Homemade mower for a mini tractor: save money. Homemade rotary mower: step by step instructions Homemade mower for a mini tractor
Many farmers, people involved in farming, have to deal with the preparation of feed for livestock. In order to mow the grass, you need a mower. A modern mower for a walk-behind tractor is expensive. Therefore, craftsmen adapt to make mowers on their own, from improvised means. It's cheap. And the moral satisfaction received from such work is important. Especially prefer to do rotary mower. It is not too difficult to perform.
Types of mowers and what you need to make them
Mowers according to their device are divided into two main types and one additional type. The main ones include:
- rotary;
- segment.
An additional type is considered a mower on a platform. It can be in any design: both rotary and segmental. Unlike conventional rotary and conventional segment mowers, the mower on the platform is mounted on the frame, in the center. By the way, working with such a mower is more efficient and reliable.
In order to make a mower, first of all, you need materials. Approximately these:
- all kinds of metal blanks in the form of squares, tubes, plates, sheets;
- pulleys for belts;
- transmission belts;
- gears;
- bearings of the required size.
All kinds of materials are used. All kinds of mowers are coming up.
Rotary mower for mini tractor It is carried out both according to our own drawings, and according to ready-made ones. Fortunately, the Internet is full various descriptions and drawings how to make them. Choose any type of mower, and do it. According to your needs and possibilities. Still need some tools to get the job done. Namely:
- vise;
- hammer;
- sledgehammer;
- welding machine;
- all sorts of auxiliary tools.
Tools must be in good condition. It would also be desirable to have emery machine with abrasives drilling machine or at least a drill, and the so-called "grinder". The possession of these units and tools will greatly facilitate the creation of a do-it-yourself mower.
How to make a mower on your own
Here is one of these units in real performance:
The picture shows that the working tool of the mower is two disks located horizontally below. Small discs are welded to metal discs. sharp knives in the form of sharp strips of metal along the edges of the disks. As the discs rotate, the knives cut tall grass. The rotary mower will not be able to cut low grass. Such a feature of this mechanism. But the main thing for the villagers and farmers is the preparation of fodder. For these purposes, such a mower is just right.
As you can see, to create a rotary mower, you need to try. There are many nuances that need to be taken into account. Disc blades and the discs themselves must be positioned so that the disc blades do not touch each other. And at the same time swath coverage was respected. Pay attention to how the disks in this picture have knives. When one blade of one blade is in one position, the closely spaced blade of the other blade is in a different position. This positioning device allows you to mow the space with grass between both rotating planes.
The discs must be placed on axles with closed bearings so that grass does not get into the bearings. The axles are attached to the central shaft, which connects them with the help of two reduction gears to the shafts of the disc axles. These types of reduction gears have two bevel gears inside the box. To convey the rotation of two converging shafts at an angle of 90%. Central shaft with two gears open type receives torque from the belt pulley (right). The belt transmits rotation from a working walk-behind tractor to the central shaft. The whole unit is attached in the center to the walk-behind tractor.
Also, for all rotary-type mowers, it is necessary to weld or bolt onto the bolts of the unit on the sides of the guide slide to capture the grass. It is very important. So that the grass, falling between the sleds, could not avoid the knives. Mowing becomes efficient.
In addition to the above mechanism for implementing a rotary mower, people come up with all sorts of others. Here is one of them:
It also has grass-to-disc lugs to grab the grass. Only the discs here are driven by a belt drive from a small electric motor located directly on the mower frame.
How to make a segment mower
To create such a mechanism, it is easiest to find on old mowers that have failed (among scrap metal) preserved working parts with teeth for cutting grass. Here is one of the drawings for creating such a mower.
This is a blueprint for creating a mower with gasoline engine mounted directly on the mower frame. Even if the unit is made differently, the working part of the segment mower still looks like this:
The principle of mowing the grass here is the consistent rapid movement of the cutting part of the mower to the right - to the left. This is achieved through a connecting rod rotation transmission device, like this, for example, in this picture:
Here is a chain drive from bicycle sprockets. A connecting rod is welded on the lower sprocket, which, when the sprocket rotates, sets the mower blades in motion.
Here is another homemade mower, made carefully, with great skill:
Here, a belt drive from a shaft is used, which is connected to another shaft with a coupling joint, going to the source of rotation of the walk-behind tractor. The whole unit is suspended from the walk-behind tractor on a reinforced suspension.
Platform mowers
If you install a segment mower for tractor in the center, and not on the side, you get a mower on a platform. Approximately like this:
In the picture, the mower is not yet ready. If you add a transmission transmission mechanism here, it will be ready.
The rotary mower type on the platform can be made according to this drawing:
There would be a desire. Everything can be done. For those interested, links to the video:
The mower for a mini-tractor can be rotary or segmented. The first option is very popular with farmers, so a home-made rotary mower or a factory copy is often found in the fields.
This accessory is designed for mini tractors, whose power varies from 12 to 25 horsepower. Such devices will help to process fields ranging from 6 acres to several hectares. Consider the popular models of mowers and tell you how you can make this equipment with your own hands.
Varieties of mowers
All mowers that are presented on the agricultural equipment market are divided into rotary or segment. The difference between these units lies in the principle of their operation. 
Segment mowers are mainly used for landscaping. This equipment is very popular among utilities and landscape designers. The design consists of a movable knife and permanently installed sharpened plates. Segment mowers are cheaper and this is what attracts attention.
From the point of view of farmers, a rotary mower looks more profitable. It is used not only for cleaning wild grass but also agricultural crops. Rotary units are made in the form of a platform on which cutting discs. The necessary working force is transmitted from the diesel engine of the mini-tractor through the power take-off shaft.
Compared to segmented mowers, rotary units have more functionality. They not only mow the grass, but also form the bevel into swaths, stack the swaths and can adjust the height of the cut.
Given that the rotary mower is more popular, consider this particular type of attachment.
Mounting method
All mowers on the market differ not only in size and performance, they have different scheme fixtures for technology. The following categories can be distinguished:
- Semi-mounted. These models are equipped with their own pneumatic wheel. Thus, the load is distributed more evenly. Such a device is mounted on a mini-tractor using a bracket to the rear hitch. Responsible for lifting and lowering equipment hydraulic system.Suitable for cleaning grass in large areas.
- Mounted. This rotary mower is ideal for working on fields with complex geometry and terrain. The equipment is attached frontally, to the front hitch of the tractor. Does a good job of cutting grass small areas and steep slopes.
- Trailer. This equipment can be attached to any mini-tractor hydraulic outlet. For such models, at least three rotors are usually installed, which are located at the back. Used for harvesting crops over large areas.
- Grinders. These models are rarely used in agriculture. Their intended use is to improve the territory. The equipment is working following principle: mowed grass rises through the pipeline into a special chamber, where it is crushed to the required fraction.
Popular Models
On the agricultural equipment market, you can find mowers of Russian and foreign production. Let's start our review with a domestic manufacturer.
Agromak
This company produces rotary mowers KP-2.1M, KRR-1.9, KR-2.4. These products differ in processing width, performance and price.
From common specifications can be identified adjustable height cut. This figure can vary between 4-7 centimeters. It should be noted that only high-strength steel is used for the manufacture of cutting elements. This increases the wear resistance of the knives.
A fuse is provided to help protect the working mechanisms from damage. From interesting features it is possible to single out the conditioning and agitating rollers, which make the bevel easier and provide the blowing of the harvested grass.

Homemade rotary mower for a mini tractor
If you like to make various mechanisms with your own hands, then it will not be difficult to assemble a mower and install it on a mini-tractor. The easiest to make rotary variant. The device can be made even without drawings.
Before starting work, you will need all the iron junk that you can find. From the collected scrap metal, it is necessary to select strong bars or corners for the manufacture of the frame. Considering that the equipment will be installed on a mini-tractor, the length of the side should not exceed 40 centimeters.
Now you can begin to manufacture the working mechanism. For the manufacture of rotors, you can use two bottoms from iron barrels. Knives will be attached to these discs.
The cutting elements can be removed from the old peeler or made independently. The main thing is that the knives rotate freely. The knives are attached to the rotors with an axle. For the axle, you can use a piece of pipe with bearings pressed into it. The force required for operation is transmitted by means of a belt drive.
According to farmers, the resulting design provides a coverage width of 110 centimeters and good performance. For long service life all working elements are recommended to be closed with a special casing.
The unit is installed to the hitch of a mini-tractor; hydraulic cylinders will be needed to raise and lower the equipment.
Today, the variety of equipment that belongs to the agricultural direction never ceases to amaze each of us. Undoubtedly, the main activity of each of them is the facilitation of human labor in relation to agricultural work.
After all, we all know how difficult it was for our ancestors, who, in order to simply feed themselves and their families, spent whole days in the fields in order to bring their land into proper shape and therefore collect good harvest, and a lot of effort was spent on this, because they worked with the help of hand tools.
Fortunately, it is much easier for us now, because technologies are developing daily and have raised us to fairly high heights. All that is required of us is to sit comfortably behind the wheel and simply control the tool that will do all the work for a person. Undoubtedly, there are a great many units that are ready to help us in this difficult matter, and it's up to you to decide.
Therefore, it can be said without exaggeration that the progress of the technical direction fully meets all the requirements for tools.
Actually, we will talk about one of them in this article, namely the rotary mower, which today is very popular among landowners. You can learn about the principle of its work and about aspects of its device.
Moreover, given that this kind of tool is quite expensive, let's say, not cheap, we will tell you how you can make this unit with your own hands. So, let's actually begin to consider this topic.
Principle of operation
First of all, it is worth noting that this kind of mechanism is intended for work that is performed in meadows and fields, namely, mowing. Moreover, it can be not only crops that are grown in the agricultural area, but also the device is quite easily and simply able to cope with weeds, which actually also overwhelm our fields.
For motoblock
In order to make this kind of tool yourself, you will need: chains taken from a chainsaw gearbox, discs in the amount of two pieces from a grain seeder. More detailed information on which oil to use to lubricate the chainsaw chain is contained in. To make the knives themselves, you need 65 g hardened metal. It is worth noting that each direct disk must have four knives.
An example of a homemade rotary mower in the photo.
For this type of installation, you must drill with a carbide drill on each individual disc a kind of hole, the diameter of which should not exceed 6 mm. The knives themselves can be attached using a special shank, in fact, it is installed on the coulter and it does not matter at all what mounts the knives will be installed with.
You must remember that the gap itself between the knife and the shank should not be more or less than 1-2 mm directly from the knife thickness. Moreover, keep in mind that the knife itself must be able to rotate 360 degrees.
Axial fasteners are made of durable carbon steel, their size should be equal to 8 mm. It is this axis that is tightened from the disk itself to the stop and at the same time the movement of the knives must be free. It is also worth noting that such a home-made mower is intended for the Neva walk-behind tractor, you can find more detailed information .

For tractor MTZ
Thanks to this kind of device, you can, without any problems, not only mow the grass itself, but also grind it. In order to make this unit with your own hands, you must actually know what this kind of home-made mower consists of. So, its components:
- A shaft with chopper knives, the number of which is twenty-four pieces;
- Cheeks that are translated to the shaft itself;
- Knives that can be made directly from spring steel. It is important to remember that the edges located on them must be extremely sharp. For them, you need to make a kind of axis of dimensions of 9 mm.
It is important to remember that such a homemade rotary mower for t 25 is also great and the aspects of its manufacture are no different.
In fact, rotary mowers have the same structure, the only difference is in the blade models and attachment. are detailed in this article.
Safety
You must remember that:
- it is necessary to control the loads permissible precisely on the mass itself and the axle;
- in order to avoid any unforeseen situations is best use a tractor that has a cab;
- before starting this device first you need to transfer the mechanism to the position of the transport direction;
- you must remember that in no case should any unauthorized persons be in the driver's cab during work;
- moreover categorically Do not transport the device if it is not secured, or enabled;
- remember that if the unit is in a kind of transport position, then in no way can the selective shaft be turned on, which is responsible for the tractor power;
- before each start of operation of the device, without fail, you must check that all parts are tightened and installed;
- if you need to change the oil, lining or simply clean the mower itself, without fail you need to stop the vehicle first and actually turn off the cardan shaft;
- until the parts of the rotary mower have completely stopped, in no case should you approach it;
- when working with the mower, do not wear wide clothing, as purely by chance, its folds can get on the device, which can actually cause an accident;
- besides, it is impossible that during the operation of the device there were animals or strangers nearby.
conclusions
In this article, you had the opportunity to learn how you can make a rotary mower with your own hands. In fact, as you yourself saw, it is especially difficult to this process there is nothing, so with this kind of manipulation even a non-professional can easily handle it. However, if you do not want to take risks and start small, we bring to your attention.
The most important thing in the manufacture of a rotary mower is that you carefully repel our advice regarding both manufacture and safety.
The cutting element is located on a support wheel attached to a frame made of metal. When the process starts, the wheel begins to move, which entails the movement of the knife. Due to this, mowing occurs. Three cutting mechanisms can be attached to the wheel at the same time.
Such devices are highly productive. These units are used when working with large areas. When choosing a scythe, an important step is the speed of work, the height of the cut of vegetation and productivity. The rotary mower on a tractor is used for mowing wild and cultivated plants. Subdivided into:
- put the grass in a roller after mowing;
- folded into a slope;
- crush grass.
Drum mowers are used in farming. They are able to work in wet weather on any type of soil. Differ in durability and quality. Used when cleaning on roadsides and slopes. Able to cope with vegetation in places inaccessible to the tractor.
The mulcher is designed for post-harvest crushing and uniform distribution of mowing residues of grain grasses, corn, sunflower over the ground. Crushed into small pieces, the remains fertilize the soil and supply it with oxygen. As a result, the quality of the land improves.
Manipulators successfully cope with their task on slopes and roadsides.
The lawn mower minitractor cleans vegetation in areas inaccessible to the tractor. Used as a brush cutter.
A self-propelled machine is convenient for mowing independently (without a tractor). Are divided into:
- gasoline;
- electrical;
- accumulator.
Gasoline refuels with gasoline and performs work without being tied to a power source. Electric ones cannot work over large areas, since a power source is needed. Rechargeable is the most profitable, does not require refueling and mains power.
All three types of self-propelled devices designed for private households or small organizations, as productivity does not allow mowing on large territories. The mower has small weight and dimensions that allows to provide compact storage. Cannot be used as a rotary brush cutter.
1.2 Tractors for mowers
Depending on the power, boom reach, type of scythe drive, the parameters of a compatible tractor are determined. Important parameters when choosing a tractor: implement width, counterweight on the implement. Devices may fit various types tractors: for a garden tractor, T 16, MTZ, minitractor.
Such devices are produced by both domestic and imported manufacturers. Rotary mowers are suitable for these types of tractors. Main focus suitable for agriculture and private households. I grind the grass, mow it and ram it into shafts, grind it (evenly distribute it over the ground, which provides additional oxygen supply and soil fertilizer).
Mowing the grass with a tractor rotary disc mower is fast due to the high performance, Therefore, this type is popular with farmers. This model is convenient for working on rough, uneven, clogged surfaces. Also, the finished design can be replaced by a homemade mower for a tractor.
Since the design of such devices is quite light, you can make a mower for a tractor or a mini tractor with your own hands, having previously studied detailed information about her device.
Homemade rotary mowers are not inferior in power to factory ones. A homemade mower for a mini tractor differs only appearance. Such a homemade product is safe subject to safety precautions.
Rotary mowers are suitable for mini tractors. A representative of such machines are mowers for mini tractors Uralets. Differs in small weight (140 kilograms). Popular rotary mower kr 09 to the minitractor lateral, which is suitable for models Centaur, Dobrynya, and others.
2.1
The advantage is ease of use, performance, budget. Copes with grass on slopes, hills and other irregularities. Used as a garden tractor, lawn mower or brush cutter. Which is very beneficial, since there is no need to have a special brush cutter.
2.2 Scythe for tractors T 16
Finger mowers are suitable for these types of machines. Mowing self-sown and cultivated grasses with subsequent laying in raised. It is used in all climatic zones. Tractors with mowers are connected simply and quickly, which provides convenience when changing attached equipment.
For processing large areas, rotary mowers for tractors are popular. They are reliable, functional and easy to use machines.
Unfortunately, most owners of motoblocks and mini tractors do not always use them in full, and in order to mow a lawn or field, they hire other equipment. Although, it is quite possible to do this with a rotary mower. The cost of such a tool is prohibitively high, so it is much more profitable to build it yourself. We will consider how to make a rotary mower from improvised means further.
The principle of operation of the rotary mower
On modern market agricultural tools, there are a large number of different mowers. Rotary devices are the most popular. Due to their design, they have high performance and are easy to use both on a large tractor and on a walk-behind tractor.
The principle of operation of a rotary mower is to produce rotational movements in a rotor that has a round shape.
The rotary mower has the form of a rectangular bar, to which rotors with knives are attached. They are responsible for the correct cutting of plants.
Rotary mowers have gained great popularity due to their efficiency. The fact is that these devices use direct energy that comes from the tractor. Therefore, for their work it is not required to develop certain type energy. At the same time, productivity increases several times. These mowers are used in the process of mowing grass, weeds, fallen plants, they are called not only rotary, but also rotary.
When comparing a rotary mower with alternatives, then the first one has an efficiency of more than 70%, while the others have up to 40%.
The rotary mower is attached to a transport device, which is a tractor, mini tractor or walk-behind tractor.
There are three types of such mowers, these are devices:
- trailer type;
- semi-mounted type;
- hinged type.
Rotary mowers of the first type are attached to vehicles using a three-point scheme, so it is possible to adjust the angle of inclination of the device.
Mounted mowers are ideal for working on small plots of land. The use of semi-mounted devices is recommended for large areas, and trailed rotary mowers are used for working on uneven ground.
The rotary mower has a fairly wide scope. She perfectly mows the grass for its further laying in rollers. In addition, rotary mowers are distinguished, which not only mow the grass, but also chop and collect it. The principle of operation of such a device is to cut plants, feed them to special knives, which carry out grinding, transportation in a container.
Features of rotary mowers
In general, there are several types of mowers for mini tractors or walk-behind tractors that you can build yourself. Since this is the way to achieve the greatest savings Money, and at the same time get a quality tool.
Mowers that are made at home are:
- rotary;
- trailed;
- segment.
The basis for the rotary mower is a welded metal structure in the form of a frame. For its manufacture, it is necessary to have metal corners co standard size 40x40 mm. Body sections are installed on the structure to fix the wheels. After that, you should independently choose the type of working part, which depends on the place of work of this tool.
Rotary mower photo:
The scope of use of a homemade rotary mower extends to mowing grass or lawn areas. But, keep in mind that with the help of such a mower it is recommended to mow only high grass, as it will chop low grass. To make such a mower yourself, you must have:
- chainsaw chains;
- two discs taken from a seed drill for grain.
For the manufacture of knives, use only hardened steel. Each disc should have four knives.
On each of the disks you need to drill holes for the knives, their diameter should not exceed six millimeters. Fixation of knives occurs with the help of a tavern. In this case, it is necessary to leave a small gap between the knife and the mount, its thickness should be two millimeters greater than the thickness of the blade. In addition, you should take care of installing a protective case.
Do-it-yourself rotary mower
The design of a home-made rotary mower for a mini tractor includes knives that provide grass mowing. The knives are fixed on a special disk device. A power shaft is used to provide movement. The sliding of the mower on the surface of the earth is carried out using the lower discs.
For the manufacture of a welded frame, use the corners, it is possible to use old scrap metal. To save time on making knives, use an old tractor rotor. But, in this case To improve traction and make the mower more productive, the tractor rotor should be shortened by a few centimeters from 2 to 4, depending on the power of the minitractor. This mower model has a beam height of not more than 350 mm.
For self-construction of the rotor, you should take a metal sheet and cut out two circles in the form of disks from it, each with a diameter of 390 mm. To save on the purchase of a metal sheet, it is possible to use the bottom from old barrel. In the center, legs are welded to the discs to ensure their rotation. Due to the influence of centrifugal force, the process of mowing the grass will be carried out.
Carefully monitor the strength of the fastening, in the process of welding the legs, as the connections must be as reliable as possible.
A disk taken from a peeling device is suitable as a lower support; its diameter should not exceed forty-five centimeters. The old one is suitable as an axial shaft metal pipe, with a cross section of not more than three centimeters. To make the structure, bearings No. 180 106 are also required. A hole should be provided on the pipe section for installing the lower bearing, a second bearing is installed on the surface of the pulleys. This requires a welded pulley.
On a pre-prepared shaft, put on a disk on which there are already knives. Then, using a welding machine, weld the pulley to the pipe. The rotation of the structure will be carried out by two bearings.
Such a model of a rotary mower is characterized by the presence of a grip of 1.10-1.15 cm, while the number of revolutions of the shaft reaches 1500 pcs. The mower should be installed and then welded onto a welded frame made of metal corners. To ensure the safety of work, care must be taken to install the casing. At the junction of the tractor and the mower, directly at the junction of the belt with the figure eight, it is recommended to install an additional bearing, which will make this connection more durable and ensure softness in the operation of the mower, in addition, the friction of the belt will be reduced.
To simplify this model of rotary mower, weld the lower disc directly to metal structure from the corner.
Tip: If you do not have the skills to work with welding machine, it is better to entrust this procedure to an experienced welder in order to avoid damage to the device and make it more durable in operation.
This model of rotary mower allows you to mow at a speed of 8-12 km per hour. With a quick mowing process, the grass will turn out to be chopped, with a slower one - whole. Such a mower is capable of cutting vegetation by 6-8 cm. It is used for mowing grass or cleaning household plots from weeds.
Homemade rotary mower from improvised materials
Materials for manufacturing:
- four wheels of the same size, with a diameter of up to 45 cm;
- two axles for mounting wheels;
- a metal sheet;
- bottom from an old metal barrel;
- four knives;
- nuts and screws for fixing knives;
- welding machine;
- chainsaw;
- a handle for control or a pipe for its manufacture.
Instead of wheels, you can use an old baby stroller with metal wheels. A chainsaw is fixed on it, which will rotate the so-called rotor.
A temporary gear from the pulleys will help to replace the tire. A metal sheet is installed on the bottom of the stroller, which must be cut with a grinder, in accordance with the dimensions of the stroller. In addition, it is necessary to cut the bottom in the form of a disk from metal barrel. From another barrel or improvised means, cut a casing that will have a diameter slightly larger than the disk. It is possible to manufacture an aluminum visor, which will help to lay the cut grass. A handle is used to control the mower, if there is one from a stroller, use it, otherwise, build a handle yourself. Attach knives to the disk, watch the strength of the joints. Further, all parts are assembled by welding. First, a metal sheet is attached to the stroller, then a casing is fixed on its surface and a disk is inserted into it. During the start of the chainsaw, this mechanic rotates and mows the grass.
The cost of purchased rotary mowers
The cost of a rotary mower, first of all, depends on the width of its capture. In addition, the price is affected by:
- number of rotors;
- the quality of the material used in the process of its manufacture;
- company manufacturer;
- appointment;
- availability of additional functions;
- mower type;
- rotational speed;
- the height of the grass she mows;
- weight, etc.
The average cost of a rotary mower for a walk-behind tractor is from $ 100. At the same time, it is equipped with two rotors, has a capacity of 3500 rpm. The working width of this mower is 80 cm.
The cost of a rotary mower for a minitractor is from $300. However, it has a slightly large grip and dimensions. Also, these mowers are characterized by higher productivity and are suitable for processing medium-sized plots.
A rotary mower for a tractor is much more expensive, its average price is $ 1,500. At the same time, the capture width is doubled and even tripled. This equipment is designed to work on large areas of land.
