The position of the fingers on the finger beam. the contradicting plate of the fingers should be located in the same plane to facilitate the installation of the required clearance in the cutting pairs.

Achieve a fingertips with a finger or setting adjusting gaskets between the fingers and the finger beam.

The distance between the fingers should be constant and equal to 76.2 mm. Permissible deviation of 3 mm.

The gap between the stops (shoulders) of the fingers. the gap should not exceed 0.3 mm. With a larger gap, the fastening of the fingers on the finger beam is weakened, which leads to an increase in the gaps between segments and fingers, as a result of which the quality of the cut of grass worsens. This can also cause a breakdown of a knife or finger. Eliminate the cutting of fingers without heating.

The position of the segments on the back of the knife. segments should be located in one plane. The permissible deviation at the vertices of the segments should not exceed 0.3 mm. Adjustment is achieved by the knife back, segments.

The position of the segments of the knife relative to the fingers. the gap between the cutting edges of the segments and fingers should be at the vertices of segments 0. 0.3 mm, and at the base of their 0.3. 1.0 mm.

With small gaps, premature wear of the segments and contradictory fingertips occurs, the resistance to the movement of the knife in the finger beam increases, which in turn leads to a breakdown of parts of the cutting apparatus and the mechanism of its drive.

Device

The model of a single-block KSF 2.1-b mitch consists of such main components as:

  • a metal frame, on which all other elements of the equipment are mounted and the mounting of the hitch to the power unit;
  • traction bar, connecting the cutting elements with a mowing frame;
  • working node with cutting elements (fingers);
  • a connecting rod connecting the cutting elements to the drive mechanism;
  • The unit drive consists of an exentric pulley, boxes, wedge belts and cardan gear.

When operating the unit, a canvas with cutting elements is brought into the progressive-offset movement of a parallel processed surface. The stalks of plants are pressed by moving blades to the motionless elements of the canvas and cut off, laying into the roll.

  • – head of the cutting element; 2 guide heads; 3 cover of the head of the cutting element; four internal shoe; 5 a divert rod; 6 external shoe; 7 field board; eight finger; 9 finger liner; ten segment of the cutting element; eleven press the cutting element; 12 the back of the knife; 13 friction plate.

Design features

Rotary mowers are used to clean herbs of any density and density. In addition, they are optimal for cleaning agricultural crops. Due to the adjustable height of the cut, the equipment is suitable for any plant species.

Please note that some models are equipped with weeds with a chopper, which allows the use of equipment for feeding.

All modifications presented on the market differ in the number of cutting elements covered by the area and the method of attachment to the tractor. Given that in farms, not a single tractor is used, but a tractor, mowers are classified as follows:

The cutting elements are located in the side, front or back of the mowing. The design of the equipment itself is quite simple: a support frame consisting of several segments with knives installed on them.

As the name of the equipment, the function of the knives is performed by discs (rotors). The force required for work is transmitted to the mitch through the tractor power shaft. A conical, wedge.reptable gear or cardan gear is used here.

Working effort is transmitted to the support wheel, which is setting in motion, gives the torque to the moment.

For agriculture, you should not purchase segmental mowers. This is a rather bulky equipment that is used to ennoble the territory. Rotor models have greater performance and can adapt to the relief and geometry of the field.

This type of attachment equipment is produced by Chinese, European and American companies. If you want to purchase high.quality and inexpensive products, we recommend that you pay attention to domestic and European brands.

Chinese braids are sold in a low price segment, but the assembly quality is sometimes left to be desired. American equipment is characterized by high quality assembly, but it is striking clearly overpriced.

Given these features, we will make a brief overview of rotary mowers that have earned positive reviews among farmers.

Bucking Rivets

High quality. affordable price

Given that the vast majority of farmers acquire tractors of the Minsk Tractor Plant, we give popular mowers on MTZ.

This is a widely used rotary mower in the country’s farms. From the features of the equipment, we can distinguish a flexible system of installation of rotors.

The cutting elements are able to change the plane to a corner of 45 degrees, which allows you to work in the fields with complex relief, without risk to damage knives. Four pair rotors are used here, which rotate in the oncoming direction.

  • The operating speed of the mower is about 15 km/h.
  • The weight of the braid is 535 kilograms, so it is suitable for working with tractors 0.9-1.4 traction class.

It is worth noting that the model is well balanced, equipped with reinforced gearboxes and complemented by a knife protection system from mechanical damage.

Such mowers are distinguished by an enhanced chassis and the use of steel gears in the drive system. This allows the equipment to withstand high shock loads not only during operation, but also during transportation.

The floating hitch provides accurate copying of the relief, reducing the load on the trailer tractor. The rotation of cutting discs of 3,000 rpm provides the mitch good performance.

It is worth noting that the installation of a vorothered apparatus is provided here, which provides uniform drying of the hay.

This is a Polish rotary mower that is fully adapted to climatic conditions. Two working discs are installed here, rotating at a speed of 540 rpm.

On the domestic market you can also find a more wide.sided modification. Wirax 1.85. There are no significant technical differences between the two Polish mowers.

Why did we bring these models? They differ in an affordable price, have a high margin of strength, unpretentious in terms of maintenance and repair. Given the small structural weight, such equipment can be aggregated even to a home-made mini-tractor.

The device of the braid

According to the principle of operation, the mowing mechanism resembles ordinary scissors. Cutting tools in it are triangles with sharp edges of rather large sizes (the so.called segments or fingers). By the name of the knives, the segment mower itself was called the name.

The device of the segment mowing

On one of the two metal bars, which consists of cutting canvas are stationary segments. The second, mobile bar, connecting with the motionless, presses and cuts the grass that has fallen between them.

In the cutting canvas are the heads of a knife, shoes, friction plate and clipping.

The canvas moves above the ground, capturing the plants at the same time by the width of more than two meters. The grass lies in a dump. The performance of the segment mowing is very high.

The cutting mechanism by means of a traction rod is associated with a frame, which is attached to the canal of the tractor. By the method of attaching to the tractor, devices are distinguished:

  • The frames on which the rest of the working tools take the base and which has a mount for installation to a tractor hitch.
  • Traction rod designed for the connection of the working cutting tool with the device frame.
  • Cutting canvas with sharp segments (fingers).

In the work of a mowing, a canvas with knives is brought into the progressive-dressing movement parallel to the surface of the earth. At the same time, the stems found in his path fall on the fixed segments of the canvas and immediately tightly pressed against them with mobile blades. The cut of herbs occurs like the work of ordinary scissors, leaving a strip of ready.made mowing.

Preparation of discs with knives

The second stage in the manufacture of a rotary mower for a walk.behind tractor is the preparation of discs with knives.

From the seeder you need to take 2 disks. 4 knives are attached to each of them. Knives are made of hardened metal. In order to save time and effort, you can use the rotor from the tractor. Only in this case it must be remembered that the length of the rotor should be reduced by about 4 cm. This will improve traction.

To fix the knives on the disk, you need to prepare holes. Each disc is drilled with a drill with a diameter of 6 mm. Knives are attached with shinka. For the proper operation of the device, a gap is left between the tire and the knife, the height of which is a couple of millimeters (1-2 mm) more than the thickness of the knife itself. In addition, the gap will allow you to perform 2 nuances at once. Knives will rotate 360 ​​degrees. Due to this, when hitting something is firm, the knife will turn, but it will not break. During the rotation of the disk, centrifugal force will be created. Under its influence, the knives will deal and cut the grass.

Knives are fixed on the axis. It is made using carbon steel. And it is not recommended to make the axis too thin. The minimum axis diameter should be 0.8 cm. To avoid unnecessary free rotation of the knives, the axis is delayed until it stops.

Connection of parts

Когда все отдельные запчасти роторной косилки к мотоблоку собраны, их можно соединять вместе. Discs join the finished frame. After that, a connection shaft of the power of the walk.behind tractor and working elements is carried out. In this case, it is necessary to clearly observe the direction. They should rotate in different directions, that is, towards each other. This is done with the purpose that the mowed grass develops in a row, and not scatter throughout the site.

In the manufacture of a mower it is very important that the fastening of all elements is reliable. When mowing, the disks rotate at large speeds. In the case of a breakdown breakdown, the parts will scatter in different directions. They can hurt others.

Disadvantages of the device

Naturally, a segmented mower for the tractor has certain disadvantages:

  • No matter what area such a device processes, its capabilities are limited.
  • The speed of work is quite small, which does not allow you to cope with the task quickly. At the same time, it is not possible to increase the indicator.

In principle, these are all significant disadvantages of the device.

Technical characteristics of the unit

So, you already know the device of a segment mower. Now you should deal with the technical characteristics of the product:

  • The weight of the apparatus: 120 kg.
  • The working width of the strip that the device can capture: from 20 cm to 2 m.
  • Speed: per hour can be processed about 1-2 ha of fields.
  • Minimum mowing height of grass: 5 cm.

Only one machine operator can control such an apparatus.

Mechanism of balancing and lifting

The mechanism is designed to limit the pressure of the beam of the cutting on the soil and to transfer the mowing to the transport position. Mechanism (see. Figures 6 and 7) consists of hydraulic cylinder 1 connected to the bracket 2 and a hitch frame 3.

The tension bolt 6 allows you to adjust the pressure on the soil of the ski located at the beginning of the cutting timber.

The connection of all links of the balancing mechanism on the axes provides a free turn of the beam of the subframe cutting in the trunks.

In the transport position of the mowing, the links of the balancing mechanism are fixed by the counter 7 (see. Figure 6) and screed 10, fastened with a cord with a spring 11 and transport thrust connecting a subframe 13 with a cutting beam 14 (see. Figure 7). Stand 7 is equipped with two oval grooves. In the transport position of the mowing, both grooves should be located inside the screed 10.

Aspects of the device

This tool is hinged and attached directly to the tractor itself, which moves it. Has this kind of tool with a capture, the width of which in most models is 2.1 meter. Also, its “composition” includes a cutting finger special apparatus. If you prefer the unit of more compact sizes, then we suggest you familiarize yourself with a mechanical hand lawn, which is many times less than this tool and can be used without a tractor.

By means of the use of the rod of the traction direction, it is attached to the frame itself, which is located on the tractor, after which it is fixed with the help of the so.called Sprenhel to the tractor itself.

The mower also has the so.called “fingers”. The name of the cutting direction, and which actually perform the main purpose of the device, wear this name.

As for the knife that is located on the device, it consists of a specific strip, head, as well as peculiar segments. It is worth noting that his movement is reputed-progressive, that is, directly from the tractor itself passes through the box of the leading pulley, the transfer of the cardan, eccentric-chip, as well as the transmission of the cuneiform, after which it returns through the same axis.

Before starting to operate the mowing with the help of the cutting apparatus, namely, its finger socks are pulled by pulling the cord. After that, a special laying is placed, it is between the fingers and the beam. Do this until a continuous straight line for a trimmer is formed. However, due to its fixed position over the soil, the unit cannot be used on the landscape of different heights, therefore, for work on a more complex site, it is better to choose special mowers for high grass and uneven areas.

Segment CSF 2.one

Segmented type KSF-2 braids.1 are produced by Lyubertsy (this enterprise is the successor of the Ukhtomsky factory and the successor of its long.term business. the manufacture of haying equipment of various types and structures.

Appointment

KSF-2.1 perfectly cope with mowing work mainly in the flat territories. they mow different.type herbal crops with laying plant mass to mowing:

The braid is applicable for planning mowing in the territories of almost any climatic zones. it provides a trouble.free work with the exception of only semi.desert and desert sections.

Advantages and disadvantages

In addition to using in any weather conditions, segmented KSF-2 mowers.1 possess a number of other advantages for which they are appreciated by many business executives:

  • High performance, achieved by a relatively high speed and a large width of the simultaneous capture-more than 2 meters.
  • The light weight of this hinged mowing equipment allows you to work with it even on small types of transport devices.
  • The small energy intensity of the device will help save money and does not affect the increase in the cost of hay with a decrease in the volume of the workpiece.
  • Simple control without connecting hydraulics does not require additional maintenance personnel, except for the operator of the drain tractor.
  • The economy of the acquisition of the device itself and spare parts for it, available everywhere.
  • High.quality work at high speed and a long service life. by the expiration of the period of operation, it will be enough to change the cutting canvas, and the braid will again be ready for the foul season.

ATTENTION! The disadvantage of the device is its exactingness to the cleanliness of the processed area, since the ingress of stones, wood or metal objects can disable it (breakdowns of segments, etc.P.).

The device of the braid

According to the principle of operation, the mowing mechanism resembles ordinary scissors. Cutting tools in it are triangles with sharp edges of rather large sizes (the so.called segments or fingers). By the name of the knives, the segment mower itself was called the name.

On one of the two metal bars, which consists of cutting canvas are stationary segments. The second, mobile bar, connecting with the motionless, presses and cuts the grass that has fallen between them.

segments, mowing, segment, mower

Achieve a fingertips with a finger or setting adjusting gaskets between the fingers and the finger beam.

The distance between the fingers should be constant and equal to 76.2 mm. Permissible deviation of 3 mm.

The gap between the stops (shoulders) of the fingers. the gap should not exceed 0.3 mm. With a larger gap, the fastening of the fingers on the finger beam is weakened, which leads to an increase in the gaps between segments and fingers, as a result of which the quality of the cut of grass worsens. This can also cause a breakdown of a knife or finger. Eliminate the cutting of fingers without heating.

The position of the segments on the back of the knife. segments should be located in one plane. The permissible deviation at the vertices of the segments should not exceed 0.3 mm. Adjustment is achieved by the knife back, segments.

The position of the segments of the knife relative to the fingers. the gap between the cutting edges of the segments and fingers should be at the vertices of segments 0. 0.3 mm, and at the base of their 0.3. 1.0 mm.

With small gaps, premature wear of the segments and contradictory fingertips occurs, the resistance to the movement of the knife in the finger beam increases, which in turn leads to a breakdown of parts of the cutting apparatus and the mechanism of its drive.

With large clearances, a deterioration in the quality of the cut occurs, which can cause an increase in the height of the cut and shortage of the harvest of grass.

Achieve the necessary gaps with fingertips. The gap on the base of the segment is often reduced to an unacceptable value due to wear of friction plates. In this case, friction plates are rotated by 180 degrees. (if they are current) or replace with new.

The position of the guide head of the knife. the gap between the heel of the knife head and the guide should not exceed 0.3 mm. With a larger gap on the surface of the field, the inner shoe remains untied stalks of grass. Adjusted using gaskets.

The position of the knife snouts. the gap between the presses and segments should not exceed 0.3 mm. With a greater gap, the quality of the cut of plants deteriorates, and when the segment is stressed, their working surfaces wear prematurely and the resistance to the knife movement in the finger bead increases. Regulated by the bend of socks of squeaks or using adjusting plates installed between squeezes and friction plates.

The position of the friction plates. the friction plates should touch the segments. Achieve bending them or using gaskets installed between friction plates and a finger beam. Permissible gap of not more than 0.3 mm. Friction plates should touch the back end of the knife back. Adjusted by the displacement of friction plates due to the increased diameter of the holes for the mounting bolts. In the presence of a gap, the quality of the cut of plants worsens and a breakdown of the knife back in this place is possible due to the appearance of fatigue phenomena due to multiple excesses.

The centering of the knife. in the extreme positions of the knife of the middle of the segments should not reach the middle of the fingers on both sides by the same value, t.to. The knife move is less than the distance between the fingers. The permissible deviation should not exceed.3 mm. Violation of this condition leads to a deterioration in the quality of the cut of plants from that side of the finger, where the segment does not reach the magnitude larger than it should. Achieve a change in the length of the connecting rod.

The crossing of the segments towards the external shoe is not allowed, t.to. When setting the cutting device in the transport position, the connecting rod will become a spacer and it will be impossible to raise a vertically fingers.

Removing an external shoe. the cutting device should move in frontal in operation. This is achieved by removing the external shoe forward within 35. 55 mm (along the fingers) with a non.working mower. Then, in the work, all dead gaps in the joints of the suspension mechanism will be selected and the cutting device will be located frontal. It is achieved by a change in the length of the stretching (sprengel), as well as the turn of the finger beam using an eccentric sleeve.

Features of operation

The mower is mounted to the tractor with fixation of the longitudinal rods of the tractor of the hitch, setting the distance from the ground to their rear ends about 40 cm and as a rise of not more than 65 cm. This is done for the impossibility of the side shift of the braid frame relative to the central axis of the drain unit.

In working with the device, the rules that contribute to long.term and safe operation should be followed:

  • The cutting apparatus of the braid should be covered by a protective casing.
  • The tractor stopped with simultaneously putting the power shaft of capacities.
  • All settings and treatment work with the mowing itself and especially cutting tools are carried out when the tractor is completely stopped and plug.
  • Transportation of the device is carried out with a protective shield on its teeth.

IMPORTANT! The most adapted for working with segmented mower mowerpower KSF-2.1 Types of MTZ 80 and 82, YUMZ, as well as more compact T-25 and T-40 units are considered.
