Options for homemade hand cultivators
This important function can also be performed with a shovel . But hard work doesn't pay off. Labor efficiency itself increases several times if you use mechanized soil tillage. Any owner of a small plot of land can make a manual plow with his own hands. Special tools may require a welding machine.
It should be noted that soil cultivation began a very long time ago . Several decades ago, at the peak of the garden and dacha lifestyle, such a tool was very popular. It was either bought from factories or made independently.
The most popular types of tools are:
- Flat cutter. This is a tool similar to an ordinary hoe. He is a mechanized version of it.
- Rotary, or star. This plow works on the principle of alternately cutting the soil with knife-shaped stars.
- Cultivator "hedgehogs". It works on the principle of a rotary plow, but the ground is loosened not by knives, but by steel rods that look like a porcupine.
- Tornado. This tool looks like an ordinary pitchfork, but its rods are twisted in a spiral. Additional mechanical devices cannot be installed; it is only a hand tool.
The scope of application of the devices is the widest. Cultivators can perform the following tasks:
- loosen the soil, thereby saturating it with oxygen;
- cut rows for sowing crops and sprinkle them;
- rid plants from the influence of weeds, etc.;
- used together with a walk-behind tractor;
- break up lumps of soil and level the ground.
How to create a hurricane
How to create a hurricane
Post by Ivan Bavin » 04 Jun 2010, 16:14
The topic is similar to “How to disperse the clouds”, but has a fundamentally different direction. I “invented” the method of creating a hurricane by accident. Those who are familiar with the “Small Heavenly Circle” and the “Greater Heavenly Circle” of qigong can easily try it. This is where it started for me. One day, returning home after work, I tried to spin the “great celestial circle” while walking. Then he turned it 90 degrees along the axis of the body. A breeze was blowing towards us. and, suddenly, the wind began to grow stronger and spin. Once I got the hang of it, I brought things to a hurricane several times. One day things got out of control. The hurricane did not want to die out, but then it stopped. We were on vacation in the south with our daughter. In the evening, when the sun was setting, a slight breeze blew. I decided to pull a joke on my daughter. He asked her to stand towards the wind and began to spin circles in front of her face. I asked my daughter how she felt. “Oh dad, I could barely stand on my feet. ". Morality. What is this game for? It will be easier to move further in understanding and applying energy phenomena.

A similar thing can be done at home. The wind can create a fan.
added after 2 hours 51 minutes:
For those who are unfamiliar with qigong, here is a description. You need to start standing, feet shoulder-width apart, facing the fan or an open window if a fresh breeze is blowing. In the future, this trick can be done on the go. You need to relax as deeply as possible. Maintain a state of relaxation continuously. Imagine a point or a small ball, we begin to rotate it around ourselves around the perimeter counterclockwise along the route: up the left arm, top of the head, down the right arm, right foot, left foot, up the left arm. Once you get the hang of it, 3-5 minutes is enough. The first time is longer. Depends on your skills and attention, first of all. Continue until a whirlwind appears in your face
Required materials and tools
In order to always be able to make some necessary products at the dacha, it is necessary to prepare the most popular materials in advance.
First you need to stock up on a lot of steel. It should be in every workshop. The number of different strips, profiles and pipes determines how many necessary tools you can make with your own hands.
Welding will be an indispensable tool in every household. With its help, you can quickly and reliably connect all the parts of various structures. Bolts and nuts are used as an alternative to welding, but the reliability will not be comparable.
Many people do not know where to start when assembling a hand cultivator with their own hands. Drawings are the first thing a novice owner should stock up on . You also need to have the following set of tools and materials:
- Profile made of steel, pipe or fittings. This material will vary depending on the model chosen.
- Wheel and fastening to it. As an alternative, you should take a bicycle frame.
- Handle. For this part, you can use both metal pipes and shovel handles.
- Welding. You can connect parts using welding, or you can use bolts, but it is advisable to have welding.
- Drill with a set of drills.
- Grinder with cutting wheel.
How to make a ripper with your own hands?
The device can be easily assembled independently from available materials. The advantage is that you don’t need to use fuel or electricity. All it takes is human hands. And even a person without much experience can handle the manufacturing. It will be enough to follow the recommendations.
To make such a unit, you must perform the following steps:
- Take a plastic pipe about 50 centimeters long.
- Make a blank from plastic. The size should not be slightly larger than the thickness of the handle-nozzle.
- The pipe is carefully cut lengthwise in order to turn it inside out. Then put it on the handle and secure it with tape or tape.
- If the handle was made correctly, the edges on both sides will be 25 centimeters long. Alternatively, attach small pieces of foam rubber/elastic to the edges to create additional comfort. So, your hands will not slip.
- The tip is made from reinforcement. It is he who will be assigned the main function. To do this, you just need to bend it with a hammer. The resulting bends should closely replicate those of the original.
These simple steps will keep the site in perfect condition.
Cultivator "Tornado"
Making such a cultivator is not difficult. Its base can be made of a metal pipe. It is necessary to weld steel rods to the end of the lower part of the pipe, thereby forming a square shape. After this, the rods are bent in a spiral direction, and the ends are sharpened.
As an alternative, you can use a bicycle handlebar as a lever, and instead of a metal handle, install a shovel shaft. This will significantly save your own effort during work.
Such a device is designed for digging out various roots at great depths, for preparing holes for planting trees, etc. It can be used as an electrophoresis for cultivating the soil with your own hands.
Stages of the existence of a tornado and tornado
The birth of a tornado
A tornado is born from clouds, which first take a funnel-shaped shape, then descend the funnel down to the ground. The funnel can have different shapes - there are options in the form of an hourglass, a column or pillar, or a whip. One or more funnels may appear at the same time. During hurricanes, dozens of tornadoes can appear, because at this time ideal conditions are created for them.
The first harbinger of an approaching celestial funnel is a sharp, sudden cooling of several degrees. Next you can see an approaching column, sucking in air and everything that comes along the way. Experts point out that much in the appearance of a funnel depends on its contents - color, shape and even sound largely depend on the materials collected by the funnel. And a wide variety of objects can fall into the funnel - after the end of the natural disaster, they return to the ground again. This can be extremely interesting precipitation, considering that a tornado is able to lift a car, or even a house.

How to make a flat cutter
Many people are looking for a cultivator for weeding. You can make such a weeding machine yourself. A profile pipe made of metal or steel is used as the basis for the frame. This base must be made of 2 parts. You need to weld at an angle of 30 degrees. A wheel fork made of a steel pipe or plate 3 millimeters thick is welded to the frame. The wheel itself can either be made independently or purchased. The steering wheel must be made of 2 steel pipes fixed to the frame.
The horizontal part of the frame is an adapter for the cutting attachment. Then you need to install a knife, which is made of steel tape 2-3 millimeters thick. Then the knives are sharpened. The sharpening angle can be changed or adjustable knives can be installed. If there is an old bicycle on the farm, then all the spare parts can be taken from it. Due to the large diameter of the bicycle wheel, the ride becomes very easy when working. The knife is made in the form of an inverted letter “P”, or T-shape. It should be noted that a T-shaped knife must be used very carefully between rows, as there is a possibility of spoiling the harvest.
A special subtype of the flat cutter is the design with forks. This device has several knives that are attached to a fork. It is made of steel rods, and they, in turn, are curved in a special way.
What are tornadoes and tornadoes?
The beginning of the formation of a tornado.
Tornadoes mainly occur in thunderclouds. They are atmospheric vortices that stretch from heaven to earth. Air masses are in constant motion, forming a funnel that sucks in any object in its path. The tornado is attracted to the surface by internal currents, while external currents rise upward. Thus, the air inside the tornado is highly discharged.
All objects falling inside a tornado can explode from the simultaneous effects of different pressures. Basically, such objects are considered closed buildings. A tornado spares no one.
Hand plow
Although such a device is called a plow, its intended purpose is contradicted. It does not have the classic properties of a plow. Even two people are not enough to work with such a tool. He is more of a classic cultivator. The device resembles a flat cutter, but an additional traction handle is installed.
Such a structure is handled by one person from the front, who acts as a traction force. And the second, the operator, controls the process of cultivating the land. It is impossible to use such a device without a co-pilot.
It is important to note that such a tool is not suitable for plowing soil for two reasons. The first is that a normal plow turns over layers of soil, but the device only loosens it. In addition, human power alone is not enough for normal plowing of the land.
What's inside a tornado?
Diagram of a tornado
Inside a tornado in the center is an area of calm with low atmospheric pressure. The air there is thin, making it very difficult to breathe. There are vertical air flows inside. A tornado can suck up even the most well-secured objects. This is due to the fact that the turbulence of the vortex is extremely high, and the speed is constantly changing along the entire trajectory of movement.
Interesting fact : few people were able to survive being caught in a tornado. They weren't even touched by the objects around them. People say that it is difficult to breathe inside a tornado due to the rarefied atmosphere, but in the center of the column there is a zone of relative peace.
Rotary or star
Making such a device is not a difficult task. To make the structure, you need 5-7 stars, which will serve as knives, strung onto the axle. These knives can be either straight or curved to the sides. After cultivating the soil with such a tool, it is recommended to walk between the rows and a flat cutter. A combination of two models is also possible, when the stars are first used in the design, and then a flat cutter is used for the final stage. This can significantly save the worker’s strength and energy. Since the stars perform the function of wheels in the design, an additional axle is not needed.
Working with such a tool is quite difficult, so only a physically trained person can handle it. In such a garden structure, you can install wheels of the same diameter instead of stars. In this case, you will get a good weeding hiller.
Classification of tornadoes and tornadoes according to the strength of the damage factors
Tornadoes are also classified according to the strength of the damage factors.
- Weak - they do not destroy very much, they develop a low speed - up to 30 m/s. Sometimes the roofs of buildings are damaged and small trees are broken.
- Moderate – up to 50 m/s. Destroys the roof of houses and can break cars.
- Causing significant damage – up to 70 m/s. They can overturn cars, break small houses, and tear trees out of the ground.
- Strong - develop speeds of up to 90 m/s. They destroy large buildings, lift cars, small trains, and ships into the air.
- The strongest ones develop speeds of up to 115 m/s. It can carry and destroy large structures, throw out cars, and destroy large objects.
- Super strong - develop speeds of up to 145 m/s. Destroys all objects and can transport large trains over significant distances.
- Destroying everything – moving at a speed of 145 m/s.
Cultivator "Hedgehogs"
For the base you need to prepare a powerful fork made of steel strip. In front of the tool there is a working axis with attachments. They need to be made from pieces of pipe onto which steel rods with pointed tips are welded. Actually, that's where the name comes from.
Loosening is carried out by lightly shaking the soil and piercing it, but the weeds remain in place, especially their roots. The main advantage of this subtype is the easy movement of the tool. Inter-row passage is carried out almost effortlessly.
Where and when does a tornado occur?
Map of the occurrence of tornadoes, tornadoes
Tornadoes constantly appear, over time they become more and more due to climate and weather changes. Now they are recorded not only in characteristic regions, but also in places where tornadoes were not previously noticed. Tornadoes mainly occur in the United States, with up to 800 tornadoes occurring there every year. Most houses have special underground shelters where residents go down during a disaster. Many weather services record tornadoes daily. In 1965 alone, 37 tornadoes occurred simultaneously.
Interesting fact : the wind currents are so powerful that even light and small objects in the whirlwind can damage trees and buildings encountered in the path of the disaster.
Average distribution of tornadoes in the US per year
In spring and summer, the air temperature around is stable and is maintained at fairly high levels for several weeks. It is in such places that tornadoes occur much more often. In winter and autumn they are seen less often. The most active months are May and June. Then a tornado occurs during the day and evening during severe thunderstorms and heavy rains. At night, tornadoes practically do not occur.
