Do-it-yourself disc harrow for a tiller

Types of harrows for tillers and tractors

First, consider a rotary harrow for a tiller, it removes the top layer of soil very well. Using a rotary harrow, after harvesting grain crops, they cultivate the land. It is also a good option for leveling the soil. Thanks to it, there is no need to mow the grass. The working depth is set based on what tasks are set. It usually fluctuates from 5 to 7 centimeters.

For a tractor, it does not matter at all what the harrow will be, here it is more important and valuable to take into account the dimensions required for tillage. If the field is several hundred hectares, the wider the harrow, the better.

A large harrow is made specifically for tillers, so making it yourself is not difficult. It is attached to the tiller on the hitch.

The farmers concluded: for good efficient work in the field, the harrow, or rather its blades, must have an oblique shape. The teeth should be located at an angle to the plane of the ground, this allows you to cut easily, and thereby leveling the soil.

DIY tiller harrow and proper tiller harrowing

In order to increase the yield in the field, they always plowed and harrowed the soil. Our ancestors did this, and modern agrarians do the same. But in order to do this work, horses were harnessed in the old days, and today the harrow is attached to tillers (for small farm plots, private summer cottages) or to a tractor (this is for large farms in large areas). Based on the foregoing, a do-it-yourself harrow for a tiller is an important tool for any summer resident, below we will take a closer look at the manufacturing process and how to do the correct harrowing with a tiller.

Disc harrow

The second type of disc harrow, application to dry soil. A disc harrow performs all the same functions as a rotary harrow, only it differs in design: it uses discs, each of them stands on a separate axis. But, unfortunately, this type of harrow breaks more often.

The classic tine harrow is used in places where an even and loose soil layer is required. The teeth are evenly spaced in the frame, their length ranges from 25 mm to 45 mm. The size of the teeth depends on the weight of the harrow, the more the weight, the larger the teeth. The disadvantages include the speed of the tiller’s efficiency, the power should be significantly high, and be at least 12-14 km / h.
If you are faced with a choice, then for work in small areas, a rotary harrow for a tiller is perfect.

Robot principle and tiller harrow design

The first harrow, which a man made with his own hands, looked like spruce logs tied together. They were made not very long so that there was an opportunity to maneuver in the fields, but the mass of the harrow was too great, which made it possible to break blocks of earth after plowing and retain natural moisture in the ground.

Today this unit is used both independently and with other types of devices such as seeders and cultivators. The harrow copes not only with earth boulders, but also covers the soil leaving moisture inside it. The technical characteristics of the harrow also allow it to collect dry plant residues and pull out weed roots.

This is a device that has passed centuries and has been modernized so much that when using it, a minimum of human effort is required. Harrows are of several types:

  • disk
  • rotary
  • dental
do-it-yourself, disc, harrow, tiller

The technical characteristics of the harrow correspond to generally accepted standards and are calculated based on the mass per disc or tooth. Accordingly, based on this classification, there are heavy, medium and light harrows. And their use can be special or general.

What the harrow consists of?

Metal strips are welded to the bottom of the square pipe, at the ends of which teeth are bolted in two rows. These strips are placed at an angle of 30⁰ to each other, the stakes of the earth, which slip between the teeth of the first row (front), break against the teeth of the second row.

The drawbar ends in a welded sleeve, through which the harrow is fixed with a “finger” to the tiller. Lift height adjustable with a tine for the harrowing depth.

An adjusting screw for the angle of attack is welded to the drawbar next to it. it is he who allows you to adjust the structure so that the rear and front teeth fall into the same depth.

Features of using the harrow on the tiller

Sometimes the harrow becomes clogged during operation. It is very easy to clean it without even bending over. When lifting the tiller handle, we tear off the harrow from the soil surface, set it aside and discard all the debris that has accumulated on the teeth with our feet. Then we return the tool to its original place, lower it and continue moving.

Correct tiller harrowing

A good quality rotary tiller harrow can be used as a cultivator. Everything that is done manually in the absence of equipment will be done quickly and efficiently, when you have a tiller and a harrow for it in your arsenal, then by carrying out the correct harrowing with a tiller you will increase the yield of the planted crop, and significantly reduce the level of seed loss and ensure the delivery of fertilizers to the desired depth.

The harrow for the tiller helps to level the top layer of the soil, when fertilizers are poured onto the ground, its work ensures that they fall under the top layer of the earth by 5-7 cm in depth.

Advice: when working with the harrow using a tiller, do not exceed the speed of the mechanism more than 4 km / h.

Harrow for a tiller: do it yourself, drawings, disk, rotary, how to make

Rotary harrow. function and design

The rotary harrow for the tiller, or, as it is also called, the 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 in the ground by 5–8 cm. When choosing such a product, you should start from the size of the site.

In most cases, farmers buy a structure 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.

Tiller harrow

At the stage of preparation for the sowing campaign, various works are carried out: plowing, loosening, leveling, and weed control. For this, a harrow is needed that performs several different functions at once.

Tiller harrowing is performed using different harrows (disc, tooth, rotary type), each with its own distinctive properties.

Rotary harrow

The rotary harrow attached to the tiller is a mixture of a cultivator and a disc-type harrow. The main advantage of such a device is that it perfectly removes and levels the topsoil, and the processing depth is adjustable. It is necessary to correctly determine the ratio of the width of the structure to the power of the tiller for the most efficient performance of work.

The bending of the teeth of such a device directly depends on the radius of the disc and the amount of sliding of the wheels of the traction unit. The more adhesion to the soil, the more the tooth bends. It enters at a 90 degree angle and improves soil oxygenation.

When using the rotary harrow, large plants are practically not damaged, while weeds that have opened the root system shallowly are pulled out. The resulting aeration promotes the flow of minerals and organic fertilizers from the air.

Rotary harrows are active and passive. The active type is more often used, where the structure is installed instead of the front wheels of the tiller. But at the same time, the traction unit must have greater power and the ability to carry out different speeds. When used with other equipment, you can not only loosen the soil, but also level the soil.

Among the advantages should be highlighted the ease of use of the structure, long service life and efficiency of work. The only drawback is the high purchase price and the significant size of the device.

Disc harrow

This is a more advanced device, in terms of the number of functions, providing effective soil cultivation. The disc harrow has many complex design features, so it is recommended to purchase a finished product, and not try to do it yourself.

The unit can be either lightweight, attached to a small tiller up to 100 kilograms of weight, or heavy, the maximum weight of the traction device is up to 200 kilograms.

The disc harrow got its name from the working element, which is round discs with a diameter of about half a meter, mounted on one axis. All of these cutting attachments are fixed in a specific order and at different angles in more than one row, which provides a significant deepening into the soil.

The discs themselves are straight and cup-shaped. Cups have a more complex configuration and are designed to turn over the earth when sowing seeds or potatoes early.

The edges of the discs are made uneven to better cut the soil and reduce resistance with the soil layer. At the same time, the layer rises and falls, which contributes to its crushing and breaking into small particles.

Disc harrows are the least susceptible of all types of soil and plant debris. Consequently, they do not require constant cleaning for a long period, which saves time and effort.

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 machine owners do tiller harrowing with square tine implements, although round or knife tines are also sometimes used.

You can attach such a harrow to the tiller by connecting it to the frame. For this, hinges or a spring strut are used. Farmers often use a tiller harrow. which is fixed 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.

How to make a harrow for a tiller with your own hands

In order to increase the yield in the field, they always plowed and harrowed the soil. Our ancestors did this, and modern agrarians do the same.

But in order to do this work, in the old days they harnessed horses, and today the harrow is attached to tillers (for small farm plots, private summer cottages) or to a tractor (this is for large farms in large areas).

Based on the foregoing, a do-it-yourself harrow for a tiller is an important tool for any summer resident, below we will take a closer look at the manufacturing process and how to do the correct harrowing with a tiller.

Homemade tiller harrows

It is much more pleasant if the harrow for the tiller is made by hand. So, today we will tell you how to make a harrow yourself.

The following types of harrows are used for tillers:

  • rotary,
  • dental,
  • cutter.

The rotary harrow effectively removes the topsoil. The working depth can be adjusted from 4 to 8 centimeters. The harrow width is a very important factor that affects the speed of cultivating the land in the garden. Obviously, the larger the harrow, the more power the tiller should be. Rotary harrows have drums with sharp metal strips (see video), which are installed at an angle. over, this harrow allows you to remove plant residues from the soil.

How to make a harrow for a tiller with your own hands

The harrow is a tiller attachment that helps you to work the soil better, which means it increases yields. Previously, the harrow was pulled by horses. Today the harrow is attached to a mini tractor or tiller. This is why the tiller is an essential technique for every farmer.

DIY harrow for a tiller: drawings

Homemade construction drawing

The disc harrow does the same job, only the design is different. Here the working tool is discs that are mounted separately on special racks.
The tine harrow has tines that are equally spaced on the same structure. Teeth are usually up to 30 centimeters long.

So, before you make your own harrow, you need to decide on the design features, and also study the drawings.

The harrow is very simple. This is a metal frame that has a tiller mount. To make repairs easy, the teeth do not need to be welded, but bolted.

Disc harrow

It is an active harrow. It is better to use this tool with cultivator type tillers. on traction ones you will have to design a power take-off shaft. Soil cultivation is carried out by cutting through it with rotating discs.

Discs can be straight, rotated at different angles with respect to the axis of rotation, or cup-shaped. Cups are more difficult to manufacture, but they allow you to wrap the seam. thereby taking on part of the plowing functions. Such discs are perfect for seeding green manure or shallow early plowing before weeds emerge when sowing potatoes or cereals early.

You may be interested in a do-it-yourself potato digger for a tiller.

The edge of the disks is usually made of an uneven shape in order for them to cut the soil more easily when plowing, to experience less resistance when rotating within the seam.

Design

Tiller harrow drawing

The harrow is a grid to which the teeth are rigidly welded or bolted. In the front part it has a hitch. usually a hitch with holes, which is inserted into the towbar pipe of the tiller and then fixed with a pin. A chain must be welded between it and the hitch. without this, the work will be very hard for the plowman.

The grill must be strong enough. It can be made from square or plumbing pipes and corners. The thickness of the metal must be at least 3-4 mm, otherwise the teeth welded to the thin-walled pipe will break out during operation together with the pipe metal.

The lattice structure can be in the form of a cage, consisting of longitudinal and transverse elements. But a lattice is better suited, in which the “rods” are welded at an angle of 45 degrees to the direction of movement of the tiller. such a lattice will be less exposed to bending loads.

The size of the cell is selected in accordance with the location of the teeth. It is best to figure out in advance how your teeth will be located, and sketch this in the drawing, and then draw a lattice on top of them, to which they are attached. The size of the frame itself must be such that it does not interfere with driving and following the tiller.

The harrow frame must not extend beyond the tiller handles.

In this case, the dimensions of the coupling must be taken into account. You don’t need to make a grille too wide. the tiller simply won’t pull more than 1 meter.

The teeth are best made from corrugated reinforcing steel with a diameter of 10 to 18 mm. The length of each tooth is from 10 to 20 cm. The height of the tiller’s hitch does not affect the height of the tooth. the harrow is attached with a chain. The longer the tooth, the thicker it should be. It is advisable to sharpen the teeth before installation and be sure to harden, because non-hardened teeth will bend during operation. On light soils, you can use a harrow with not sharpened tines.

The frequency of their location should be no less than every 10 cm. if done less often, harrowing will be ineffective. It is allowed to put teeth with a slight offset across the row, so that they can be conveniently welded and they provide the required processing intensity. At the same time, it is necessary to calculate that their resistance is directed symmetrically to the thrust axis, otherwise the tiller will “wag” and it will be impossible for them to harrow.

Harrow types

Harrows are subdivided into the following types:

  • Dental
  • Disk
  • Rotary

Tooth harrow

The tooth harrow is the oldest known to man. It consists of several rows of teeth that pass along the soil during processing, loosening and leveling it. They differ in the number of teeth. for a tiller, a wide one is most often used, in which the teeth are located in three to four rows and often.

do-it-yourself, disc, harrow, tiller

It is most rational to use it with traction type tillers, for example, Neva or MTZ. These tillers are capable of developing significant longitudinal force and have increased traction with the soil required for work.

A subspecies of a toothed harrow is a spring harrow, which is often used when processing an agricultural plot with a tractor. When working with a tiller, springs instead of teeth will reduce their number and size, they also rarely break.

Rotary harrow

Such a harrow is somewhat reminiscent of both a cultivator and a disc harrow. Both it and the cultivator have rotating toothed parts that cut into the ground and overturn small parts of it. It differs from a cultivator in a shallow working depth and a large number of working teeth. Unlike the disc, the rotary harrow discs are always at right angles to the axis of rotation.

The teeth of the active rotor have a special bend, depending on the radius of the disc itself and the coefficient of adhesion to the soil of the wheels of the tiller. the more slip, the more the tooth should be bent. When working, they pierce the soil at right angles, thereby providing aeration. When exiting, such a tooth slightly pushes the soil, pulling out small weeds that did not have time to take deep roots.

The work of an active rotary harrow is possible even after the emergence of plant shoots. it does not injure large plants and practically does not damage them. Its use allows you to save on mineral and organic fertilizers. due to aeration, substances are actively absorbed from the air. It also promotes root growth.

How to make a harrow for a tiller with your own hands according to a drawing: we illuminate all the nuances

The first devices for harrowing have appeared since the time when man first learned to work the land with a primitive wooden plow (plow). The harrows were also made of wood and were not very long for greater maneuverability, but heavy enough to crush large clods of earth formed after plowing.

Homemade classic (tooth) tiller harrow

For a long time, tractors have changed horses, and harrows have become more advanced and efficient, and can be installed not only on heavy and medium agricultural equipment, but also on mini-tractors and tillers. This type of equipment allows not only breaking up large clods and covering the soil to retain moisture, but also collecting the remnants of dry vegetation, as well as removing its roots.

There are the following types of harrows:

  • dental or classic;
  • rotary or rotary;
  • disk.

Homemade tiller tooth harrow

It is easiest to make with your own hands. For this, it will be enough to have materials, an angle grinder and a welding inverter. Allows for pre-planting loosening of the soil and incorporation of small seed. It is not an active harrow and is suitable for working with a traction tiller.

Traditional harrow

The classic, or as it is also called, horse harrow, is used to create an even and loose surface. Also, this type of attachment allows you to efficiently cover moisture in the soil and thereby prevent it from drying out. The harrow crushes large clods of soil to the required fraction, destroys weeds and removes vegetation residues from the soil. The equipment is quite light and therefore is used for shallow soil cultivation, crushing clods of soil and shallow loosening before sowing.

HOME MADE DISK HARROW

The factory-made tiller harrow is made of special structural steel that can withstand significant loads. Also, this equipment evens the soil well after milling.

This type of harrowing equipment is a straight or zigzag frame that you can make with your own hands from a steel strip, a square pipe or angle, a tiller hitch stand and teeth. You can fix the teeth on the frame by welding, or by cutting a thread on them, fix it with nuts. The working bodies on the frame are located at an even distance from each other, and their length can be 25-45 mm. Regarding the width of the equipment, for example, 500-600 mm will be enough for the Neva tiller. The video presented shows the tooth harrow in operation.

You can also make a motor-block tooth harrow with your own hands and according to the drawing below. It will take half a day to make such attachments, but it’s worth it.

In order to make such equipment for a tiller, we need the following:

  • weld iron strips to a square metal pipe, onto which, in fact, teeth with a thread cut on one side will be attached with the help of nuts;
  • the drawbar of our attachment ends with a welded bushing, through which a connection with the used tiller will take place with the help of a metal pin;
  • we make a stand with an adjusting screw for adjusting the lifting height of the harrowing device to ensure uniform penetration of the working bodies into the soil.

Purchased factory equipment, though homemade harrow, to tiller “Neva”, there is a feature of the accumulation of wet soil with residues of vegetation on the working bodies, as a result of which the tillage may become ineffective. In order to easily and easily clean the teeth with a scraper or any metal object, we use the lifting lever of the unit.

The video shows the simplest tiller tooth harrow with dimensions.

Tiller tooth harrow

The tine harrow has a simple design, but it is necessary for harrowing the surface of milled and graded soil immediately before planting crops. The phrase “Everything that is simple is brilliant” perfectly describes how the tine harrow works. A tine harrow is, in fact, a large rake with several rows and many teeth, which, using a tiller, crush and level the ground in its path. But the primitiveness of the soil cultivation process with this device does not in any way affect the efficiency of the harrow.

Cultivating with a Perfecta

Making a disc harrow for a tiller: what is needed for this

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

  • 8 spherical / cup-shaped / star-shaped discs with a diameter of 445 mm and a metal thickness of 4-5 mm, to reduce the resistance of the soil around the circumference of the disc, you can make cutouts of the angle grinder at your discretion;
  • frame 1400×650 mm from a 45×45 mm profile pipe with a wall thickness of 4-5 mm;
  • a rod 1500 mm long and 50 mm thick, on which the discs will be placed;
  • two bearings with attachments for a rod with a diameter of 50 mm.

Tiller tine harrow preparation and materials

The easiest way, of course, would be to adapt a manual tooth harrow for a tiller, which is driven by human or horse traction, but if there is none, then we will start from the very beginning. And in the beginning, you will need to acquire the tools that you will need to make a tooth harrow for a tiller yourself, and these are:

  • welding machine;
  • angle grinder with discs for metal;
  • chains for attaching to the tiller;
  • strips, pipes, channels, beams;
  • corners with a metal thickness of 3-4 mm;
  • pieces of reinforcement or bolts 15-20 cm long and 1-2 cm thick with one pointed end as harrow tines.

Hitching the tine harrow and tiller

The extreme links of the chain are welded to the orientation center for applying the force of the finished harrow, the other end of which is bolted to the hitch or by welding. It is important that the resistance of the harrow teeth is directed symmetrically to the thrust axis, otherwise the harrow will be pulled to the side and it will not “bite” into the ground and perform its function. It is necessary to check if the harrow is sideways and, if necessary, change the attachment point of the hitch to the harrow.

Due to the simplicity and reliability of the design, if necessary, you can attach weights of different sizes and shapes to the tine harrow.

Tiller Disc Harrow Assembly Process

The rod is threaded through the center holes of the discs and holes in the frame so that it is centered and parallel to the sides of the frame. The discs and the bar must be fastened with a welding machine. The ends of the boom are fixed in bearings, which, in turn, are fixed on the outside of the harrow frame in such a way that the entire boom, together with the discs, will rotate during movement. The harrow discs should be in contact with the surface and the sharper the angle of attack on the surface, the more efficiently the harrowing process will be. The entire harrow structure is attached to the tiller frame both by rigid coupling and on the harness. If you make this device in smaller proportions, then you can make 2 disc harrows that will work the land at the same time at different angles.

How to make a harrow for a tiller with your own hands

a tiller is the main labor and multifunctional unit in your household, because one tiller with sufficient imagination and skill of the user can, if not do, then for the most part, facilitate any production task. But a tiller, like a person, needs the appropriate tools to complete a particular task, and, as we know, there are an abundant number of varieties and forms of them. There are several types of harrows alone.

Harrowing milled land is an important step in cultivating the land before planting seeds, seedlings or tubers in it and has the following practical goals:

  • leveling the surface of the earth;
  • destruction of clods;
  • softening the soil surface, simplifying the process of planting, sowing, maintaining moisture in the ground;
  • improving the assimilation of organic and mineral fertilizers;
  • cleaning the surface from plant residues and destruction of weed shoots.

For all this, mankind invented a harrow, which evolved from a tree trunk with rigid branches into 3 modern types of harrows: a tooth harrow, a disc harrow and a rotary harrow. Therefore, in this article we will try to tell you how you can save on buying a harrow for a tiller by making it yourself.

Disc harrow for tiller

The disc harrow is used to loosen soil up to 10 cm deep with a hard dried crust in order to soften it, incorporate green manure, early shallow plowing before weeds emerge for sowing grain.

The disc harrow has a more complex design, in comparison with the device of the tooth harrow, since it has rotating elements, on the operation of which the overall result depends. The result is also influenced by the angle of impact of the harrow discs on the soil surface. The overall harrow design can be supplemented with shock-absorbing suspension and traction that adjusts the angle of inclination of the discs.
