The KSF-2.1 segment mower is designed for mounting on mini-tractors and walk-behind tractors. This device is designed to mechanize hay harvesting processes, getting its name due to the special type of grass-cutting elements - in the form of large sharp triangles. Also called "segmental finger".
Advantages and disadvantages
In addition to the use of this segment mower model in any weather and in various climatic zones, this equipment has several important advantages that are highly valued by most farmers.
Advantages:
- high efficiency, which is achieved thanks to relatively high-speed work and a comfortable processing width - over 2 m;
- the small weight of the attachment makes it possible to use it on small traction units;
- the low energy consumption of the two-blade mower KSF 2.1-B allows significant savings in money and does not increase the cost of hay while reducing the volume of hay harvesting;
- easy control of equipment without using hydraulics allows you to do without unnecessary personnel, except for the tractor driver;
- relatively low cost of equipment and spare parts. Efficient operation of the unit at high speeds and long service life.
Perhaps one drawback of the KSF mower is the equipment’s demands on the cleanliness of the mowed areas, since the entry of foreign objects into the working cutting units can damage the unit.

Application area
They are used in various geographical areas in any climate, except semi-desert and desert areas.
The use of a mechanized process speeds up hay harvesting by 7–8 times.
The tractor segment mower is also successfully used for clearing firebreaks and weeds in areas between trees. You can use it to mow the lawn by attaching it to a walk-behind tractor.
The unit cuts the grass at the root, without fear of wetlands and a large number of roots.
Storage rules
7.1. Mowers should be stored indoors. Storage on sites under a canopy is allowed, subject to mandatory conservation, sealing and removal of components requiring warehousing. When placing the mower for long-term storage, responsible persons must be appointed. Mowers prepared for storage must be handed over to the machine operator and accepted by the responsible person.
During the storage period, preventive work is carried out aimed at preserving the working parts of the mower. After removing the mower from storage, preparing it for operation (after performing maintenance) is carried out by running in and debugging the working parts, after which a certificate of acceptance of the mower for operation is drawn up.
Device
The single-bar mower model KSF 2.1-B consists of the following main components:
- a metal frame on which all other elements of equipment are mounted and the attachment is attached to the power unit;
- a drawbar connecting the cutting elements to the mower frame;
- working unit with cutting elements (fingers);
- a connecting rod connecting the cutting elements to the drive mechanism;
- The drive of the unit consists of an eccentric pulley, a box, V-belts and a cardan drive.
When the unit is operating, the blade with cutting elements is driven into a forward-reciprocating motion parallel to the surface being processed. The plant stems are pressed by movable blades against the stationary elements of the blade and cut off, placing them in a windrow.
Scheme KSF 2.1-B
- – head of the cutting element; 2. – guide heads; 3. – cover of the cutting element head; 4. – inner shoe; 5. – outlet rod; 6. – outer shoe; 7. – field board; 8. – finger; 9. – finger insert; 10. – segment of the cutting element; 11. – clamping of the cutting element; 12. – back of the knife; 13. – friction plate.
Operating principle
The connected cardan drive from the mower to the engaged rear PTO of the minitractor provides intense, reciprocating movements of the cutting blade of the knives already at 540 rpm. and gives a uniform cut along the entire working plane of the mounted unit.
The cardan shaft is included in the price of the mower and is supplied complete with the main unit!
Cost of equipment
You can, of course, buy new equipment, the average cost of which in Russia is about 55,000 rubles, but purchasing used equipment is not the worst option. The price of used mowers ranges from 35,000 rubles. and higher. Used equipment is cheaper, there are no problems with purchasing spare parts, and it works no worse than new.
Purchasing a single-bar mower KSF 2.1-B is economically profitable due to its efficiency, low cost and ease of maintenance.

Rules of operation and adjustment
5.1. Recommendations for aggregation. Attaching the KS-F-2.1B mower to a tractor
5.1.1. Place the rear wheels of the tractor on a track of 1400-1500 mm. 5.1.2. Install the hydraulic lifting mechanism and hitch system on the tractor. 5.1.3. Using the tractor operating manual, limit the vertical movement of the trailing rods of the mounted system so that the holes in the spherical hinges of their rear ends cannot rise above 700 mm and fall below 400 mm from the supporting plane. 5.1.4. Reverse the tractor towards the mower and lower the hydraulic linkage so that the hinges on the rear ends of the trailing rods are positioned against the axis of the frame linkage. The axis of the hitch must be parallel to the ground. 5.1.5. Place the hydraulic mechanism distributor handle in the “floating” position. 5.1.6. Get off the tractor, connect first one and then the other longitudinal rods of the factor linkage to the mower linkage axle and secure them with tractor pins. 5.1.7. Connect the central link of the tractor attachment to the mower using a pin at the upper end of the frame. 5.1.8. Install the front driveline joint of the mower onto the PTO and secure it. Secure the chain. 5.1.9. Install the rear universal joint on the flywheel and secure it. Attach the chain to the pendant. 5 1.10. Install the drive belt guard. 5.1.11. Block the longitudinal links of the mounted system with special devices supplied with the tractor, so that the mower frame does not have a lateral displacement relative to the longitudinal axis of the tractor. 5.1.12. Adjust the length of the tractor's central link so that the support arm of the hitch axle is positioned vertically to the ground. 5.1.13. Connect the high pressure hose through the adapter fitting to the hydraulic cylinder and, through the breakaway coupling, to the hydraulic system of the tractor.
5.2. Regulation.
5.2.1. Adjust the position of the knife in the cutterbar so that when the cutterbar is assembled, the front ends of the segments rest on the guard plates of the fingers. Fingers with a gap between the end of the segment and the shear plate or having a vertical deviation compared to others, straighten them with careful blows of a hammer on the tip of the finger. A gap of up to 1 mm is allowed between the segments and the rear ends of the shear blades. The knife clamps must touch the segments; If there is a gap, bend them with light blows of a hammer. For normal operation of the cutting apparatus, it is necessary that the knife segments be sharply sharpened and located in the same plane. If any segment deviates, carefully straighten it. After straightening the pins and clamps, tighten all bolts securing the pins with nuts until full. 5.2.2. Adjust the position of the cutting device relative to the tractor so that in the cutting device the tip of the finger located next to the outer shoe extends forward (along the tractor) by 35-55 mm relative to the tip of the finger located next to the inner shoe. This is achieved by changing the length of the truss. 5.2.3. Adjust the position of the connecting rod so that in the extreme positions of the connecting rod the middle of the knife segments reaches the middle of the fingers. This is achieved by changing the length of the connecting rod by rotating the head housing. Overrunning of the knife towards the outer shoe is not allowed, since in this case, when installing the cutting device in the transport (vertical) position, the connecting rod will be pushed into position. For smoother operation of the knife and connecting rod in the working position, the center line of the connecting rod should preferably lie parallel to the center line of the knife (when viewed from above).
Adjust the relative position of the connecting rod and the knife by turning the eccentric bushing (4) (Fig. 3) in the shoe hinge (3). To do this, unscrew the bolt, turn the bushing (4) in the required direction and install the bolt in another hole in the bushing. 5.2.4. Adjust the tilt of the cutterbar. Having loosened the bolt connecting the hinge (3) (Fig. 3) to the drawbar beam (7), adjust the installation of the hinge and the cutting device connected to it at the required angle of inclination forward or backward within the elongated hole of the bracket welded to the beam. When the grass is laid down, tilt the cutting device forward so that the fingers do not press the grass, but go deeper into the laid down mass, lifting it. When working on uneven or rocky soil, tilt the cutting unit backwards to prevent the tines from digging into the ground and skipping stones underneath. 5.2.5. Adjust the cutting height by rearranging the soles of the inner and outer shoes: for an increased cutting height - to the holes located above, for a lower height - to the holes located below. 5.2.6. Adjust the field board and inner shoe guard to securely separate clipped grass from uncut grass and clear the path for the inner shoe to pass on the next run. 5.2.7. Adjust the pressure of the shoes on the soil so that when the cutting device and tractor wheels are located on a horizontal supporting surface, the pressure of the inner shoe is 200-300N (20-30 kg), the pressure of the outer shoe is 100-200N (10-20 kg). Adjust the pressure of the inner and outer shoes on the soil by changing the tension of the spring of the balancing mechanism. 5.2.8. Adjust the tension of the V-belts by moving the drive pulley using a tension screw with a spring.
5.3. Job.
5.3.1. Operate the tractor engine at full speed. 5.3.2. Adjust the operating speed depending on the terrain and micro-topography of the area. Reduce speed if areas are uneven. Use powerful tractors in higher gears with reduced engine speeds by adjusting the throttle. 5.3.3. The mower's cutting device must operate across the entire working width. To do this, drive the tractor so that the inner shoe goes as close as possible to the edge of the uncut grass. 5.3.4. If grass hangs over the cutting device, do not turn off the mower drive, move the tractor back a little, then raise and lower the cutting device using the tractor’s hydraulic mechanism to remove the hanging mass from it. 5.3.5. When moving a tractor with a mower over short distances (turns in the mowing area, minor moving from area to area), lift the cutting device using the hydraulic mechanism of the tractor. 5.3.6. To move long distances, install the cutting device in the vertical (transport) position. To do this, turn the eccentric so that the connecting rod takes the left extreme position, then lift the cutting device using the hydraulic mechanism of the tractor, manually turn it up to a vertical position, pass the end of the transport rod into the hole of the pin bar and screw the nuts onto it. 5.3.7. Use the tractor hitch to raise the mower to the required height for moving.
5.4. Transportation.
5.4.1. Mowers are sent from the factory in semi-assembled form with components and kits removed according to the “Completing List”. 5.4.2. The bag contains small parts, spare parts and technical documentation, packed in a plastic film bag. 5.4.3. The mower is transported by road and rail. 5.4.4. The method of loading, as well as the placement and fastening of packaging during transportation must ensure complete safety of assembly units and parts from mechanical damage and preservation of presentation.

Features of operation
To install the equipment on a tractor, it is fixed using longitudinal rods of the tractor hitch and the distance from the ground to their rear ends is set to about 400 mm and the lifting height is not higher than 650 mm. This is necessary to prevent lateral displacement of the frame relative to the central axis of the tractor.
When performing mowing work with a single-bar, fingerless, two-blade mower, model KSF 2.1-B, you should adhere to special rules, which will make its operation longer and safer:
- Only persons who have studied its design and operating instructions are allowed to service the equipment;
- cutting elements must be covered with a protective casing;
- before starting, you must make sure that there are no people behind and in front of the equipment;
- stopping the power unit is carried out while simultaneously turning off the power take-off shaft;
- attaching and removing equipment, as well as its adjustment and maintenance, especially knives, is carried out only when the equipment is finally stopped;
- moving equipment to a new location is carried out only with a protective casing on the working unit.
In this model of mowing equipment, one cutting element is stationary, and the second is movable. The mower is able to cut dead wood, anthills and even low hummocks. The video shows the mowing equipment in action.
Important! It is believed that KSF 2.1-B is best installed on power units such as MTZ-80, 82 and YuMZ, as well as T-25 and T-40.

Reviews
An excellent unit, but only for small and flat areas, since the guide teeth of the mower are its weak point. It is worth noting the comfortable processing width and the ability to work at high speeds. I am also pleased with the low weight of the mower and its cost. Overall, we are pleased with the performance of KSF-2 B.
The mower is quite easy to operate, and the tractor driver can easily set up the equipment on his own. Among the advantages of the equipment, the first place is that it very rarely fails, and if necessary, you can easily purchase the required spare parts. Some repairs can be carried out directly on site. After the end of the season and in preparation for the next one, you only need to replace the cutting blade.
This mower is truly a great helper when cutting grass. One of the positive characteristics of the equipment is its efficiency. If, after purchasing the equipment, you carry out routine maintenance on time, then the mower can last quite a long time and trouble-free. During operation, the equipment is practically not clogged with tangled and fallen grass, which increases its efficiency. My impressions from working with this mower are only the most positive.
Additional assembly, adjustment and running-in of the mower
Mowers are sent from the factory semi-assembled in separate units and parts, packaged according to the picking list supplied with the machine.

Modifications
Mowers of this brand are still the most popular and widespread in the Russian Federation, successfully working in the fields of collective and private farms. Such high demand is also achieved due to the variability of equipment design - the KSF-2.1 mower can be presented in different modifications:
- Fingerless.
- Equipped with the German Schumacher cutting system.
- With a hydraulic cylinder in the lifting mechanism and others.
Among them, the most popular is KSF-2.1B4, which, in comparison with the base model, is equipped with a more reliable frame and a reliable cutting tool beam. In addition, it provides easier adjustment of the inclination of the segmented blade and higher safety device capabilities.
Its “sister” KSF-2.1V requires more tractor power, but at the same time has a lighter weight and mechanized lifting via a hydraulic cylinder.

The lineup
A segment mower must be suitable for a specific tractor model, because the operating mechanism of tractors differs significantly. This applies not only to the size of the tractor, but also to its brand. There are quite a few models of mowers, among them:
- Inexpensive devices made in China - they are especially loved by summer residents and gardeners for their compact size. Soviet tractors with appropriate traction are quite suitable for them.
- Model for a tractor produced by the Russian company Bobruiskagromash. It works with a tractor equipped with a rotation transmission unit from the engine to the attachment. Its operation is activated by the shaft of this unit.
- The three-beam KP-F-6 is distinguished by its large dimensions. It is most often used by farmers in the fields. Mowing is done in even strips, with the grass neatly laid out in rows, which makes it much easier to collect.
- Segment mowers KS-F-2.1 are suitable for mini-tractors and walk-behind tractors. They are produced in Lyubertsy.
We buy a mower for a mini tractor
When purchasing this attachment, you should pay attention to:
- Correspondence of the number of internal connecting splines of the cardan with the number of external ones on the power take-off shaft of your mini tractor;
- Match the diameter of the mower's docking pins with the holes on the hydraulic lift rods of the mini tractor;
Even if something doesn't fit! We can also select a social adapter for the PTO and bushings to adapt the mower to any mini-tractor.
Features of the KS-F-2.1 mower
It works on flat and clean areas. It is unacceptable for stones and other solid debris to get into the mechanism, which leads to breakage of the cutting segments.
Such mowers have many positive qualities:
- high productivity, large width of the processed strip;
- possibility of working on compact tractors due to the low weight of the installation;
- low energy consumption, allowing to maintain the cost of production at the same level with small volumes of workpieces;
- Ease of Management. For it, one tractor driver is enough, without additional assistants;
- high quality of grass cutting work and long service life. At the end of the field work season, the device simply needs to replace the cutting blade.
The YuMZ, MTZ 80 and MTZ 82 tractors, and the more compact T 25 and T 40 tractors are most suitable for them.
This brand of mowers successfully works on the vast fields of collective farms and farmers. High demand is due to a variety of modifications, including:
- fingerless;
- with a cut called "Schumacher", made in Germany;
- with a hydraulic cylinder in the lifting mechanism;
- other options.
The most popular of them is the B4 model, which is distinguished by a more reliable frame, cutting tool beam, and increased reliability of the safety device. It is easier to make the necessary tilt of the cutting blade.
A class B model similar to it is lighter and is distinguished by the presence of mechanized lifting using a hydraulic cylinder, but it requires a more powerful tractor.
