters, Druzhba is inferior to modern gasoline saws.

The Shtil chainsaw is also great for making homemade snowmobiles. Being an environmentally friendly model, it is completely harmless. At the same time, the device is characterized by low weight and almost silent operation when compared with domestically produced models. However, the cost of the powerful “Calm” can be prohibitively high.

Making a walk-behind tractor from a chainsaw with your own hands

According to the owners of land plots, who have already experienced all the features of handicraft motor vehicles from a gasoline saw, assembled with their own hands, “Druzhba” demonstrates excellent results after modernization. With the right choice of power plant for a homemade unit, it works no worse than its industrial prototypes.

The absolute advantages of this device are:

high power, reaching up to 4 horsepower in some samples;
lightness - a small mass will not make the unit heavier and will increase its mobility;
compact size - a small engine does not require reinforcement of the frame, which reduces the financial costs of its manufacture;
economical consumption of fuel and lubricants;
performance, which is determined by readiness for prolonged loads;
possibility of using all kinds of fuels and lubricants;
functioning in a completely autonomous mode;
applicability for various types of work.

The assembly procedure depends on the drawing used and may vary, but the main points of assembly include the following activities. The frame is assembled in accordance with the drawing.

The work process is organized as follows:

we take a metal pipe with a cross-section of at least 20 mm and bend it so that the overall appearance looks like 2 spars, the end of which is directed upward;
a motorcycle handlebar is welded in the rear area of the spar;
we strengthen the base with crossbars;
We electric weld the support platform for the battery to the rear bends of the side members.

Further work continues on the following points.

Now we mount a specialized flange, with the help of which the shaft will be fixed to the main structure of the unit from a gasoline saw.
We buy sprockets from a UAZ car at the used parts market. Through them, ground clearance (ground clearance) will be formed between the ground plane and the connecting wheel beam.
We take bearings with a 30 mm diameter. We fix them to the main bridge.
The gearbox, equipped with a gearbox, is assembled from a motorcycle engine.
The wheels and cutters of a handicraft cultivator are installed on a metal pipe of the required diameter.
Due to the fact that the walk-behind tractor has a low speed, a forced-type cooling system is required. The simplest solution is to install a fan. And so that the air flow is directed towards the cylinder, a protective coating is used. It could be an old motorcycle gas tank.

After completing the assembly work, be sure to test the equipment, doing this with extreme caution.

Do not forget to install the weighting material in the front part of the unit, firmly securing it to the body. This will enable homemade agricultural machinery to maintain its center of inertia. If the element is fixed unsteadily, the walk-behind tractor will shake during operation, which will lead to failure of the motor.

Homemade walk-behind tractor: choosing a power plant

The central question that everyone who decides to make such a homemade product will have to resolve will concern its motor part. It will depend on it whether the future walk-behind tractor will “pull” the loads placed on it or not.

In this case, there may be several options:

an old engine from a motorcycle, moped, scooter or even a car, which is not always on hand in good condition, and buying a new one can require a huge investment;
motor from professional trimmers;
motor component from high-performance chainsaws.

Each of them can become a good basis for a walk-behind tractor, but the most famous method is the one based on the use of a chainsaw.

The unconditional advantages of this method are:

high power, reaching up to 10 hp in some models;
lightness - low weight will not weigh down the walk-behind tractor and will add maneuverability to it;
compact dimensions - a small motor does not need a reinforced frame, which reduces material costs for its production;
economical consumption of fuels and lubricants;
endurance, which is determined by readiness for long hours of stress.

With the correct selection of the power plant for a homemade walk-behind tractor, it functions no worse than its factory counterparts.

Operating principle

A manual hiller works according to a seemingly primitive scheme. However, this has little effect on efficiency. One of the farmers presses on the traction handle located in front, and the other presses on the same handle at the back. As a result, the mechanism is set in motion, and the working disks are immersed in the ground. When moving, the soil layer is loosened, then, by installing or removing several special parts, they change the distance separating the disks.

Self-production of a hilling device is available to all farmers. All you need is basic mechanical knowledge and experience in day-to-day operation of agricultural machinery. Do-it-yourself equipment turns out to be much cheaper than factory-made analogues. There is no need to talk about satisfaction with one’s own skill.
