Making a harrow for a power tiller with your own hands

Rules of harrowing with a power harrow

Each case of application of such a versatile farming technique is quite individual, but there are a number of general recommendations, which should be adhered to to improve the quality of the result and facilitate the process:

  • Before starting work, it is advisable to make a test run, checking whether there is enough force to work effectively (if necessary, increase the pressure in the system or change the gear), whether the depth of entry is satisfactory, the degree of shredding at the outlet, whether the angle of attack is sufficient.
  • While working with a harrow, especially if it is a self-made one, it is important to monitor the angle of the tool to the frame and to the cultivated surface. If it is strictly vertical, and there is not enough effort for the system to fully dig out the roots, it will simply start to drag the soil in front of it, clogging itself with lumps and plant debris.
  • Very convenient to meet the varied situation of plots, even in the same field to place the working tools in different rows of the product at different angles. Then, to get a better result, you can simply swap rows during work or, if such a possibility is not provided, to loosen or tighten the fasteners where it is necessary.
  • If it has been noticed that the tines, disc notches or rotor blades are clogged. the working tool is removed to the surface and thoroughly cleaned.
  • it is important to see to it that each working tool “leads” its own furrow to increase working efficiency and to avoid necessity of repeated passes over areas that do not give in, and that their complex is evenly distributed on the frame and has the same depth in comparison with their neighbors.
  • The depth of the passage can be adjusted by increasing the weight of the weighting elements of the power tiller body.

The other nuances, as a rule, are learned only by practice, when each operator selects the form of work convenient to himself.

What functions does the tool perform?

The tasks of the harrow are quite extensive. Its design becomes more and more perfect every year, which allows to use it for different purposes. These days, the product is designed for such tasks:

  • Keeping the soil from drying out;
  • Leveling the surface of the plot;
  • Effective removal of weeds;
  • Breaking up the top layer of soil.

Equipment of this type has found its use before sowing, when it is necessary to break up frozen pieces of soil and level the ground. Also, the harrow for the power tiller is used immediately after the harvest to prepare the site for winter.

Disc harrow for power tiller

The disc harrow is used for loosening the soil up to 10 cm deep with a hard dried crust in order to soften it, for incorporation of green manure, shallow early plowing before the weeds sprouting for sowing cereals.

Disc harrow has a more complex design, compared to the device of a tooth harrow, as it has rotating elements, on the work of which the overall result depends. The angle of the harrow discs on the soil surface also affects the result. The overall design of the harrow can be supplemented with a shock-absorbing suspension and traction, which regulates the angle of the discs.

Making a disc harrow for a power harrow: what is needed

To make a disc harrow for a power harrow, we need:

  • 8 spherical/bowl-shaped/star-shaped discs with a diameter of 445 mm and a metal thickness of 4-5 mm; to reduce soil resistance, you can make cuts around the disc with an angle grinder of your choice;
  • 1400×650 mm frame made of 45×45 mm section pipe with 4-5 mm wall thickness
  • a rod with a length of 1500 mm and a thickness of 50 mm, on which the discs will be placed;
  • two bearings with 50 mm diameter boom mountings.

Assembling the disc harrow for power tillers

The bar is threaded through the central holes of the discs and holes in the frame so as to be in its center and parallel to the sides of the frame. The discs and the boom must be fastened together with a welding machine. The ends of the boom are fixed in bearings, which in turn are mounted on the outside of the harrow frame so that the entire boom, together with the discs, will rotate as it moves. the harrow discs must be in contact with the surface and the sharper the angle of attack on the surface, the more effective the harrowing will be. The whole harrow construction is attached to the frame of the power tiller both with a rigid hitch and with a hanging system. If you make this device in smaller proportions, you can make 2 disc harrows, which will work the ground simultaneously at different angles.

Tool types

The harrow is an agricultural tool used in tillage. Harrowing prevents soil from drying out, levels or breaks up the soil and kills the weeds. Such a construction for planting potatoes, with their own hands made according to the drawings, allowed to crush large lumps of soil formed after plowing.

It is known that such implements appeared at the very time when people began to cultivate the soil with an ordinary harrow. Back then, such plowing tools were very large, lacked maneuverability, and weighed a lot.

In ancient times horses were used for harrowing. Nowadays, when tractors appeared, metal harrows for a single-axle tractor began to be used, which can be bought or made by yourself. They are able to break through clods, cover the soil to keep moisture longer, and even collect the remains of dry grass. The tool is able to remove weed roots with ease, and the harrow hitch helps speed up this process by half.

It is accepted to distinguish 3 kinds of harrows:

Looking at such different and useful items of labor, you can note their marked difference in weight. All industrial models are hooked on agricultural machinery. The traditional bow is used in particular for loose ground. Such a hinged design helps to retain moisture and thus prevent the soil from drying out.

Homemade tool is installed manually. It performs the crushing of large clods, removes weeds and residual vegetation. The self-made harrow for a power tiller weighs very little, and is most often used for crushing lumps of earth and shallow loosening.

  • The disc harrow is usually used on parched soils and practically does not differ in functionality from the rotary (active) harrow. The only difference is that here the working body is made of discs installed on independent axles, and the attachment to the power harrow is made by coupling.
  • Tooth type. This type of equipment is considered the most common in agriculture. This self-made harrow for the tiller is suitable for crushing and loosening the soil after the plow work. Farmers use this machine when removing soil crust after rain, spreading fertilizer, seeding and even removing weeds.

There are 3 types of tooth harrows:

Massive tines are the main organs of this device on the minitractor. There are 2 types of harrows by structure: square, reticulated. The first belongs to the category of medium or heavy harrows. For easier work, including small plots, the harrow is more often used.

Tooth harrow for power tiller

Tooth harrow has an uncomplicated design, but it is necessary to carry out harrowing of the milled and leveled soil surface just before the planting of crops. The phrase “all that is simply brilliant” perfectly describes the working principle of a toothed harrow. A toothed harrow is essentially a large rake with several rows and many tines that crushes and levels the ground on its path with a power harrow. But the primitiveness of tillage with this device does not affect the effectiveness of the harrow.

Preparation and materials for the toothed harrow of the power harrow

The easiest thing would be, of course, to adapt a manual tooth harrow for the tiller, which is powered by human or horse traction, but if you do not have one, then let’s start from the beginning. And in the beginning you will need to acquire the tools that you will need to make a tooth harrow for a tiller for a tiller by yourself, and these are:

  • welding machine;
  • angle grinder with metal disks;
  • Chains to attach to the power tiller;
  • strips, pipes, channels, beams;
  • Angles with a metal thickness of 3-4 mm;
  • pieces of rebar or bolts, 15-20 cm long and 1-2 cm thick, with one pointed end as a harrow tine.

Assembling the design of a tooth harrow for a power harrow

First we need to determine the scheme of assembly of our harrow. A square harrow is a square frame with strips of metal welded on it at an angle of 90 degrees. Mesh harrow is a frame and metal strips fixed to each other at an angle of 45 degrees with a diamond pattern. You may also make a wave, herringbone, and chevron pattern by welding slats at the same 45 degree angle on several parallel beams. This harrow will be subject to fewer bending stresses.

Remember that the dimensions of the harrow frame should not exceed one meter in width, because it will be too large a load on a single-axle tractor, and in length it should not exceed the length of the handles of the power tiller, because this will interfere with your work with the power tiller. The optimum dimensions for a square harrow are 720 mm wide and 480 mm long. The bars should be welded 80-100 mm apart for maximum effectiveness. In a wave harrow the bars are 162 mm apart and the beams 181 mm apart, as shown in the diagram below.

The harrow tines are welded at right angles to the intersection points of the bars. Often the rows in the harrow are fixed with an offset, so that each tooth leaves a trace that will not repeat the trace of the predecessor, or they are welded in staggered order. Also it is necessary to weld all the teeth of the harrow so that they are on the same level and none of them digs into the ground more than the others.

The harrow can also be made up of several sections connected to the frame/beam and to each other by chains.

Hitching the harrow to the power harrow

The outermost chain links are welded to the approximate center of application of the ready harrow’s force. The other end of the chain is attached to the coupling by bolts or by welding. It is important that the resistance of the harrow tines should be symmetrical to the axis of the pull, otherwise the harrow will be pulled to the side and won’t dig into the ground and perform its function. Check that the harrow is not leaning to the side. If necessary change the coupling point on the harrow.

Thanks to the simple and robust design you can attach weights of different sizes and shapes to the tooth harrow if necessary.

For the Neva power harrow

The Neva motor blocks are considered to be the market leaders in agricultural machinery for small arable farming. The diameter of the shaft of the Neva motoblock is 30 millimeters.

This power tiller model is notable for its high output and resistance to soil composition. Ideal for small farms because of its mobility and maneuverability.

Just a few hours of power tillage quality harrow your land.

Till the ground so that it is evenly enriched with useful elements. Usually harrows in early spring after the snow melts and in autumn when the harvest is completed.

Neva power tillers are equipped with gasoline engines. The tiller has various applications.

Due to resistance to temperature fluctuations the machine can work up to 4 hours without interruption, even in hot weather.

If we talk about the amount of cultivated land, the tested volume reaches 6000 m2 without stopping. The single-axle tractor can be used not only with a trailed harrow, but also as a snowplow. This is, by the way, if you need to plow arable land, and in some places there is still snow. Here you can use the Patriot and Proab power tillers.

Simply swap out the trailed implement by detaching the harrow and fit a snowplow bucket.

The advantages of a disc harrow

The disc harrow is an excellent implement that can be used successfully instead of a plough, cultivator, or husk. It is well suited even for soils with very little moisture.

Harrowing is carried out in the following cases:

making, harrow, power, tiller
  • When you need to break up the top crusty layer of soil that has been formed by moisture, sun and wind over a long period of time.
  • To mix and incorporate fertiliser in the soil.
  • If you want to level the ground.
  • When dense, growing crops need to be thinned.
  • To kill existing weeds in the vegetable garden or field, as well as to shred dead wood. Any disc harrow shreds sunflowers and corn.

Only a disc harrow of good quality can cope with such tasks, made with taking into account all technical nuances. With our free 3D models you can make your own disc harrows for sale. If you follow all the details of the samples, your harrows will be just as good as their factory-made counterparts!

Important! Only use the harrow at a speed above 7 km/h. That way the harrowing process will be as efficient as possible.
