Helpful information
A mower for a walk-behind tractor or MTZ, LTZ tractors is a modern and effective way of caring for your site, mowing grain crops or wild plants. Technological models are used in the warm season and allow you to quickly put in order the backyard or summer cottage area. Mowing vegetation, making hay and keeping order takes a short time. It is much more convenient to use attachments for a tractor or its mini-version than outdated tools.
Modern mowers are presented in several types, each of which has its own advantages. The choice between a rotary and a segmented unit depends on the characteristics of the site and the goals set. Both devices in high-quality performance are productive, efficient and durable, and also affect the reliability of all equipment.
Principle of operation and scope
Rotary mowers shred plants, mow and place them in even shafts or evenly across the field, which greatly facilitates the transport of hay. Many models have a safety device that deflects the knives when they hit an obstacle. Also, in some versions of mowers, the knives can be deflected up to 45 °, which will provide a better clean cut.
Modifications of this device differ in the number of cutting parts, the method of attachment and the processing area. Many models can be used for harvesting forage, as they are equipped with a weed grinder. The work of the device takes place with the help of the selection shaft of the tractor using a bevel, cardan or other transmission.
BCS sickle bar basic setup notes
Rotary mowers are ideal for:
- clearing the field from weeds;
- pasture mowing;
- removing grass.
The unit has sufficient maneuverability and ease of use. Its width must be selected taking into account the amount of work and the size of the area to be treated.
BCS Handlebar “wear” adjustments
The saw blade for the segmental finger mower consists of two metal parts: movable and fixed. According to the principle of operation, the mechanism of the device resembles a scissor. Cutting parts are shaped like sharp-edged triangles called segments or fingers. The grass is cut between the edges of the knives, stacked in rows and is easy to collect. The double-blade fingerless mower is characterized by two moving parts that move in opposite directions. Such a device cuts cleaner, does not get clogged with debris.
- mowing thick stalks of dry grass;
- weed removal;
- mowing of naturally growing grass and seeded crops.
For reference. During operation, protective measures must be observed. The segment mower easily handles plants with a thickness of 10 mm and a wire of 3 mm.
Advantages and disadvantages of a rotary mower
The model range is wide enough and you can choose suitable devices for different types of driving machines. All rotary mowers combine the following advantages:
- even mowing and neat folding of the grass;
- protection from stones at the disc with knives (the main difference from other types);
- easy maintenance and excellent maintainability.
Cutting parts adapt to the relief.
- lower performance compared to segment;
- poor quality of work at low speed.
Not very suitable for mowing soft grass.
Rotary or disc implements must be selected for specific conditions. Powerful cultivators are suitable for removing thick and tough stems. The large mass and width of the mower cope with vegetation in a large area with difficult terrain.
Service features
One of the main advantages of rotary models is that they practically do not require technical knowledge for operation and maintenance. Such equipment is chosen by farmers due to its simplicity of design and the absence of the need for frequent repairs. The condition of the device will need to be monitored, because spare parts for trailed mowers wear out over time and require replacement or maintenance. Repair is simple, one person can handle the actions.
For efficient operation, lubrication, parts are checked for malfunction or damage, knots and chain adjustments are made.
The need for frequent maintenance of the segment mower depends on the model. Attachments for large equipment may need this every shift and at the end of the working season. The mower for any tractor is cleaned of dirt, grass and other things, the reliability of the attachment of the cutting plate knives is checked. Periodically, the elements will need to be sharpened or replaced, and lubrication is also required. The segment mower is more difficult to maintain, since it has a more complex structure and time-consuming hanging process.
Design differences
A rotary mower is a base frame on which several cutting discs are installed. On the sides there are sleds for sliding the device on the ground. Cutting the grass is carried out by discs with knives that rotate while driving. They rotate in different directions so that vegetation is cut evenly. In the mower, you can change the angle of inclination.
For reference. Rotary cultivators are convenient for processing swampy, clogged and uneven areas.
On MTZ, devices are attached to the front, side or behind to the frame. The unit also consists of a subframe, counterweight, drive, hydraulic system. The cutting system is based on the use of several rotors, depending on which equipment the mower is installed on. The hinged structure, which is located at the back, does not have its own chassis, but it can have one or more wheels. The hitch, located in front of the walk-behind tractor or tractor, has its own frame, to which cutting parts and controls are attached.
A segment mower, like a rotary mower, is suitable for a mini-tractor and its more powerful version. The design resembles a lot of scissors that cut the grass. A walk-behind tractor with equipment performs well the tasks of mowing vegetation along the roadside and in tight places on the site.
For reference. The segment mower is equipped with a protective cover and can be used in all weather conditions and climatic zones. The use of attachments or trailed implements speeds up the preparation of hay several times.
The main units of the segment cultivator include a frame base on a wheel base, a cutterbar consisting of many knives, a drive and a bar. Height adjustment is carried out using the side slide. The executive body of the equipment is of two types: segment-finger and double-knife fingerless.
Advantages and disadvantages of a segment mower
One of the main advantages is the ability to work in any conditions. Segment equipment copes well with wet and dry grass, restrictions can only be on the side of the tractor’s cross-country ability. Benefits:
- fast and high-quality cut of grass without crushing it;
- high performance;
- cutting grass of any type;
- lack of hydraulics;
- the ability to cling to self-propelled and hand-held agricultural machinery.
Among the disadvantages of which the device is few, it should be noted:
- exactingness to the cleanliness of the site (absence of solid objects);
- more time consuming service process;
- greater weight and dimensions in comparison with the rotary one for the same tractor model.
Any type of cultivator is a significant relief of labor in agricultural work. To choose one or another device, you need to familiarize yourself with the description of the models, which contain a list of used types of special equipment and power. Factors that will affect the acquisition: type of mown vegetation, area and relief of the site, the purpose of mowing and the cost of equipment.
What kind of mower do you need?
Next are the tasks. High-performance rotary mowers do not always provide surface quality; it makes no sense to buy something very powerful for an infield with a lawn, it is better to choose a model with a mulching function. And, conversely, in a subsidiary farm where there is cattle, it makes no sense to think about a flat surface after processing, it is better if the cut grass will fit into rows for harvesting. It makes no sense to argue about the merits of rotary and segment mowers, although many prefer the first type. It’s easier and safer.
The question of price is always relevant, on average it is about 15 thousand rubles, give or take. The money is not very big, but it is not superfluous, so you need to think about further repairs and maintenance after some time. Here, models of domestic production are out of competition, for obvious reasons.

On the side of the frame there is a slide, by means of which the cutting height of the grass is regulated. The operation of a rotary mower is provided by a walk-behind tractor using a transmission while driving.
The number of knives determines the performance, the more there are, the higher the speed, but when choosing, you need to start from the characteristics of your motor-cultivator, namely its power.
According to the methods of aggregation with a walk-behind tractor, mowers are divided into groups:
- trailed, or frontal, it is located in front of the walk-behind tractor;
- hinged, or rear, it is attached from the back;
- semi-trailed, it is installed on the side.
The main advantage of a rotary mower for a walk-behind tractor is its ease of operation, almost anyone can operate it, while ensuring complete safety.
Such mowers are made mainly in Russia and China, they are almost identical, although the reliability of domestic products is higher, they require less care and maintenance.
Rotary and segment mowers for motoblocks: comparison and detailed analysis, 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 principle of operation. Both have their own merits, it cannot be said unequivocally that it is better. It all depends on the goals and characteristics of your site.
How to do it yourself

Drawings are not difficult to find on the Internet, but a frame from a corner or from a metal profile will serve as the basis for a rotary mower. Or take the rotor from the tractor, reducing it based on the power of your walk-behind tractor.
Working elements are knives that are mounted on discs cut from a metal sheet. The fastening takes place as follows: an axial shaft (pipe) is welded in the center of the circles, a bearing is installed on it, another bearing is attached to a pulley.
Working units with knives are put on the axle, ease of rotation due to bearings, grass grip varies up to a meter, approximately. The finished structure is mounted on a welded chassis with wheels, and closes with a casing on top. Homemade moto scythe can be either single-disc or double-disc.
This is in a nutshell, you can see in more detail on the video, for example, this
If you need a wider grip, then there are two circles, like here
The segment mower is a little more difficult to manufacture and will require more skill and time. For its base, a small-section pipe will serve, in which sockets for mounting bolts are made. A strip of metal with teeth and knives is installed on them, the knives are equipped with clips for the drive, and clamps and sliders for movement are attached to the pipe. Work is provided by a drive from a walk-behind tractor.

Each of the types of equipment has its own characteristics and is designed to perform work of a certain complexity.
Homemade mower-cart with your own hands
With a self-propelled mower, you can easily get rid of grass with a wide stem. Consider the features of manufacturing the unit.
Process description
The first step is to drill a hole in the discs using a 6 mm carbide drill. Then you need to attach the splint to the opener, and the knives to the splint.
Please note that the distance between the shank and the knife should be a few mm more than the thickness of the knife. This moment is very important and necessary in order to straighten the knives from the disc with the help of centrifugal force, which would ensure the performance of the main function. mowing the grass. A prerequisite is 360 ° rotation of the knife. This will protect him from damage when colliding with stones or hard objects.
To make the axles of the knife fasteners, you need carbon steel, the diameter of which must be at least 8 mm. It is necessary to tighten the axle to the stop using a disc.
Difficulties with the assembly of a rotary mower will not arise if you strictly adhere to the recommendations.
