Do-it-yourself cutters for the tiller

Do I need to sharpen the cutters on the tiller?

do-it-yourself, cutters, tiller

All soil mills are self-sharpening tools. Sharpening is not needed for them, as it can only spoil the structure. Only in some cases, if you have been using the cutter for a very long time and you see that it has begun to work the land poorly, you can sharpen the knives.

The rotary tiller is an important element of every machine. Homemade properly assembled cutters can be used on any modern tillers, in particular on the Neva MB 1 and MB 2, MTZ and others. Such designs will aid in the cultivation of the land and make it easier to carry out agricultural tasks..

Saber cutter and its assembly

Before assembling the cutters on the tiller, you need to understand well the concept of a motor cultivator. This is a welded frame made of pipes with a diameter of at least 23 mm with a fuel tank and an engine installed on it. They are fixed to the frame with brackets. The engine is otherwise called the power unit. It is equipped with a gearbox and clutch mechanism. Each cultivator brand has its own power unit with different power.

Most often, the cutter has a saber shape. Such a scheme is the most popular these days, therefore it is also called standard. The effectiveness of saber knives has been proven for many years of use on soils of different composition. Installing such cutters on a tiller allows you to perform a lot of work. The strength of knives made from carbon steel is very high. The cutter design is collapsible. Each knife is heat-hardened by high-frequency currents during the manufacturing process..

How are the tiller cutters assembled? Any milling cutter consists of 2 blocks. Each of them contains 12 cutters. The block consists of 3 nodes. Each node is 4 legs at right angles (image # 3). They are located at an angle of 30 ° relative to each other. Each knife is made of 5mm thick steel. They are attached to the post, which is made of a corner measuring 63×40 mm. The other end of the post is welded to the flange so that 4 knives are joined together. All parts of the cutter are connected to each other with bolts, washers and flanges. This design is very reliable. She is able to withstand quite high loads. If the cultivator is going to be used constantly, it is better to install a factory-made cutter.

In the process of installing the cutter on the tiller, some craftsmen have difficulties. Therefore, it is recommended that you do this work together. The assembly is usually carried out on specially made wooden tragus with a height of about 50 cm. They help to cope with the work faster. the tiller rests neatly on the coulter and tilts about 45 °. Tragus is placed under the steering handle. In this position, the wheels are removed from the tiller and the cutters are installed (image No. 4). On the outer ends on the right and left, you need to install the plates on the tiller cutters. They improve the performance of the unit, make it run more stable and smoother..


The milling cutter belongs to attachments. It can be removed and installed. It affects the quality of cultivation of any type of soil in the garden and vegetable garden. The high-quality operation of the engine also largely depends on the quality and condition of the cutter..

It is quite possible to assemble the milling cutter on the tiller yourself.

If you harvest and sharpen it correctly, you can loosen the soil and remove weeds from it very quickly. How to assemble the cutter correctly? You need to make good knives. This is the backbone of any type of cutter. It is the knives that are designed to cope with weeds, loosen the ground, distribute fertilizers in the soil..

There are several types of this attachment, but the most common are saber-shaped specimens and crow’s feet. With their help, most of the work on the site is performed. At the ends of the structure, plates are installed on the tiller cutters. When working, they give a special smoothness of movement and do not allow the cultivator to dig deep into the ground.

Equipment such as a milling cutter is essential for any tiller, as it can be used to carry out most of the work related to soil cultivation. Basically, the rotary tiller comes with the unit, but in cases where you need to change the width and depth of processing, you should purchase the equipment separately.

Additional cutters allow you to increase the functionality of the tiller and simplify the work with it. Experts recommend having several pairs of cutters in your arsenal..

Saber cutter for tiller

The most popular and versatile models that are effective in a variety of earthworks. These models use the optimal shape of the knives, for the manufacture of which manufacturers choose high quality durable steel.

The models have a collapsible design, so their installation and maintenance is as simple as possible.

Varieties of cutters for tiller

Tiller cutters can differ from each other in shape and design, the number of knives and their location. They are installed at the rear of motor vehicles and depend on the power take-off shaft. Tillers give the best results when the driving speed is increased..

The general device of the cutter can be described as a set of tillage blade knives placed at different angles on the blades, welded or fixed with fasteners to a rotating axis.

The blades smoothly and alternately enter the soil, which has a beneficial effect on the tiller’s transmission.

There are 2 types of cutters:

  • active, or saber-shaped;
  • crow’s feet.

Flat cutter

A do-it-yourself flat cutter for a tiller is made from a metal pipe with a diameter of 42 mm based on the drawings of individual elements. In the manufacture of blades, they are adjusted in size and bent at a given angle. With a welding machine, the blades are welded to the pipe. Sharpening of cutters is carried out in a fully assembled state. When assembling the module, it is necessary to dock them with the tiller hitch, during a test run, adjust.

Crow’s feet

The second constructive type of cutters is crow’s feet. The product got its name for the unusual shape of the cutting elements, reminiscent of the legs of a goose. They are triangular in shape and are located at the edges of the posts. The number of cutting elements and the size of this module also depend on the power of the tiller. The more racks with knives – the better the processing.

This cutter is capable of processing heavy virgin and clayey soils, but in areas with increased vegetation and roots, the product is likely to clog.

The principle of operation and structure of the tiller cutter

Almost every farmer dreams of the presence of a motor-cultivator with a milling cutter on the farm (she is a soil cutter, she is also a cutter for a tiller). With the help of soil cutters, you can perform a wide range of work on the site at any time of the year.

A modern range of technical equipment to facilitate agricultural work allows you to find the best options to minimize effort to achieve the best results.

1.1 Differences in the design of soil cutters

Tillers have a different design, which allows you to attach them to different equipment and use for different purposes.

  • attachments;
  • trailed equipment;
  • material and form of manufacture of cutting parts of the cutter (knives);
  • complete set with additional discs for plant protection;
  • width and depth of tillage depending on the type of construction.

For the tiller, the cutter can be purchased as a set or separately. The versatility and simplicity of this equipment provides ample opportunities in combining available tools and options. Up to the point that a tiller for a tiller, like the tiller itself, can be assembled with your own hands.

1.3 Do-it-yourself cutter for a tiller

First, let’s find out the difference between the two types of cutter knives:

  • crow’s feet knives;
  • saber knives.

The crow’s feet variant is a relatively new model of knives that has proven itself well on particularly difficult and hard soils. Due to the non-separable design, a certain margin of safety of the cutter is achieved, but there is also a drawback. The knives are often clogged with weeds, so either they have to be constantly cleaned or use such a tiller cutter on relatively clean ground.

Milling cutters for tiller “Hound’s feet

Reciprocating knives are a kind of generally accepted standard for a tiller cutter, the knives of which are made of high-strength steel. The design of the model is collapsible, but the alloy is absolutely not suitable for welding.

The assembly of the tiller cutter begins with the selection of the drawing. Special attention must be paid to ensure that the “active” part of the soil cutter is assembled with minimal deviations from the original technical requirements..

This will save you from further problems at work. An improperly assembled or installed unit can disrupt the running axis of the cultivator and it will “drive” from side to side, which will negatively affect, at least, the aesthetic appearance of your garden or field.

The advantage of making your own soil cutter is that you can adapt it to the specific needs of your site. So, armed with an angle grinder and a welding machine, taking out the required number of parts, making a little effort and showing ingenuity, you become the proud owner of the knowledge of how to assemble a cutter on a tiller.

2 DIY tiller

We figured out a little with the manufacture of soil cutters. Now, let’s look at the principles of building a motor cultivator..

It is not difficult to assemble your own tiller if it is clearly understood that a tiller or a motorized cultivator is a unit that combines the functions of a plow and a tractor. From the plow there are handles with buttons and switches, from the tractor – the front functional part with the engine and wheels.

For self-made tillers, people are increasingly using out-of-order motorcycles, motors are taken from old chainsaws, wheels and springs – from obsolete technology. There are many variations. One of the most popular models is the tiller Arkhipova. This is a two-wheeled self-propelled gun with an engine from a scooter and control levers for clutch and gears from a motorcycle..

The cultivator can be made both on a gasoline engine and on an electric one. The required set of tools will mainly be:

  • circular knives for cutting and subsequent grinding of metal;
  • welding machine;
  • drill;
  • spanners of the required diameter.

Then we resolve issues with details. The first of which will be the selection of the transmission. It must be such as to generate high torque while maintaining low speed. Then we cook the frame from pipes and steel corners, and from a pair of side members with a beam – a swivel mechanism. Then we consider the issue of equipping the motor with a cooling system, preferably a forced one. Considering the air purification system and the exhaust system.

tiller do it yourself

The range of used equipment that can be easily installed as parts for chillers is unusually wide. Cut axle shafts from the rear axle of old “Zhiguli”, an adapter from the steering columns of cars or trucks, with an engine from a motorcycle, with a gearbox from “Zaporozhets”.

And this is not the whole list of options available for use and application. Human genius knows no boundaries. Do you have your own options for solving such problems? Share, discuss.


Self-installation of cutters on the tiller

Self-installation of equipment on the tiller is performed in exactly the same way, both for saber cutters and for devices of the “crow’s feet” type..

In any case, the procedure is as follows:

  • Place the manufactured cutters on a special wooden “goat”, about 0.5 m high;
  • Gently tilt the tiller at a 45 ° angle and rest it on the coulter;
  • Place the “tragus” under the tiller’s rudder grip;
  • Dismantle the standard wheels of the agricultural machine, and install homemade cutters instead;
  • Securely attach the cutter discs to the left and right outer ends of the cutters – they will significantly improve the travel of the tiller with cutters and make it smoother and more stable.

After completing all the above steps, you can start processing the soil. During work, do not forget to monitor the reliability of the fastening of the plates, fixing the main and additional cutters on the tiller.

How to assemble correctly cutters on a tiller – making saber equipment

Immediately before making saber-shaped rotor devices, we advise you to study the drawings that will tell you the correct procedure for assembling equipment..

Any saber cutter for tiller consists of two interconnected blocks, each of which contains 12 cutters. The design of one separate unit includes 3 units, each of which is equipped with 4 cutting knives. The latter, in turn, are located in relation to 30 ° in relation to each other. The assembly of saber-shaped devices is as follows:

  • First, make a stand using a 6.3 × 4 cm corner;
  • Weld one of the ends of the rack to the flange so that later you can combine 4 cutting knives with each other;
  • Connect all cutting elements of the cutter to each other by means of flanges and bolts with washers.

A rotary milling cutter manufactured in this way has high strength and stability, which will allow you to use it for processing soils of any density.

Which cutters are best for the tiller – we decide on the choice

Many novice farmers find it quite difficult to decide on the right cutters for the job. In fact, there is nothing difficult about this – you just need to study and compare the qualities and characteristics of different types of equipment. The cutters available on the market are divided into 2 types:

  • saber cutters – attachments of this type are in the highest demand, these cutters are included in the delivery set of many tillers. Among the main reasons for the popularity of mills of this type should be highlighted the highest efficiency, the ability to cultivate any soil, including that previously untouched by agricultural machinery. High-quality models of saber cutters are made in 2 stages: first, products of increased strength are formed from carbon steel. At the next stage of production, knives are subject to prolonged heat treatment under the influence of high-frequency currents. The main feature of high-quality saber-shaped devices is the impossibility of welding cutting surfaces;
  • cutters “crow’s feet” – equipment of this type appeared on the market relatively recently. In practice, hard soil lends itself to processing with such devices. free of hard weeds. The high efficiency of these cutters is achieved due to their specific shape. The latter also allows you not to harm the roots of the planted plants during the cultivation of the garden. Among the main disadvantages of this kind of devices, one should highlight their low strength and a lot of inconveniences during repair..

When buying any of these types of cutters, be sure to consider the type of soil to be processed before and after planting..

Homemade milling cutters for tiller – the procedure for manufacturing equipment

The simple design of cutters for tillers allows you to make such devices with your own hands. Below we will consider the correct procedure for the manufacture of different types of equipment for plowing the soil..

Manufacturing of cutters “crow’s feet”

Immediately before assembling this type of fixture, you will need to carefully prepare for work. With tools and materials you will need:

  • steel pipe, 4.2 cm in diameter;
  • steel plates for making cutting knives;
  • welding machine;
  • angle grinder with disc set.

The active crow’s feet cutter is assembled in the following order:

  • For the manufacture of cutting elements, you can use the springs from the car. Cut them into equal pieces, and then weld them to a steel pipe that plays the role of a base;
  • Sharpen the edges of the cutting elements and weld them to the base used;
  • After assembling the equipment, start it and make the necessary settings. At the same time, keep in mind that after starting the tiller, the knives of the equipment should hang in the air and not touch the ground..

In order for the crow’s feet cutter to last as long as possible, it must be slowly lowered to the ground. Otherwise, the equipment may break..

Tiller cutters

Milling cutters are one of the most commonly used types of equipment for tillers. It is quite difficult to overestimate the role of milling cutters in agriculture, because these devices allow you to process the soil with high quality and fully prepare it for further planting with a minimum amount of time from the efforts of the farmer..

Do I need to sharpen the cutters on the tiller – we figure it out together

It is rather difficult to give an unambiguous answer to this question due to several factors. First, the recommendations of the milling cutter manufacturer are of great importance. Some companies that produce high quality plowing equipment do not advise sharpening cutting elements, as this will reduce the efficiency of the cutters and void the warranty for their service. Other manufacturers, on the contrary, recommend that the cutters be sharpened before each season of the tiller’s operation..

The second important factor is the result that the sharpening of the cutters can bring. The only, but very important advantage that this procedure gives is ease in the cultivation process, because it will be much easier for sharpened cutting knives to go deep into the ground and plow it effectively. The disadvantages of sharpening include the need to dismantle and install the equipment on the tiller every time. Another very important drawback is the ability of cutters to grind weed roots deeply hidden in the ground, which will lead to their intensive vegetative reproduction throughout the entire area of ​​the garden..

The third factor is the type of soil being cultivated. If a rotary tiller on a tiller is used mainly for the processing of hard clay soils and virgin lands, then sharpening the cutting knives will help to plow such soil faster and better. If the soil in the garden is soft, then, as a rule, it is not necessary to sharpen the set of cutters used..

All of the listed advice on the manufacture, installation and sharpening of devices are suitable for the operation of equipment in tandem with the Neva MB-1, MB-2 tillers, as well as agricultural machines of the MTZ, Celina brands and units of other imported and domestic manufacturers.
