How to make a rotary harrow for a walk-behind tractor ... that's why making it able to work, and with your own hands, is as easy as shelling pears. ... The disc harrow is used where there is little soil moisture, where it often dries out.
Both industrial large-scale and private, and even amateur farming cannot do without loosening the soil. On a flower bed with tulips or a garden bed with dill with an area of a couple of square meters, a hand hoe will successfully perform this operation. A plot of ten acres (one hundredth is a plot of land of one hundredth of a hectare with an area of 10 x 10 = 100 m 2), sown, for example, with potatoes, will most likely require more powerful agricultural machines. And for loosening the soil, you need a harrow. Tooth or disc, home-made or factory-made, aggregated by a walk-behind tractor, horse-drawn or even human. The most common and simplest type of harrow is tooth harrow.
It is not difficult to make such an agricultural tool with your own hands. It is important not to be mistaken with the size and weight, so that the harrow, instead of promoting the harvest, does not “bury” it. So, more about everything.
Types of surface tillage. Processing without seam turnover
There are few ways (types) of mechanical soil cultivation. In different sources, they can be classified in different ways and differ in names. So, processing implies, in addition to compaction (rolling, slapping, pressing), three types of loosening:
Loosening of the soil with a seam turnover;
Loosening without seam turnover;
Loosening with leveling.
If we are talking about preparing the soil for the winter in central Russia, then this is most often loosening with a seam turnover, or plowing. Different types of plow shares provide different results. So, a plow with a cylindrical surface of the share wraps the layer partially, but breaks it along the entire length, providing along the way a good loosening. But the screw ploughshare turns the layer exactly 180 °, keeping it practically unchanged and well seeding weed seeds to a depth (where a significant part of them die due to removal from light and heat).
Some types of harrows also partially wrap the seam, for example, the Tooth harrow, its “relative”, refers to agricultural implements that loosens with leveling.
Harrowing targets
What is harrowing generally used for? After all, there is plowing, cultivation. These agrotechnical methods loosen the subsoil layer, promote air nutrition of the root systems of crops. And what, in comparison with a plow or a chisel, a tooth harrow? Easy processing of the surface itself, no more. But this kind of impact on the field is sometimes in demand.
A simple example. The field is plowed on loams, there is no rain for a week, but on the contrary - the sun heats up the giant lumps of earth formed during the plowing process, and a warm breeze drives out the remnants of moisture from them. What happens if grain drills are simply put into such areas? Anything but sowing grain. You should not wait for a harvest with such farming.
If the land is located on difficult heavy soils, a tooth harrow will work successfully after plowing. The heavy construction, bristling with metal teeth, will break heavy clods.
And already a flat surface, now consisting of lumps no more than a few centimeters in size, will not dry out ahead of time and will be ready to give life to a new crop.
Tooth harrow classification
Conventionally, the tooth harrow can be divided into three classes:
Heavy (one tooth of such an agricultural tool presses on the ground with a force of about 2-3 kg);
Medium (tooth pressure from 1 to 2 kg);
Light (no more than one kilogram - the pressure of the tooth of this harrow).
Recently, the classification is rapidly changing due to the increasing use of aggregates for integrated soil cultivation. Such a machine in one pass wraps the layer, destroys it to lumps of a given size, levels the surface, and, if necessary, compacts it and even applies mineral fertilizers.
Application of different types of harrows
The most difficult soils from the point of view of agricultural technology are clays and loams. A heavy tine harrow is used to break up clods after raising the plow (reverse plowing) or chiseling. The hitching of such implements is aggregated, as a rule, with tractors of the 2nd class and above.
Previously, the use of such couplings was a whole event. The hitch itself and the harrows included in it were delivered to the work site in a trailer. It took several people in order to collect all the links of agricultural implements together. Modern hydraulic tooth harrows are easily serviced by one operator. Directly on the field, the harrow is moved from the transport position to the working position thanks to the presence of hydraulic drives at the touch of a button.
Medium harrows work on light soils - sandstone and sandy loam. But the use of light harrows is not associated with the type of soil, but with technology. With their help, "moisture closure" is most often performed - breaking the crust formed after precipitation. This is done in order to destroy the tubules through which moisture was absorbed into the ground - to preserve water for plants.
Weed control is also carried out with the help of light harrows. Weeds that have just sprouted from the seed are pulled out to the surface along with the roots and die from dehydration.
DIY harrow
The design of the tooth harrow is simple. The simplest agricultural tool for loosening and leveling the soil layer is made like a regular wooden trellis. The distance between adjacent teeth, if we talk about small household plots, can be planned in the range from 100 to 200 mm.
The teeth can be inserted into the grid nodes in different ways:
The easiest way is to hammer in nails of sufficient thickness with subsequent biting off of the caps. Not the best solution from the point of view of reliability, suitable for a light harrow (weed control, until the cultivated crop has emerged, moisture cover).
Instead of nails, you can use thick self-tapping screws, and the non-threaded part remains outside, as a working area.
Pieces of reinforcement 8-12 mm, driven with guaranteed interference into pre-prepared holes.
A harrow made of metal will be better and more reliable. As strips, you can use any available rolled metal: corner, channel, pipes, etc. Just do not weld the teeth (they are most often used as pieces of steel reinforcement) directly to the surface of the harrow. Such a tooth is likely to break off quickly. Holes are drilled in the rails in advance, the prepared rods are inserted and their exit points are scalded on both sides.
For areas with difficult terrain
You can make a do-it-yourself tooth harrow with a slightly more complex design. It will work great as a lightweight harrow for breaking up capillary crust as well as for killing weeds. A feature of its design is the articulated articulation of the elements.
Such a tool will perfectly cope with weeding due to its segmented structure - not a single depression or bulge of the sown area will be left without the "attention" of its teeth.
Rotary tine harrow
Appeared in domestic plant growing relatively recently. It is most often used in the cultivation of potatoes. After passing such a harrow, the farmer receives the correct trapezoidal bed. The harrow perfectly pulls out weeds and loosens the soil remarkably. Importantly, it can be used until the very bloom of the potato - the teeth of the rotors practically do not damage the stems of the plants.
Another plus. After passing the rotor, the potatoes end up in the beds at an elevation relative to the general field level. Due to this, since the ridges are warmed up better, earlier and more friendly crop shoots are provided.
A harrow for a walk-behind tractor is an agricultural tool attached to this unit or mini-tractor.
The mechanism is designed for the following purposes:
- loosening, mixing and leveling the soil without turning it;
- weed removal;
- thinning of thickened crops;
- destruction of dry crust on the ground;
- embedding of seeds and fertilizers into the ground;
- increased aeration of the earth.
The impact on the soil occurs with tools fixed on a common frame, such as:
- teeth;
- hoe;
- disks.
Harrowing with a walk-behind tractor is an important agrotechnical process of processing land plots to increase yields, quality of grain and technical products.
Harrow varieties
Harrows for agricultural work are divided into types:
- dental;
- disk;
- rotary.
A tine harrow is a simple mechanism, which is a metal frame with teeth of the required length attached to it. The power of the walk-behind tractor affects their number and frame size. The teeth are placed in the form of a zigzag or rectangle and are attached to the frame rigidly, pivotally or on a spring stand.
The harrowing depth depends on the setting of the tines. When they are installed with a sharp edge forward in the direction of travel, the depth of loosening increases, when installed backwards, it decreases.
A disc harrow differs from a tooth harrow with a processing tool. Instead of teeth, spherical discs with a smooth or cut-out cutting edge are attached to the frame and placed at an angle called the angle of attack. It changes and is 10-25 °. In the process of cultivation, each disc cuts off the surface layer of the earth, intensively breaks the roots of weeds, mixes them with the ground and compacts the soil. When harrowing, agronomists recommend using a needle harrow. The needles pierce the soil and loosen it.
Disc mechanisms are aggregated with a walk-behind tractor using a front or rear suspension.
The rotary harrow is better than other mechanisms for initial soil cultivation. The depth of penetration into the ground is 7 cm, but this factor does not prevent it from being used for loosening virgin lands. It resembles in appearance a cultivator and a disc device.

The rotary tool for the walk-behind tractor consists of 6 edges, a disc and a sleeve. Its working elements are pointed plates, which are located at different angles.
The power harrow is mounted on shafts instead of wheels or a tiller, which greatly increases its productivity, especially on virgin and heavy soils. For high-quality work, it is better to aggregate to high-power walk-behind tractors with gearboxes.
DIY tooth harrow
A homemade tooth harrow for a walk-behind tractor differs from the factory quality of the material from which it is made. The factory model is made of structural steel that can withstand heavy and intense loads. Let's take a look at how to make your own harrow with the same properties.
A do-it-yourself tooth harrow for a walk-behind tractor can be made by any craftsman. This process is not difficult. The design is simple and does not have complex connections.
First, you need to design a harrow for a walk-behind tractor with your own hands with drawings that give an idea of \ u200b \ u200bthe dimensions, connection nodes and the general scheme.
The tool is made of steel strip, square tube or angle.
The algorithm for making a dental device is as follows:
- Metal strips at an angle of 30 ° to each other are welded to the pipe from the bottom. The edges should protrude evenly on both sides.
- In the middle, a sleeve is installed by welding. With the help of a finger, the harrow is connected to the walk-behind tractor through the bushing. Lift height should be adjusted with a tine for the depth of loosening.
- At each edge of the steel strip, teeth are bolted or welded.
- The drawbar is mounted on the sleeve.
- A screw is attached to the drawbar to adjust the position of the teeth. The front and rear tines must run equally into the soil.
Experts recommend manufacturing harrow working elements from hardened steel. The teeth are best made of corrugated reinforcing steel with a diameter of 10-14 mm and a length of 10-20 cm. The longer the teeth, the thicker they should be. Before attaching to the frame, they must be sharpened and hardened, otherwise they will bend.

A do-it-yourself tooth harrow for a walk-behind tractor is an excellent assistant for small farmers and summer residents who process their plots.
DIY disc harrow
The disc implement is a more advanced model that performs more functions for tillage. The design is more complicated, so it is better to buy a ready-made device on the industrial market. But for those who are not afraid of work, you can make a disc harrow yourself.
Today, quite a lot of people living in rural areas own a certain land plot. In order to have a decent harvest from it, it is necessary to properly care for the soil. For these purposes, a person needs a special technique. For example, for processing the soil before planting, a device such as a disc harrow is very actively used. Let us dwell in more detail on its design and application for MTZ.
Description of the mounted disc harrow for MTZ 82 for tillage
A disc harrow is an agricultural unit that can become a worthy replacement for a cultivator, plow, or stubble cultivator. Thanks to this attachment, it becomes possible to cultivate land with a moisture level of no more than 25%. What it looks like and how to choose the right one is indicated in this article.
This type of hinged structure consists of a specific number of discs. Relative to the vertical main axis of the structure, they are concentrated obliquely. This is what allows you to adjust the depth in the ground and determine the angle of treatment.
The video shows a disc harrow for MTZ 82:
According to the design of the working part, this device can be made into two types: hinged and mesh. You can learn how the Polesie combine harvester is used from.
When the land is being cultivated, where there are many roots from previous plants, it is extremely profitable to buy a disc harrow designed for stony soil.
The mesh design is of the old model, but it has already been tested by time. The base of the product is made of a metal mesh, on which the teeth are attached in various ways. The installation of the teeth can be different, taking into account the set purpose. The teeth can be presented in a curved form, straight and as a spring element.
For a more correct distribution of fertilizer, loosening the land with residues of vegetation, it is necessary to use a harrow with discs that can increase the stability of the soil surface to various kinds of erosion processes. It is also imperative to increase its absorption capacity.
Also, the presented devices, working in tandem with the MTZ 82 tractor, can be divided according to their intended use. and other data are indicated in the article.
Field
They are used to cultivate the land after cultivation activities. Certain models can be equipped with boxes that serve for ballast weight. Thanks to such measures, it is possible to process the soil to a sufficiently large depth.
Trailed garden for tractors
This type of construction is characterized by its light weight. Serve for soil treatment between rows in the garden and in the vineyard. When using such a harrow, it is possible to loosen the ground to a depth of 10 cm. Other features of the unit are indicated in the article.
Swamp
Processing can be carried out to a depth of 20 cm.
This type of device is actively used for disking on swampy soil and for cultivating virgin lands.
A disc harrow for installation on an MTZ 82 tractor is a device to which the battery with working parts is fastened. Cultivation of the soil is carried out using steel discs with dimensions of 450-510 mm. It is the steel discs that belong to the main working bodies of the harrow. and other technical data can be emphasized for yourself from the article.
If several such elements are placed on one axis, then it will be possible to get a battery. Its fastening is carried out using bushings. Due to this, the battery will rotate while the tractor is moving.
On the video - trailed disc harrows for MTZ 82:
In most cases, the installation of a battery with discs is carried out in several rows. The plane of penetration of the device into the ground is called the angle of attack. Its value can be 1-20 degrees. It is necessary in order to determine the hardness of cultivated land. The harder it is, the larger the given angle should be. You can find out how to make a manual potato hiller with your own hands.
The disc harrow works according to the following principle. The battery, which is mounted closer to the tractor, disintegrates the soil. But the second battery closes it. To perform cultivation with maximum efficiency, it is necessary to achieve displacement of the disks of the front and rear batteries relative to the axis of each other. The tractor begins to move around the area at a speed of 15 km / h. The discs, focused on the first battery, begin to break through the layer of the earth to a certain depth. The soil rises, since the disc has a spherical structure, moves to the side and is laid from a low height. and the technical parameters of the equipment can be seen in the article.
The second, in a similar way, returns the land to its place. The result of such processing is the turning and crushing of the soil. With an increase in the angle of attack, the discs will go deeper into the ground.
Scope of application
Disc harrows are an irreplaceable thing in the life of many farmers. The main advantage of such products is their versatility and high performance. It is possible to carry out processing to a depth of 3-5 or 18-25 cm. Based on this, it can be concluded that the presented devices are advisable to be used with a wide variety of tillage technologies.
In most cases, such mechanisms are used for loosening the soil, harvesting, removing stubble, crushing the soil cocks.
There is also an auxiliary technique, thanks to which it is possible to carry out the sowing of the crop. Thanks to this, the harrow becomes a modern seeder, which also combines a device for soil cultivation. You can find out how to use a hand cultivator for a summer residence.
Today, most farmers confuse universal disc implements with classic ones. The second option is characterized by the presence of a rigid suspension system of the working element. Universal means for soil cultivation in their design have a two-row parallel concentration of working elements, and all pairs are connected by a disk independently. This ensures that crop residues are maximized through the space between the discs. As a result, the degree of clogging is reduced, which makes the working element less vulnerable. Learn how to use the Mantis cultivator by.
The presented type of machine can also be equipped with a roller, so that it can be used for further leveling the treated soil, closing moisture in it. Then the growth of sown crops will be much better.
Price
It should be noted right away that the cost of the presented devices is not so high. Therefore, every farmer can afford it. It will be possible to buy disc harrows for 44,000-98,000 rubles.
How to make a homemade one with your own hands
If you do not have extra money to purchase a disc harrow, then you can do it yourself at home. You can use as the main material:
- two-inch pipe,
- U100 channel welded into a square frame,
- wheels from an old Zaporozhets,
- two wheels from a trailed KPS,
- medium-sized harrows 5 pieces,
- rubberized belt.
On the video - do-it-yourself disk harrows (homemade):
Disc harrows are a unique design, thanks to which it is possible to cultivate the soil necessary for sowing crops, harvesting. In agriculture, it is very difficult without such a device. In addition, poor-quality soil cultivation will negatively affect productivity. In our other articles, you can read.
To expand the functionality of walk-behind tractors, their owners equip their equipment with attachments.
Some owners prefer to buy inventory in stores. Others make devices with their own hands. Below we will consider the types, functions and manufacture of a harrow for a walk-behind tractor.
What are the functions of the inventory?
The tasks of the harrow are quite extensive. Moreover, every year its design becomes more and more perfect, which allows it to be used for various purposes. Nowadays, the product is designed to solve the following tasks:
- Saving the soil from drying out;
- Leveling the surface of the site;
- Effective weed removal;
- Destruction of the top layer of the earth.
Tools of this type have found their application before sowing, when it is required to break up frozen pieces of soil and level the ground. Also, the harrow for the walk-behind tractor is used immediately after harvesting to prepare the site for wintering.
Types of equipment and their description
There are several types of inventory. The most common designs include:
- Tooth harrow;
- Rotary harrow;
- Disc harrow.
Each of these types has found its application in different situations. Below we will consider the features of each type of harrow for a walk-behind tractor.
Applications for tine harrows
The first type of product is used when the farmer seeks to obtain loose, even soil. The teeth are evenly spaced throughout the structure, and can be of different shapes and sizes. Most equipment owners perform harrowing with a walk-behind tractor with equipment equipped with square teeth, although sometimes equipment with round or knife teeth is also used.
You can fix such a harrow to the walk-behind tractor by connecting it to the frame. For this, hinges or a spring strut are used. Often, farmers use a walk-behind harrow, which is attached by means of oscillating or rotating frames. Rotary harrows are used quite actively on the farm. They are quite reliable and perform a wide range of functions.
Rotary harrow - functions and design
A rotary harrow for a walk-behind tractor, or, as it is also called, a rotary design, is in demand due to its ability to quickly and efficiently remove the topsoil. Depending on the goal, the equipment can be buried into the ground by 5–8 cm. When choosing such a product, one should start from the size of the site. In most cases, farmers buy a structure that is 140 cm wide.
When buying such equipment, you should pay attention to the position of the teeth. They must be welded at an angle and have oblique blades. Such a device will work effectively for many years.
The essence and purpose of the disc harrow
The use of such equipment is very similar to processing with structures of the previous type. The main difference lies in the design, which uses discs mounted on separate axles.
The disc-type power harrow is often used on dry soil. As practice shows, with frequent operation on wet ground, the device breaks down very quickly.
Features of making a structure with your own hands
Before making a harrow, you need to prepare materials and equipment. You will also need to make rough drawings. They indicate the dimensions of the structure, based on the parameters of the walk-behind tractor.
If the technique is not very powerful, then you should not make too large a device.
The algorithm for making a homemade structure is as follows:
- First you need to make a frame - for this, weld metal corners together;
- After that, the hitch is made. To do this, you can take used hinges from an old car and connect them to the frame;
- Further along the perimeter and in the middle of the frame, metal teeth are welded.
At the end, the product can be painted so that it does not corrode. It will be especially necessary to paint the teeth, since they are in contact with the moist soil.
