Motoblocks "Neva" are today one of the most popular and widely used types of agricultural equipment for home and farming. A rotary mower for a walk-behind tractor is often used as an attachment installed on this unit. This type of device consists of a support mechanism and several rotating disks equipped with special blades. This design is highly reliable and easy to use, and is also most preferred for intensive and safe work.
What types of mowers are there for walk-behind tractors?
Mounted mowers for walk-behind tractors are usually divided according to the principle of operation into:
- rotary. in them, active knives perform rotational movements relative to the vertical axis. Moving forward, the machine-tractor unit mows vegetation: grass and small shrubs;
- segmental, have a special frame on which two rows of cutting elements are located. They perform reciprocating movements, cutting the stems. During translational movement, the active working body performs cutting in the root part.
Each type has its own characteristics. Users note positive and negative indicators for each design.
Required tools and materials
Considering that the manufacturing schemes for mowers, which will be given in our article below, were invented taking into account the use of available materials, any of the named components can be replaced. If you do not have the opportunity to obtain any of the specified materials, but have an idea of how to replace it, you can freely make changes to our offer.
We offer only an indicative list of what may be useful:
- welding;
- fasteners;
- metal corners;
- the bottom of an unnecessary iron barrel or any other piece of metal of a similar shape;
- several cutting plates;
- axle for wheels;
- wheels.
Purpose of mowers and requirements for them
Mowers are designed to cut grass at a certain height from ground level. When creating a product, designers receive specific technical specifications. It takes into account certain requirements, which are subsequently implemented by ready-made attachments:
- Working width. This parameter cannot be too significant, since walk-behind tractors are intended for use in small areas. They have to move in a straight line and also avoid obstacles.
- Cutting height. It is an important indicator of work efficiency. The lower the vegetation is cut, the more biomaterial is obtained for drying and feeding to animals.
- Permissible height of grass or shrubs. Depends on the thickness of the stem in the cutting area, as well as the convenience of work - falling tall plants will make movement difficult. You will have to go back often to overcome difficult sections.
- The speed of movement of the unit, which will determine the performance of mowing vegetation.
- Weight of attachments. The heavier the device, the more difficult it is to transport it and mount it to the walk-behind tractor.
- Ease of use. Includes access to control handles (on and off) and mode adjustment (faster or slower).
- Maintainability. This is an opportunity to restore equipment on your own or you will have to constantly contact service centers.
- Use of wear-resistant and durable materials. This is a guarantee of long-term operation in difficult conditions of cutting dry and wet grass.
- Safety fences. To prevent human or pet body parts from entering the cutting area.
Instructions for installing the completed mechanism on a walk-behind tractor
It is not enough to simply build a device. It is important to attach it correctly and connect it to the walk-behind tractor. Perform these steps in the following order:
- The walk-behind tractor is switched to reverse mode, the mower is packed in a casing for safety. The pin, designed to lock the connection unit, must be equipped with a spring.
- The tensioning device (belt) is secured from the completed structure.
- The pulley located on the mower is put on the upper clutch. It is important to ensure that the front of the hub is directed towards the tensioner flange.
- All existing parts are held together with a screw.
- Secure the mower by putting on the tension belt. Fix it with pins.
- Attach an apron to the walk-behind tractor. It will prevent the grass from getting on the owner.
It is important to accurately adjust the tensioner. This is done by turning the handle in the direction of movement of the walk-behind tractor.
Additional recommendations
There are generally accepted safety recommendations, which even specialists are not advised to ignore:
- When working with a haymower (homemade or factory-made), you need to take regular breaks to technically inspect the mechanism. Fasteners and tension belts require special attention.
- If there is a need to replace a part or the entire structure, the entire mechanism should be de-energized.
- When working, wear special clothing and safety glasses.
- If the front or side mower is running, only walk around it from behind.
- You should not increase the speed, this will affect the quality.
- The cutting elements are not touched even when turned off, only when the mechanism is de-energized.
The last step will be to test the mower in a small area and at the lowest speeds, engaging the clutch. Before work, remove all loads, this increases engine performance and prevents it from overheating.
When assembling a structure yourself, the main thing is to comply with safety measures. All parts are securely fastened, since the mower is a high-risk device. Therefore, if the skills to operate the mechanisms are not enough, it is safer to purchase ready-made attachments.
Segment mowers for walk-behind tractors
The design, developed in the middle of the 19th century, has not undergone significant changes. A number of fixed segments are fixed to the frame. Above is a movable rod (it performs a reciprocating movement relative to a fixed frame), and a second row of segments is installed on it. The stem caught between the segments is cut.
Such mowers are used when the grass is tall. They are effective in overgrown areas. Traditionally, segment mowers are used to cut grass into hay.
Many users note that it is convenient to use a segment mower both on the plain and in areas with difficult terrain. The cut is made close to the ground, which increases the mass of harvested material. When mowing, the device places the cut vegetation into a windrow. this improves the conditions for drying and obtaining high-quality hay.
The speed of the unit can reach up to 4.0...4.3 km/h, which corresponds to the normal gait of a person.
The devices are produced in two versions:
- finger-type, they use additional protection of the segments (finger pads) from the ingress of solid objects into the cutting zone;
- fingerless ones do not have additional protection. The mowing is expected to be used for many years. There are no objects on them that can destroy the segments of the cutting organ.
Attention! Practice has shown that the presence of a protective finger above the segments increases maintenance-free operation several times. A complex design pays off with lower costs for restoring functionality.
Main types of mowers
All mower models are divided into two main blocks. They can be either rotary or segmental. This can also be seen by studying photos of homemade mowers.
A mower that is considered a segment mower is quite capricious to maintain due to the fact that it is prone to frequent blockages.
Therefore, work has to be stopped and the equipment cleaned. This is why homemade segment mowers are made less frequently by gardeners than rotary mowers.
How to choose a mower for a walk-behind tractor
Grass. universal food for a whole group of livestock. Vegetation mowed in the summer and properly dried turns into hay, the nutritional value of which is quite high. The dried product allows animals to exist from autumn to spring, producing food: milk and meat.
Traditionally, hay harvesting was done by mowing the grass using a simple tool, a must in every rural home. Today it is difficult to find a craftsman who can perform this operation using a Lithuanian hand scythe. The skill has been lost for various reasons; we have to look for technical devices to do this work.
Walk-behind tractors and mini-tractors are convenient power plants on which you can attach a variety of agricultural implements and machines. They are equipped with additional devices for cutting grass and making hay.
Basics for Building a Mower
There is no need to rush to throw away equipment that is no longer intended to be planned at home, since it can be used for another area of work.
Thus, mowers are created from old vacuum cleaners, supplemented with special knives, as well as even from bulky and clumsy washing machines.
The main thing is to understand the essence of the action of this technique for mowing grass, and there are many ideas from which it can be made. If you improve the grinder, then it can also be turned into a device for mowing grass.
Rotary mounted mowers for walk-behind tractors
On relatively small uneven areas, rotary mowers are used. Structurally, they represent a disk located at the cutting height. Rotation from the power take-off shaft (PTO) of the walk-behind tractor is transmitted to the executive body.
Several knives are installed on the disk, which, under the influence of the centrifugal force arising during rotation, diverge in different directions. When they come into contact with stems and blades of grass, they cut them.
Short grasses manage to end up in the cutting zone several times, so they are crushed. A grass mass is formed. Gardeners use it to mulch the soil in their gardens. Poultry happily pecks at this herbal mixture.
Rotary attachments are produced in two versions:
- Single disk. One large cutting disc is installed on the frame. It determines the working width.
- Double disc. two disks are mounted, rotating in different directions. They are installed parallel to each other. The width of the grip depends on the size of the diameters of both.
Attention! The double-disc machine is not much more complicated than the single-disc version, but during operation, the mowed grass is placed in a windrow that is formed between the discs. In the future, it will be easier to rake and transport the mown mass.

Advantages of rotary mowers
- A simple and compact attachment, it is easy to move and mount on a walk-behind tractor.
- The machine-tractor unit is transported disassembled in the trunk of a car; it is assembled at the intended site and work begins.
- Easy to maintain. Once the job is complete, it is easy to remove any remaining beveled material. When performing routine maintenance, the rubbing units are lubricated.
- The presence of guards contributes to the safe operation of the equipment.
- When mowing, the operator maneuvers easily. The center of gravity is located on the wheels, so sharp turns and changes in direction of movement do not cause difficulties.
- Rotary mowers have a relatively low price. They are purchased more often to equip energy-intensive units with them.
Measures for the safe use of segment mowers
- Before you start mowing, you need to check the connection between the attachment and the walk-behind tractor. Make sure the threaded connection is tight.
- Check the ease of movement of the movable rack with knives. Check the integrity of the segments.
- All work must be performed only with the walk-behind tractor engine stopped. The power take-off shaft may become connected due to vibration, which could result in injury to operating personnel.
- Periodically (at least once every two hours) stop the unit and check the belt tension. Carry out an inspection to look for loose or loose threaded connections.
- Move across the field, measuring the speed and power of the grass stand.
- Before mowing, check the field for stones and objects that could damage the working part of the mower.
Specifications
The following briefly summarizes the main technical indicators of the KR 05 rotary mower for Neva walk-behind tractors:
- weight – 30 kg;
- dimensions – 70 (height) × 70 (width) × 70 cm (length);
- operating speed (average) – 2-4 km/h;
- productivity – 0.1-0.15 ha/h;
- knife installation height – 4 cm;
- the dangerous zone of rotor rotation is about 60 cm.
When operating a mower with a Neva walk-behind tractor, special attention should be paid to the blades; the performance and service life of the equipment depend on them. In this model, the cutting rotor is made of high-quality carbon steel, hardened and sharpened in a factory way. The result is an inexpensive and practical tool that allows you to cut not only grass, but also small shrubs. Of course, over time the knives will become dull, but they lend themselves well to sharpening at home. To do this, you need to disassemble the mower by removing its lower part, unscrew the rotor and replace it with a new one (or sharpen it and then put it in place).
Types of devices for different situations
Here are the main situations:
- mowing haylage and silage;
- clearing the area of weeds;
- lawn mowing;
- use for cleaning the area from tops of potatoes and other crops.
Hay and silage cutting
A segment mower is best suited for this type of work, because it not only has the greatest productivity, but also uses less engine power than any other type of cutting tool.
If making such a tool is too difficult, make a rotary or reciprocating mower, they are about the same in performance and power consumption. Use an attachment with a chain cutting tool only as a last resort, because in addition to very low productivity, it negatively affects the grass, slowing down its growth, which will reduce the number of mowings per season.
Clearing the area of weeds
Weedy areas are often cluttered with branches or stones, and the ground surface is covered with potholes and hills, making it difficult to use any cutting device other than a chain cutter.
Since there is no goal to reduce the traumatic impact on the grass, the main disadvantage of devices of this type is automatically eliminated. And the low productivity is compensated by the minimal maintenance of such a mower, because the chain does not require straightening or sharpening.
Lawn mowing
If you need to use a tractor to mow a lawn or any other green area with a flat ground surface, then reciprocating and segment cutting tools will do the job best.
However, a reciprocating mower is much simpler to manufacture and maintain; in addition, it not only cuts, but also lifts the trampled grass.
The only conditions on which the cutting efficiency of a reciprocating mower depends are:
- a sharpened knife with an aerodynamic wing (you can read more about such knives here);
- a lid covering the knife, which increases the efficiency of creating air flow;
- high rotation speed (2700 and above rpm).
Therefore, you will have to install an overdrive gearbox, because the tractor PTO rotation speed is 540 or 1000 rpm. But even with such a gearbox, the design of a reciprocating mower is much simpler than its segmented counterpart.
Clearing the area of potato tops or other crops
If you need a mower only for this application, then choose a chain cutting tool, because it requires minimal manufacturing costs.
When both conditions are met, the untwisted chains not only cut, but also crush the tops, turning them into good mulch.
If, in addition to clearing the area of tops, she will have to do other work, then the best choice would be a rotary mower, because it combines:
- ease of manufacture;
- efficiency;
- ability to work in cluttered areas.
Making a mower for a walk-behind tractor with your own hands
Restless DIYers can assemble anything: a moonshine still, a terminator, a hadron collider, and even a mower for the Neva walk-behind tractor or any other cultivator. You will need discs from an old seeder (2 pieces), an old chainsaw and material for making knives. The chain and gear unit from the saw will come in handy, but you will have to tinker with the steel for the cutting part: each disc has 4 knives, they must be sharp enough, hold an edge well and not break when colliding with the first stone. That is, any kind of steel will not work; you need alloyed low-carbon steel.
The knives are not mounted rigidly, but with the help of special pads: this way they can be removed, sharpened, and in general this design is more convenient. When rotating, the blades should not be fixed, but move freely: due to the centrifugal force, they will go beyond the disk. Examples of such solutions can be found on the Internet. It is very important to achieve minimal beating when the rotor is operating, so as not to overload the engine and not break the device.
Specifications
According to the principle of operation, this mower for the Neva walk-behind tractor is not mounted, but trailed. Its main parameters are similar to the standard model:
- average travel speed – 2-4 km/h;
- rotation speed of cutting knives (maximum) – 2400 rpm;
- grass height, maximum – 1 m.
Operating the mower requires compliance with certain rules. Before starting work, check all connections: tighten any loose ones. Standing in the mowing area directly in front of the mower is strictly prohibited - this may be unsafe and lead to injury. If any extraneous noise or knocking appears, stop working immediately.
Any adjustment and repair activities are carried out with the equipment turned off. Every 2 hours, the tension of the belt in the mower drive is checked; if it is loose, it is tightened (replaced). It is not recommended to exceed the established speed limit of 4 km/h. Stones and branches flying with great force from under the knife can be dangerous.
Important! Every 12 hours you should clean and lubricate the rubbing components and bearings with the lubricant specified in the operating instructions, then it will last a long time.
Which models are suitable?
The variety of models of additional equipment for motorized equipment creates the conditions for selecting a suitable solution for each type of walk-behind tractor. But how not to make a mistake when buying? The most popular on the domestic market are Zarya mowers. They are produced by a Kaluga enterprise; there are several modifications. To find out whether the Zarya mower is suitable for the Salyut-5 and Salyut-100 walk-behind tractors, you need to study the product data sheet. The required model will be designated KR. 05.000-04 or ZiD KR-1 (produced by the plant in Kovrov).
In addition, you should pay attention to the KM-0.5 “terminator” model with an adjustable cutting height from 5 to 100 mm and a chopper. The cutting width during operation of the product reaches half a meter
The knives do not require sharpening and have a self-sharpening structure. KNS-0.8 “Strizh” belongs to the category of segmental models, suitable for mowing roadsides, maintaining areas, and forming lawns. Its features include the lateral location of the cutting element relative to the walk-behind tractor itself. The blade of the knives has protection in the form of fingers that prevent damage.

Types of mowers
All mowers existing in nature, regardless of whether they work as independent equipment or are connected to the main power unit - a walk-behind tractor, are divided into 2 types:
- segmental;
- rotary.
Each of them has certain advantages and disadvantages, and characteristic design features: they can be connected to the Neva walk-behind tractor and can be effectively used for cutting grass over a large area. Manually, without such equipment, it would have taken much longer to deal with the shoots. A segmented mower differs from a rotary mower in its operating principle: its blades work horizontally, like scissors, receiving energy through a drive belt from the Neva walk-behind tractor. In a rotary installation, the working element is a special cutting unit (rotor); this is a more advanced option.
Important! The choice of mower by type is influenced not only by its design or the ability to connect to the walk-behind tractor available on the farm, but also by other indicators: safety, ability to work on rough terrain, price.
Segmental is the simplest equipment for installation on Neva walk-behind tractors and similar ones. The segment mower is unpretentious to use and cuts the grass quickly, widely and evenly. It is easy to handle over large areas. The main disadvantage of this solution is that the device does not tolerate uneven mowing with numerous bumps and depressions (and such things happen in life); it is more suitable for planned lawns or almost perfectly horizontal areas. In such conditions, it will show all its advantages and will help you get rid of excess thickets or trim the lawn in a short period of time.

Rotary is considered by professionals to be a more advanced solution: its cutting knives are covered with protective covers, which means they are safe for humans. The advantages of the mower include its ease of use - installing the mower to the Neva walk-behind tractor is almost as simple as installing a cultivator; there are usually no special difficulties with this. Works great on ups and downs and is not afraid of rough terrain. After mowing the grass, if such equipment is installed, clear rows are immediately formed: there is no need to additionally form windrows and stacks.
Reviews
Comments left by mower users are replete with the following excerpts:
- There is a scythe available for the Neva “KN 1” walk-behind tractor. The unit is fast and powerful, there are no problems with spare parts, overall I am happy with the machine. Before this, there was a Chinese analogue, which had to be constantly adjusted and repaired. Eventually its working parts became loose and its main mechanical parts collapsed. And “KN 1” still never ceases to please. Its feature is the ability to work effectively on uneven and bumpy terrain. While moving, the mower follows the uneven terrain and makes the grass cut quite clean.
- I am the owner of a mounted rotary mower for the KR 05 walk-behind tractor. The unit is well suited for mowing dense vegetation and dead wood. I use it mainly for clearing the fields of corn and sunflower residues. If you go over the same area twice, the bevel turns out to be almost perfect. It is quite simple to assemble a mower with a walk-behind tractor; for this you need to connect the drive with the working elements and secure the device in the front part of the structure. Using the mower is comfortable and easy. In order for the unit to serve for many years, it is necessary to carry out proper care and systematic maintenance.
Rotary mower Zarya
A common solution of the alternative Zarya brand, which can be successfully used with other walk-behind tractors. Structurally, it differs in the presence of 2 independent rotating knives mounted on the frame. Thus, the manufacturer managed to create a solution that is in some ways more convenient than the original lawn mower for the Neva walk-behind tractor. Unfortunately, due to the wide frame and 2 knives, the unit has become sensitive to working on rough terrain.
This mower has its pros and cons
Self-propelled mower
A separate group of units can also include self-propelled innovative mowers, which include products from the types discussed above.
They are characterized by high productivity, multifunctionality and the need for minimal operator effort. Rotary models often run on gasoline; they are complemented by reliable wheels with a high level of cross-country ability. Moreover, all parts for such devices are made of the strongest materials, and purchasing spare parts if necessary is not difficult.
Installation
The Zarya mower is installed on the Neva walk-behind tractor using a special kit (MB1, MB compact). If you don’t have it, you will have to purchase the necessary equipment. Installation is carried out according to the instructions and consists of several simple operations. If everything is done correctly, the unit will immediately be ready for work, that is, mow down excess green growth and leave behind even, neat rows of grass.
Segmental
This blade mower operates on slightly different principles. On the frame, which is its basis and mounted on wheels, there are cutting knives. The blades move back and forth to remove grass and plants that fall between their edges. Height adjustment is made using a slide.
The performance of such mowers is slightly higher, the degree of uniformity of mowing is almost the same, however, more care is required during operation so as not to hit an obstacle. Mown grass is laid in rows that are easy to collect; this function is included in a yard of models produced for specific types of basic walk-behind tractors.
Varieties and device
Depending on the design features of the mower, there are two types: rotary and segment.
Rotary mower for walk-behind tractor
Rotary
For these mechanisms, disk devices act as working elements. They are quite productive and absolutely safe during operation. The rotary mower for the Neva walk-behind tractor is capable of laying cut plants in even rows, which makes their subsequent drying much easier and eliminates the need to use forks and rakes. A unit of this type is used for mowing vegetation on roadsides and slopes, as well as for removing grass in private courtyards and estates. Rotary mowers can be single-disc or double-disc. They are attached to the walk-behind tractor at the front of the device. How are their activities carried out? Torque from a running engine is transmitted to the power take-off shaft, which in turn interacts with the working parts through a V-belt. Further, under the influence of centrifugal force, the disc legs come into contact with the surface of the grass and cut it. To protect the discs from stones and hard objects, the design of the unit provides protective covers.
Segment mower for walk-behind tractor
Segmental
Segment-type mowers are devices that include a frame and cutting components (pins) connected to each other by special fasteners. The principle of operation of such a unit is similar to the operation of classic scissors: one part of the mechanism is stationary, and the other makes linear movements - left and right. When the torque from the walk-behind tractor is transmitted to the mower, translational vibrations of the scissors occur and the plants that fall between their fingers are quickly and accurately cut. Thanks to the rational form of the device, vegetation is placed on both sides of the unit. The result is uniform windrows that will require additional tools such as forks and rakes to remove. The segment mower for the Neva walk-behind tractor is capable of operating in areas with complex terrain when mowing grain and grass crops. The displacement of the working component of the mower in relation to the walk-behind tractor can be about 20%.

Rotary mowers and their prices
We recommend buying a rotary mower for farmers who need to mow dead wood with a diameter of less than 100 mm, dense vegetation or hard remains of sunflower or corn. But the rotary model can also handle cleaning a lawn or a small area in the garden. It is mounted to the drive of the Neva walk-behind tractor from the front or by a trailed method. Trailed ones mulch grass, so they are not suitable for farmers who need to harvest grass for hay.
The operation of the rotary mower is carried out from the belt shaft of the walk-behind tractor. Suitable for petrol and diesel Neva walk-behind tractors, as in the video. For attachment to the latter, a special adapter is included in the package. Among the various rotary mowers for the Neva, the Kaluga Zarya and the St. Petersburg KR-05 stand out. Depending on the modification, rotary mowers have 1-2 working discs, KR - 05 has working body 1, Zarya has 2 discs. There are 4 knives attached to the disk using a movable hinge joint. When the disc moves, the movable cotter pin allows the knives to turn under the influence of centrifugal force and they cut the grass. At Zarya, the discs rotate towards each other, the lawn cultivation width is greater. The design of the rotary model is located on a special slide; they allow you to adjust the height of the grass cut with a simple movement. The mown vegetation is distributed in even shafts on both sides and is easy to collect with a pitchfork.
Let's take a closer look at the popular segment models for the Neva walk-behind tractor in video and photos. In the video below you can see how the equipment works in the field and along the road.
Rotary "Zarya"
The official manufacturer of the Zarya rotary mower, Kadvi, is located in Kaluga. But there are many home-made and Chinese models on the market, made according to the designs of the manufacturer “Kaluga Engine”. Externally, they differ only in color - the Kaluga Zarya is bright red, as in the video. But this is not the main difference. The Chinese ones have worse quality, as they use low-quality material for production.
Characteristics of the Zarya mower for the Neva walk-behind tractor and the price of analogues and licensed equipment in the table:
| TX "Zarya" | Indicators |
| Performance | 0.2 ha/hour |
| Maximum speed | 2-4 km/h |
| Working width | 800 mm |
| Rotation speed of working bodies | 2000-2400 rpm |
| Maximum cutting height | 100 cm |
| Equipment weight | 35 kg |
| Price for the official model/Chinese analogues | 12,500/11,700 rub. |
You can buy cheaper directly from the manufacturer in Kaluga. The retail price is 10-15% higher and it is more profitable to buy in bulk. Spare parts from the domestic model are suitable for all Chinese analogues, therefore, in some cases, you don’t have to overpay. The price for used equipment starts from 5,000 rubles, but we do not recommend purchasing equipment older than 10 years.
Rotary and segment mowers for walk-behind tractors: comparison and detailed analysis, prices and characteristics
There are two types of mowers that can be installed on a walk-behind tractor - rotary and segment. They differ only in the operating principle. Both have their merits; it is impossible to say unequivocally which is better. It all depends on the goals and characteristics of your site.
Rear rotary mower SCOUT RM-2
Its parameters and purpose are largely similar to the previous model; it mows grass and plants, including shrubs with a trunk diameter of up to 1 cm.
Installed on the rear of motor cultivators, operation is ensured by the rear key shaft from the power take-off. Available for a number of models of heavy walk-behind tractors, such as Garden Scout GS105-135, Crosser CR-M6. Crosser CR-M9, Patriot Garden, Green Field MB-105-135, Agrostar and several others. The mount is unified and can be installed on many walk-behind tractors without any problems.
This walk-behind mower is very reliable and unpretentious; the only thing it requires is periodic maintenance after several hours of operation. It consists of lubricating joints and gears.
Height adjustment is made by shifting the center of gravity to the mower. The working tool is two disks that rotate towards each other. Each has 4 knives attached, which rotate freely; under the influence of centrifugal force, the knives extend beyond the perimeter of the disks, cutting off grass and small bushes. All necessary spare parts for connection are included with the mower.

Peculiarities
The modern rotary mower for the Neva walk-behind tractor has a simple and understandable principle of operation. It contains cutting discs that rotate during operation. Grass stems and young bushes with a diameter of up to 1 cm falling between them are easily cut off. After mowing, the vegetation forms neat rows, which can later be easily collected or left to dry for a while.
Rotary mowers are characterized by compact dimensions, so they are convenient to store and transport over any distance. Zarya mowers are equipped with two discs on the frame, which significantly speeds up and simplifies the mowing process. Such equipment is attached to Neva walk-behind tractors using a special V-belt, which forms a connection to the drive of the main unit. Unlike country models, rotary-type double-disc mowers are considered more powerful and professional; they are used mainly on farms or on large areas.
Among the features of Zarya rotary mowers, one can note their adaptation to mowing the stems of cereal crops, which are characterized by high strength and hardness. The knives have free movement and do their job quite confidently on uneven ground surfaces. Using a modern rotary mower, you can mow areas with mole holes, dense root mass, and uneven areas of soil. The package includes a locking system that is activated when the permissible load is exceeded.
Among the obvious advantages of Zarya mowers for walk-behind tractors, one can note the mechanism for discharging cut grass, which makes it possible to significantly facilitate the process of further maintenance of the site. Compared to shearing models, it is safer and allows you to work without stopping over large areas of the area.
Homemade rotary mower on a walk-behind tractor
A homemade rotary mower on a walk-behind tractor is used to cut grass for hay and to trim the lawn. If the grass is small, then the mower will simply chop it up, and tall grass will be cut down.
Let's consider a model made for the Neva walk-behind tractor and similar models. We use two disks from a grain seeder, and a chain and gearbox from a chainsaw. Four knives are needed per disc. They are made of hardened metal. To install them, holes with a diameter of six millimeters are drilled on each disk using a carbide drill. Using a shredder, we attach the knives to the disks. We also maintain a gap between the knife and the shredder, which is 1-2 mm greater than the thickness of the knife itself.
Thanks to this, the centrifugal force, when rotating, will straighten the knives from the disk, and they will mow the grass. At the same time, the ability to rotate the knives 360 degrees should be preserved, which is done to ensure greater safety of the knives when they collide with something hard. To make the axis on which the knives will be attached, durable carbon steel is used. The diameter of the axis must be at least eight millimeters. In order for the knives to move freely, you need to tighten the axle with a disk until it stops.
These two disks are mounted on a welded frame and communicate with the PTO drive. The rotation of the discs should occur towards each other, which will allow the mown grass to be stacked in rows.
Rotary mowers and their prices
We recommend buying a rotary mower for farmers who need to mow dead wood with a diameter of less than 100 mm, dense vegetation or hard remains of sunflower or corn. But the rotary model can also handle cleaning a lawn or a small area in the garden. It is mounted to the drive of the Neva walk-behind tractor from the front or by a trailed method. Trailed ones mulch grass, so they are not suitable for farmers who need to harvest grass for hay.
The operation of the rotary mower is carried out from the belt shaft of the walk-behind tractor. Suitable for petrol and diesel Neva walk-behind tractors, as in the video. For attachment to the latter, a special adapter is included in the package. Among the various rotary mowers for the Neva, the Kaluga Zarya and the St. Petersburg KR-05 stand out. Depending on the modification, rotary mowers have 1-2 working discs, KR - 05 has working body 1, Zarya has 2 discs. There are 4 knives attached to the disk using a movable hinge joint. When the disc moves, the movable cotter pin allows the knives to turn under the influence of centrifugal force and they cut the grass. At Zarya, the discs rotate towards each other, the lawn cultivation width is greater. The design of the rotary model is located on a special slide; they allow you to adjust the height of the grass cut with a simple movement. The mown vegetation is distributed in even shafts on both sides and is easy to collect with a pitchfork.
Let's take a closer look at the popular segment models for the Neva walk-behind tractor in video and photos. In the video below you can see how the equipment works in the field and along the road.
Rotary "Zarya"
The official manufacturer of the Zarya rotary mower, Kadvi, is located in Kaluga. But there are many home-made and Chinese models on the market, made according to the designs of the manufacturer “Kaluga Engine”. Externally, they differ only in color - the Kaluga Zarya is bright red, as in the video. But this is not the main difference. The Chinese ones have worse quality, as they use low-quality material for production.

Homemade segment mower on a walk-behind tractor
This segmented mower on a walk-behind tractor is made from metal beams 15x50x120. 12 holes need to be drilled in them so that their dimensions are suitable for M8 bolts. In the future, a guide rail (89 cm) with teeth and knives will be attached to these bolts. Knives are installed on both sides of the beam.
At both ends of the beam, runners and clamps are attached. A wheel is attached to the main frame, which can be removed from an unnecessary stroller. Under the influence of the walk-behind tractor PTO, the cutting part of the mower begins to work. This can be seen in more detail in the figure:
main welded frame (1), braces (2), gear wheel (3), fixation and adjustment of the braking system (4), pawl for fixing the brake (5), main arches (6 and 8), hinged body (7), leg (9), fuel line (10), regulator valve (11), gasoline container (12), handle (13), levers (14 and 17), snap mechanism (15), mounting bolt (16), gas control lever ( 18), clamp (19), engine muffler (20), engine (21), fixing fasteners (22), fairing (23), cutting knives (24 and 25), cover (26), slide (27), element fixation (28), knife frame (29), rod (30), pin (31), plates for pressing the lower and upper parts (32 and 33).
A mower assembled according to this drawing easily cuts grass. You can see this homemade mower in action in the video.
Design and principle of operation
There are several types of grass cutting equipment. The most popular and, at the same time, the most often produced on their own are frontal ones, which involve installing the mower on the walk-behind tractor at the front. Three types of structures can be distinguished:
- rotary (disc);
- segmental;
- "cart".
These types of equipment differ not only in appearance, but also in their operating principle. It is necessary to understand it, since the technical capabilities of the device must fully meet the expectations of its owner. Let's take a closer look at each type separately.
Homemade mower for walk-behind tractor (rotary, segmental)
To facilitate the physical work of a person on a personal plot, more than a hundred different canopies for the walk-behind tractor are offered. But not everyone can afford to purchase such equipment, because its cost is not cheap. The article describes a homemade mower for a walk-behind tractor, the pros and cons of popular designs.
When assembling such a mower, the most important thing is to get a safe and high-quality model. To make a mower for a walk-behind tractor with your own hands, you usually use improvised components from agricultural machinery. After all, the main goal pursued by the creators of a homemade mower is saving money and achieving maximum results. Some models that ordinary gardeners come up with often surprise professionals with their design and simplicity of design.
Using a chainsaw
A gasoline mower will be an excellent help on the farm. But first you need to prepare tools and spare parts. The domestic models “Druzhba” and “Ural” are suitable for solving the problem. Additionally you will have to purchase:
- metal corner;
- 2 wheels;
- pipe cutting;
- metal knives;
- metal plate;
- rotor discs;
- bearing;
- accessories.
As for the corner, it will be used to make a rigid frame. But a metal plate will be needed for the platform. You don’t have to buy wheels, but borrow them from a stroller or cart. The pipe cut should have a diameter within 5 cm. To mate with the pipe, you will need a gear. A homemade haymower will be made using accessories, namely:
How to connect a homemade mower to a walk-behind tractor
A hand-assembled mower will not produce the desired result if it is incorrectly attached to the walk-behind tractor. There are certain rules that must be followed when installing a mower.
First of all, you need to put the walk-behind tractor into reverse mode. Before connecting to the PTO, a connecting unit is placed in the coupling socket. Using a pin with a spring you need to lock the connection. The absence of a spring will lead to a malfunction of the towing mechanism.
For greater safety, you need to cover the mower blades with a protective cover. The wheels of the walk-behind tractor contain weights that help in cultivating the soil. Since they are not needed when cutting grass, they should be removed. When mowing grass with a mower, you should start at the lowest speed. There is no need to rush when turning and make them smoothly. If you assembled a mower for a walk-behind tractor with your own hands, first of all, its operation should be safe.
When a homemade mower is connected to a walk-behind tractor and it works, quite high revolutions of the discs with blades are achieved. If the fastener breaks, you or people around you may be injured. Therefore, first think about whether you have the skills to make such a device. After all, it will be much cheaper to purchase a ready-made mower for a walk-behind tractor than to buy medicine and treat damaged organs or nerves.

Description of mowers
The main function of this type of agricultural machinery is already contained in their name. They are designed to cut grass.
The rotary mower has long received another name, which can be heard no less often than the main one. It is also called disk. Since special discs are responsible for the main function of cutting grass.
As a rule, a disc mower is a homemade mower for a mini tractor and it only works in conjunction with it. Its essence is quite simple, namely, the wheel is driven, which is considered the support of the entire structure. Then, thanks to the wheels, the cutting system begins to function.
