EasyCut II Kits

To complete the work you will need:
– small grinder;
– Drill (preferably low-speed);
– Spanners.

1. Work begins with the installation of fingers and friction plates. The thickness of the bar is 11 mm, we install the friction plates of 6 mm, so that the back of the knife when the mower is working goes along the friction plates, and not along the bar. For this size, use 17 mm anti-roll pins.

2. From the drive side, for free passage of the knife head bar, two double reinforced open fingers are installed (photo # 1), then double closed fingers. The last to be set is a triple closed finger. Knife manufactured by Gebr.Schumacher, modular consists of a knife head, a knife back, 2.4m each. The total length of the blade back depends on the length of the mower bar and is cut on site. The knife head is attached to the knife back with bolts 618, and the segments with a special toothed bolt 616 and an M6 flange nut.

3. In the knife head we drill holes with a 10 mm drill to a height of 6.5 mm for the M6 ​​press-in nut, on which the knife back and segments will be attached (photo # 2, # 3).

From the side of the knife head, the first two segments are set with a notch up. A stripping segment is installed at the end of the knife.

4. On the inner shoe of the mower we put two anti-shearing plates, and under them a lining (photo no. 4), which we attach to the shoe with rivets 5 mm in diameter (photo no. 5).

5. Remove the upper surface of the outer shoe with a 3 mm grinder. In the place where the shear plates will be attached (photo no. 6). Then we install a lining between the two plates and drill an additional hole with a diameter of 5 mm. Cut off the guide spout on the top plate, and then rivet to each other and to the shoe (photo # 7).

6. Place an adjusting plate (photo no. 8) under the front guide of the knife head of the inner mower shoe, and under the rear guide. Friction plate (photo # 9).

7. Insert the knife from the side of the inner shoe. Replace the front and rear rails and tighten the bolts. If the knife head clamps, then put 1 mm adjusting plates under the guides (photo No. 10).

8. The whole system is ready for operation. Before the first test, it is recommended to lightly lubricate the cutting mechanism with used oil.

Mounted mower KSF-2.1 Maintenance

A segment mower, like a tractor, needs periodic maintenance. During the operation of the mower, the following types of maintenance are carried out: maintenance performed every shift or shift maintenance (ETO), maintenance number 1 (TO-1), maintenance number 2 (TO-2), and maintenance performed at end of the season of work (TO-S).

The need for daily maintenance arises every 8-10 hours of mower operation. Service number 1 should be done after 60 hours, and service number 2 should be done after 120 hours of operation. Seasonal maintenance is required after the end of the cleaning season.
In terms of time, ETO takes 15-20 minutes, on average, it takes at least 1.1.5 hours to carry out TO-1 and TO-2, and at least 1.5 to 2 hours to carry out TO-S.

During the every shift, the following types of work are performed. First, it is necessary to clean the mower components from dirt, dust and plant residues. To do this, you can use a rag or brush. Further, you should make sure that the fasteners of the cutter bar pins, transport rod and connecting rod are secure. Threaded connections must be tightened tightly with a wrench. Then, it is required to visually check the technical condition of the knife and, if necessary, either sharpen it on a grinding machine, or replace the broken knife with a new one. The next step involves checking the clearances between the bushings and the segments, and, if necessary, adjusting them. The final step of the shift-by-shift maintenance is the lubrication of all units of the cutter bar (friction plates, knife clamps, front and rear cutter head guides), connecting rod bearing and cardan drive bearings. As tools at this stage, use a liquid lubricator and a lever-plunger syringe.

During TO-1, all the work carried out at the stage of every shift maintenance is first performed, then the pressure of the mower shoes on the soil is checked. The pressure of the inner shoe on the soil must be at least 200-300 N (20-30 kg). The pressure adjustment on the inner shoe is made by tensioning the spring with a bolt. On the outer shoe, the pressure should be 100-200 N (10-20 kg).

The pressure is adjusted by rotating the lever in one direction or another, after removing the hairpin. Next, you need to tighten the V-belts. The next step is to check and, if necessary, adjust the mower cutterbar in relation to the connecting rod and the tractor. In the working position, the line running along the axis of the connecting rod should be parallel to the axial mowing line of the knife when viewed from above. It is possible to adjust the relative position of the connecting rod and the knife by means of the eccentric bushing (small eccentric K-2010) located in the hinge of the inner shoe. To do this, you need to: unscrew the bolt, turn the bushing (eccentric) in the desired direction and install the bolt in another hole.

Adjustment of the inclination of the cutter bar is achieved by means of a grooved washer, by moving it to different reefs within the elongated hole, it is possible to adjust the angle of inclination of the draw bar joint, which is connected to the cutter bar. When the grass is lodged, it is recommended to tilt the cutter bar slightly forward so that the cutter bar fingers sink into the grass and lift it up. When working on uneven ground, it is recommended to tilt the cutterbar back slightly to avoid hitting the mower’s fingers with the ground and letting stones pass from below. The final maintenance step # 1 is to lubricate the drawbar axle, front arm axle, vertical arm axle, thrust arm axle using a grease nipple and a plunger lever.

During maintenance number 2, perform all the stages of the shift and first maintenance, and also lubricate the eccentric pin bearings using a lever-plunger syringe.
During the seasonal maintenance, all regular maintenance operations are performed, then the shaft bearings in the frame and the drive pulley shaft bearings are lubricated. At the final stage of seasonal maintenance, the mower is prepared for long-term storage in accordance with the recommendations.

European technology

The goods, which are received in European countries, can boast of their quality characteristics. But this statement has not received an accurate statement or refutation to this day. But in practice, the matter will be arranged in such a way that the segment mowers of the European assembly are invented in accordance with all standards.

The most popular is the manufacturer Al-Ko. These products are imported to all European countries. The reason for this demand is due to the fact that mowers have already won the hearts of many consumers. Of course, the cost of European products will be higher than Russian ones. The average price of a segment mower reaches 30,000 40,000 rubles. But today people have begun to stick more to quality characteristics than price.

Tractor t 70s technical characteristics and other technical data are indicated in the article.

Manufacturers and prices

To date, the following manufacturers of segment mowers are in great demand in Russia: Strizh KNS-0.8 and Mobile KM-0.5. The presented models are produced by Moscow Avtomash. Names, the products received by this manufacturer are in the widest demand.

What is the consumption rate of fuels and lubricants for the MTZ 82 tractor, you can find out by reading the article.

This model is characterized by compact size and ease of use. Since the size of the unit is small, it is in great demand among gardeners and summer residents. The weight of the equipment is 25 kg. The segment mower of this model is capable of mowing grass, the height of which is 0.5 cm. If the height of the plants is small, then the mowing process will be ineffective.

The article indicates the price of attachments for MTZ 82.

Characteristic of KSP-2.1

The production process of this mower is carried out by Bobruiskagromash. This company is located. The segment mower can be used in a wide variety of areas, but there should be no stones or bumps there. Otherwise, the segment mower will stop functioning.

The mowing process can offer the removal of both natural and seeded vegetation. These models can have a thrust of at least 0.6 and no more than 1.4. Thus, the power of the tractor equipment is not serious.

The mower is activated using the tractor PTO shaft. The mower can reach a height of 40-80 mm. This allows it to be used for cutting very tall grass. If we consider the speed of work, then the unit operates for about 12 hours. The product is 0.9 m long, 1.2 m high and 2.3 m wide.

Mower mechanism adjustments

Before starting the mower, it is necessary to carefully check the correctness of assembly, adjust the mechanisms, and turn them manually.

Adjusting the position of the knife in the cutterbar.

Before operating the mower, check the reliability of the fastening and the location of the fingers on the bar. It is very important that the finger guard is in the same plane. Their position is checked using one or two cords stretched over the tops or bases of the counter-cutting plates. All shear plates should be in contact with the tensioned cords. Curved fingers are straightened with a special key or light hammer blows.

For reliable cutting of the stems, the segments must be in contact with the counter plates in the front, and at the rear base have a clearance of 0.3-0.5 mm. This is achieved by bending the knife clamps and extending the friction plates. In this case, the gap between the knife clamp and the segment, as well as between the knife back and the friction plate should be within 0.3. 0.5 mm. With the specified gaps, the knife should move easily, and the knife head should not have play in the guides.

In the extreme dead positions of the knife, the axial mowing line of the segments and fingers must match. This adjustment (centering of the knife) is done by changing the length of the connecting rod. If the apparatus is not centered, then due to a decrease in the speed of the knife in the cutting zone, the segments do not cut off part of the stems and tighten them between the segments and fingers. The deviation of the center lines of the segments from the center lines of the fingers is allowed within 3.5 mm, depending on the design of the mower.In high-speed mowers KS-2.1, the distance between the axes of the segments and fingers is 76.2 mm, and the knife stroke is reduced to 68 mm for the purpose reducing the forces of inertia during its operation. Therefore, in the extreme right position of the knife, the middle of the segments should not reach the middle of the fingers by 5 mm.

Adjusting the inclination of the cutter bar.

When mowing plants on uneven soil, the cutterbar is tilted back to avoid digging into the ground. When the herbage is lodged, the cutterbar is tilted forward so that the fingers do not crush the grass, but lift it. The cutter bar is tilted by rotating the hinge relative to the drawbar.

Adjustment of the cutting height of the grass.

The cut height within 5.7 cm is set by rearranging the runners of the inner and outer shoes. When adjusting, the agrotechnical requirements for the cutting height and the condition of the soil surface are taken into account.

Adjustment of the position of the cutter bar in relation to the connecting rod and the tractor.

For normal operation of the mower, it is necessary that the cutting unit is parallel to the axis of the rear wheels of the tractor. In this case, the knife and the connecting rod work in the same vertical plane. However, under the pressure of the cut grass and in the presence of gaps in the hinge joints, the mower retracts the cutterbar. Therefore, before the operation of the mower, the outer end of the finger bar is brought forward by 35.55 mm relative to the inner end (running of the cutter bar). The required run is set by turning the eccentric sleeve. From by simultaneously changing the length of the sprengel. At a mower mounted on a tractor, the race is checked against a straight mowing line parallel to the axis of the rear wheels of the tractor, through the nose of a finger located next to the inner shoe.

When drilling holes in the pivot eyes and inner shoe, or when the pins connecting the hinge and shoe are worn, the outer end of the cutter bar moves back. The apparatus is returned to its original position by turning the eccentric sleeve to the left.

The tension of the drive mechanism belts is adjusted by moving the drive pulley with the tension screw.

Adjusting the shoe pressure on the ground.

The stable movement of the cutterbar is ensured by the optimal load on the inner and outer shoes. At low shoe loads, the cutterbar bounces on uneven terrain, while heavy loads cause the shoes to burrow. The optimal loads are considered: on the inner shoe 350 450 N, and on the outer 90 150 N. The load on the shoes is checked with a dynamometer, and is regulated by the tension of the compensation spring.

Lifting mechanism adjustment.

When lifting the machine with a tractor hitch, the inner shoe should lift off the ground approximately 100-150 mm earlier than the outer shoe. This is achieved by adjusting the lifting linkage. Before adjusting, release the compensation spring tension.

The lift height and the stability of the cutterbar movement on the ground depend on which hole in the connecting bar is used to connect the front lift arm. When working with tractors T-25, the front arm must be attached to the lower hole in the bar. When working with tractors MTZ to the middle, and when working with other tractors to the upper hole.

Installation of the field board.

For reliable separation of cut and uncut grass and cleaning the path for the passage of the inner shoe of the cutter bar during subsequent runs, it is necessary, depending on the height to entangle the grass, to bend the two upper rods of the field board.

When converting a mower for mowing leguminous crops, remove the cutting unit from the mower and replace it with the cutting unit of the device together with the VAL-KO forming grid. A stem lifter is attached to every third finger. The angle between the soil surface and the upper edge of the stem lifter is set within 1516.

Construction device of a self-made segment mower: drive of the mower from the PTO of the tiller

To do do-it-yourself segment mower for a tiller it is necessary to make the lower (table) and upper (segment) of the homemade mower. To do this, you can use a steel strip to which the triangular teeth of a homemade mower must be riveted. The teeth are cut from strong alloy steel and sharpened, alternatively, the teeth can be cut from ordinary steel (then this can be done directly on the steel strip), but in this case they must be well hardened to increase wear resistance. On the lower part of the tiller segment mower, the so-called table, guides are installed, which can also be made from steel strip. The upper part is installed in them, which is attached to the drive. The mower is driven by an eccentric shaft attached to the power take-off shaft (PTO) of the tiller, which converts the rotary motion into a reciprocating motion of the upper part of the segment mower relative to the table, as a result of which the teeth of the segment mower seem to move relative to each other (something like scissors) and the grass stalks are mowed between the teeth. This is the simplest design of a home-made segment mower for a tiller, as it consists of a minimum of component parts, which also greatly simplifies the adjustment and adjustment of the blades. In the device of a segment-finger mower, the knives are set in motion by means of a finger bar, which significantly complicates the entire design and the possibility of adjusting the knives of the segment mower. Segment mower drive can be simplified if you spring the upper cutting segment, then it will be enough to install a pusher on the drive pulley, which at each revolution of the drive shaft will move the cutting segment set in segment mower guides to the extreme position, and the spring will return it to its original

Device

KSF-2.1 mower consists of the following main structural units and parts:

  • A frame on which the rest of the working tools are taken on the base and which is fastened for installation to the tractor hitch.
  • A pull rod designed to connect the working cutting tool with the device frame.
  • A cutting blade with sharp segments (fingers).

In operation of the mower, the blade with knives is set in a forward-reverse motion parallel to the ground surface. In this case, the stems encountered on its way fall on the fixed segments of the canvas and are immediately firmly pressed against them by the movable blades. The grass is cut in a similar way to the work of conventional shears, leaving behind a strip of already finished mowing.
