Rotor mower for the MTZ tractor: device, maintenance

Depending on the size and configuration, the segment mower is used as a trailer equipment for gasoline and diesel engine, a wheel and caterpillar tractor. It is used for cultivating the adjoining territory, primary processing of virgin and abandoned areas, hay harvesting with laying into a roller for the needs of the subsidiary farm. Small farmers conduct mowing grain crops. In terms of quality and performance of work, these devices surpass the analogues of rotary and drum type.

The rotary mower to the walk.behind tractor is a type of attachment equipment, the function of which is to mow weeds and bushes in meadows and fields. This device successfully copes with the removal of grass in large areas, the soil of which is not treated with herbicides. Often, the rotary mower is also called disk. this is due to the principle of its operation and constructive features. Depending on the method of connection with the walk.behind tractor, such a mower can be half.waist, hinged or trailed. Also hinged equipment of this type is classified by the location of the cutting elements in relation to the used motoblock. Therefore, the factors distinguish rotary mowers with the front, rear and lateral arrangement of cutting knives.

During operation on the site, the rotary mower is set in motion through the transmission and wheel of a motor block. The design of such attached equipment is extremely simple. one or more cutting discs along with the support wheel are fixed on the frame. As soon as the support wheel begins to move, the discs that make the mowing of vegetation begin to rotate with it.

Areas the use of rotary mowing is quite extensive. it can be used in pastures, meadows and large gardens. At the same time, the more discs are included in the design of the equipment, the greater the processed area can be.

Traction transport

Traction transport (see. Figure 17) is designed to fix the cutting beam in the transport position when the tractor moves or when storing a mower.

bar; 2. fixator; 3. ear; 4. finger; 5. countrogayka.

It consists of a bar 1, on the left end of which a latch 2 with the right thread is plunged, and on the right is the ears 3 with left threaded.

Transport traction is attached to the axis of the subframe. The presence of threads of the opposite direction on the frame allows you to adjust the length of the traction when rotating the rod.

In the working position of the mower, the finger 4 is inserted into the hole of the latch 2. In the transport. in the hole on the beam of the cutting rotation (see. Figures 2 and 7).

The purpose and technological process and adjustment of the rotational mowing KRN-2,1

Rotation mowel is designed to mow high.yielding light grass (yield of more than 150 c/ha) weeds, and small shrubs at high speeds (9. 15 km/h) with laying the beveled mass in the wrap. Capture width 2.1 m, performance at 15 km/h 3.15 hectares. Rotor speed. 2040 rpm, mass. 570 kg.

The cut of the stems is carried out with the help of plate knives, articulatedly fixed on pair of rotors rotating towards each other one (Figure 2). The knives cut the grass according to the principle of a reckless cut and taken out of the cutting zone, moving it over the cutting timber. The trajectories of the knife of the knives of neighboring rotors are overlapping, providing high.quality mowing.

Small grass is laid in the wrap, and the field divider shield ten Freezing the place for passing the tractor wheels at the subsequent passage (the bums remain between the wheels of the tractor).

A traction fuse is installed on the mower eight, intended for warning from the breakdowns of the cutting apparatus at the time of collision with an obstacle. When impact on the obstacle of the wedge, the latch leaves the hook and the mower turns around.

The operating bodies of the working bodies are carried out from the tractor via through the cardan gear 7 to the shaft of the leading pulley of cunelar gear and further through the gearbox through the gear cylindrical transmissions located in the oil.bath of the beam, the rotors are rotated one With knives.

A overtaking coupling is mounted on the shaft of the leading pulmonary gear pulley, designed to provide idle of the rotors at the time of turning off the power selection shaft of the tractor.

The main adjustments of the KRN-2.1. The axis of the hitch of the braid (lowered on shoes) should be at a height of 485 mm ± 25 from the ground and in this position it is necessary to adjust the tension device of the mechanism. It is balanced so that the pressure of the inner shoe is 300 700 N, and the external one. 100 200 N, depending on the density of the grass.

The cutting device should be in a horizontal plane and in operation should be based on the soil with shoes. This is achieved by a change in the length of the upper traction tractor. If necessary, a slope of the cutting device forward in the direction of movement within 3 7 degrees is allowed.

The tension of the wedge belts is carried out using a stretch bolt until the spring turns are contacted. Secondary pull.ups of nuts are carried out when the gap between the turns of the spring will increase to 3 mm.

The traction fuse is adjusted by tightening the spring nuts so that the fuse is triggered with an increase in 300 kg attached in the middle of the cutting apparatus.

Check the mounting of the knives of the cutting apparatus every 4 hours of operation, and the replacement of them is carried out only after preliminary stopping the rotor through the holes in its ring part.

Attention! During testing, starting and work, unauthorized persons are prohibited from being closer than 50 m at 3 0 and 90 100 m with 7 0 tilting the cutting device forward in the direction of the machine.

The preparation of a tractor hinged system for working with a mowing must be carried out in the following order: adjust the central traction so that its length is 800 mm; adjust the braces so that you can put on the hinges of rods on the axis of the frame; turn on hydromechanism and install the rear ends of the longitudinal rods so that the holes in spherical hinges are at an altitude of 485 mm.

For the MTZ-80 tractor, equipped with a positional regulator, the location of the longitudinal rods (485 mm) is achieved by summing up the limiter’s flywheel to the slot of the regulator control sector.

What material should be used when installing a home.made mowing?

The main material intended for the manufacture of home.made mowels is scrap. Here you can use absolutely everything. It can be frames from old bicycles or unnecessary spare parts from the car. Rusty frames that can be found on an abandoned farm are ideal for the foundation of the future device.

In addition, you can inspect objects in your yard, where an old metal barrel or battery can also be useful for the manufacture of equipment, such as a home mower for a mini-tractor. The most important point in this work is the presence of qualified specialists, some knowledge of the technical part of this issue and good knowledge of the welding machine.

How to adjust the one.Bruska to the mower correctly

High-speed CS: GO-2,1 mower

CS: GO-2.1 single-Brusary mower is hung on the tractor from behind according to a three-point scheme. The main working body of the mower is the cutting device.

It is pivotally attached to the frame of the mowing with a traction bar and is held in the working position with a Sprenhel. The drive to the cutting device is carried out from the tractor’s cardan shaft using an exentric pulley, wedge-rephid gear closed by a casing, and a box of a leading pulley.

The rise of the cutting apparatus is carried out by the hydraulic mechanism of the tractor through the system of rods and levers.

The cutting apparatus consists of a finger beam and a knife that makes reciprocating movements. The finger beam is a steel elastic strip to which cast fingers are attached with bolts. In the upper part, the finger has a process, on the sides. antennae, and in the back. a burto.

Antennae and bucks prevent the turning of the finger during operation.

Steel plates with sharp side faces, called contradictory plates are attached to the fingers.

The knife consists of a back in the form of a steel strip with a cross.section of 20×5 mm, to which steel plates with sharp side faces are attached. segments and a head with a hollow ball. Rods of connecting rod cover the ball and form a ball joint.

During cutting the stems, the knife back is tightly pressed against the finger beam and wear out quickly. To reduce wear, to the finger beam every 38 cm, friction plates are attached. As the plates are worn, they are mixed forward due to the fact that the diameter of the holes in the plates is larger than the diameter of the fasteners.

Rights fixed above the knife press the segments to the contradictory plate of the fingers.

The finger beam is installed on two shoes: internal and outer, which hold it at a certain height from the surface of the field. Under each shoe there is a shell, the rear end of which can be lifted and lowered, adjusting the height of the cut of mass.

Medical adjustments pursue the goal of the most complete cutting of mass without pollution of its soil. First of all, the gap between the segments of the knife and the anti-cutting plates of the fingers of the cutting apparatus is regulated. To do this, the knife is removed, the cord is pulled along the socks of the fingers and by installing the gaskets between the finger beam and fingers, so that the socks of the latter are located on the line of the stretched cord. Then the knife is installed, the gap is checked and, if necessary, with light beats of the hammer, clamping paws are bent. At the same time, they achieve that segments with socks touch the contradictory plates, and the grounds. friction plates. After adjustment, the knife should move easily, without jamming. In the extreme positions of the knife of the middle of the segments and fingers should coincide. This adjustment is carried out with a shift in the knife by changing the length of the connecting rod.

The slope of the cutting apparatus is regulated by turning the traction rod depending on the relief of the field and the state of the mass. If the field relief is uneven, fingers raise. With a killed mass, they are tilted down.

To protect the drive connecting rod from the breakdown, it is placed on the same line with the cutting device. To do this, in advance by a change in the length of the sprenigel, the outer shoe is carried forward relative to the internal shoe by 35-50 mm. During operation under the action of the load, the cutting device moves back and is located in the same plane with a connecting rod.

The pressure of shoes on the soil should be: internal. 35 kgf, external. 8-15 kgf. Regulate it with a change in the tension of the compensation spring. If the pressure on the shoes is more than these values, then they unload the soil that clogs the cutting device and worsens the quality of the cut. With a lower pressure of shoes to the Earth, the required height of the cut is not provided.

Design features

Devices produced by different companies can vary in external and some technical data. The principle of the functioning of such units is identical and dictates an integral list of nodal blocks included in the design.

Standard rotary braid for grass is made of:

• frames;
• subframe;
• balancing mechanism;
• cutter;
• field divider;
• traction fuse;
• racks;
• protection of the cutting apparatus.

Frame. element designed to attach the nozzle to the walk.behind tractor. Has two axes facing the sides. One of them serves to fix the frame on the lower rods of the leading apparatus. The second is attached to the second from the overload of the rod holding due to bolts and two nuts. An element with a bracket will join the frame, which allows you to install a subframe.

The subframe is a welded part connecting the frame and cutting element. It consists of a rectangular case. On the one hand, the tube with bushings introduced into it is welded. In the middle there are “ears” designed for fastening transport traction and device that regulates the height. The side of the bracket is on which the traction fuse is attached to. On the subframe, the drive itself and the protection of the belt transmission are fixed.

The balancing mechanism is designed so that the cutting device repeats the terrain relief. Thus, the best mowing of vegetation is achieved. Using this mechanism, the mower is also converted into transportation mode. Its adjustment is carried out by special tension bolts.

Cutting device performs mowing. Its body serves as a whole crankcase. The cutting elements are based on the soil through a special pallet installed below. The cutting device can have on its body how much rotors. There are usually two of them in the motoblock modification. Rotors are equipped with two knives. The transmission of mechanical effort from the motor to knives occurs by means of a belt of traction, gearboxes, a number of shafts and gears.

Field divisor helps to separate mowed and dwarf grass. It consists of their shield, springs and bolt fasteners. The spring mechanism allows the divider to move back at the time of overflow of the cut vegetation.

During the mowing process, the cutting mechanism may come across an obstacle. In order to avoid a breakdown in this situation, the rotary mower is equipped with a traction fuse. Using this node, a braid for grass can deviate from the working position to the moment established by the user.

The stand helps to hold the hinged unit in a convenient position at the time of its connection to the walk.behind tractor.

The assembly knives rotate at high speed. For the safety of a person using equipment, they are placed in a protective casing. It can be made of light metal or tarpaulin fabric.

Various modifications of rotary braids can differ in the presence of certain details. Some of them can be purchased, and others are made independently.

Service and storage

The duration of the uninterrupted operation of the mechanism of a motor.block braid for grass directly depends on regular maintenance. Within the framework of the service work, the device is cleaned from herbal residues, dirt and dust. The degree of tightening of the threaded joints is checked. the weakened are pulled up. The tension of the belt is measured. Knives of the cutting mechanism should be sharply sharpened. To do this, they must be periodically removed and undermined. In a hinged position, it is forbidden to do this. Adjustment of the balancing mechanism is carried out after each fact of operation. Its spring part is checked and regulated.

Details of nodes subject to high friction are subject to regular lubrication. The conical gearbox, the section of the cutting timber and bearings, especially need it, especially. Lubrication is carried out only through the corresponding oil openings.

It is not recommended to pour oil or apply thick lubricating material in the rubbing areas not equipped with oil.liner traffic jams. This will lead to the sticking of dust and dirt in greased places, increase the degree of wear of parts and reduce their service life.

The procedure and list of works carried out for preparation for long.term storage is determined by typical characteristics. The main nuances of such preparation include cleaning of dust and dirt, removal of moisture from metal surfaces, coating parts with special anti.corrosion solutions. An important factor is the right choice of suitable storage location. It should be dry, protected from mold, drafts and other aggressive influences.

Additional information on how to prepare a rotary mower for the off.season storage is in the operating instructions from the manufacturer.

The CS: GO-2.1 mower is designed to mow natural hayfields and seeded herbs in all climatic zones, except for deserted and semi-deserted zones. Segmented mowers are widely used in farm and collective farms for harvesting high.quality hay and cereal herbs. Small mass of the csinel CS: GO-2.1 and low energy intensity (up to 4.0 kW.) allow you to aggregate it with a wide tractor train-T-25; T-30; T-40; MTZ-80; YUMZ-6. The working organs of the segment-paltz type include standardized steel fingers 5k GOST 19777 and the segments of GOST158. Download electronic catalog of details of the KSF 2 braid.one

The agricultural complex production and trade base is engaged in the production of hinged segmented mowers CS: GO-F-2.1 with a hydraulic cylinder and hinge lifting mechanism. Our segment mowers CS: GO-2.1 cooked made of high.quality metal, have a strong welded frame, at the request of our customers, we made a number of changes for an example of the modernization of the connecting rod, the production of which you can see the connecting rosm 16.000. As elements of a spinning mowing mowing, we use a strong cutting device of the length of which is 2.1 meters. The cutting device is not welded, it is a steel beam that has a large shoe on the one hand, for fastening the cutting device directly to the frame. On the other hand, a small shoe is installed, with a sole.adjustable sole of the sole of the baashmak. On the cutting apparatus of the haymaking of the KSF-2.1 The main working bodies and often replaced by expenditure kites are the fingers of the cutting apparatus of KNMM 19301 or KNNM 08.010, Knm knife 08.040 and clipping knife. In the braid drive, we use only high.quality bearings. On the segment mitch CS: GO-2.1 installed many details of cast iron casted from cast iron and the production of which you can see on a separate page foundry for gasified models. During the production of hinged segment mowers, KSF 2.1 PPOs was monitored in the fields in order to track and then fix or completely upgrade the weaknesses of the frame or cutting apparatus. KSF 2.1 is mainly used in small farms and private farmsteads as the most economically profitable type of agricultural machinery for cleaning small agricultural land, as it can be aggravated with small tractors from T-25 to MTZ-82. Segment.palting cutting devices are used in cleaning agricultural cultures for many decades, on various types of harvesting agricultural machinery. Such devices have established themselves from the most unpretentious and best side. If we talk about hinged and not trailed or self.propelled mowers, then in larger farms, state farms or collective farms a more powerful mower with a rotary cutting apparatus KRN 2 is used.1 or KDN 2.one. Such braids have rotary rotating drums with flat or curved knives. Rotor KRN or CDN mowals have a high rotor rotation frequency, respectively, higher performance. Rotary hinged mowers require more financial costs for its operation.

Basic rules of hayfields important factors of hay harvesting hay is one of the most important factors in the diet of livestock to provide a diet during winter. If you remove hay in the early phases of vegetation, it will turn out to be the highest quality. It is during this period that in young, facial herbs, the maximum amount of nutrients is contained. Unlike stems in the foliage, there are 10 times more vitamins and 2.5 times more digestible protein. Like everything in our nature, plants have the ability to age and in the process of aging in them there are fewer nutrients. Feed plants grow quite quickly and therefore the harvesting of herbs on hay should start in the optimal time and will legitate the haying for 10 days. If you start cleaning with a delay in optimal terms, then you can much less collect nutrients in plants and naturally reduces their digestibility. If the weather allows early cleaning of herbs, then you can eventually get the second and sometimes the third mowing of the grass. Hayfields can be produced not only in hot and dry weather, grass mowing can be produced even after rain, but only after good wind. If you mow the grass after the rain and not let it go well before the mowing, then naturally such a grass will dry much longer as it will be in the prochos, and as a result, with a longer drying, it will lose much more nutrients. If green high mass prevails in the harvest, then it is better to make with mowers segmented CS: GO-2.1, KDP-4, or rotary hayfields such as KRN 2.1 or KDN 2.one. After the injection of the grass, it must be rejoiced. For turning grass masses in crooks, wrapping and scattering rolls, we recommend using rakes such as GVK-6. After the injection of the grass, it must be turned right away as it will blow out and dry faster. The mowed mass of grass must be turned over especially on an uneven dense layer of mowed grass. After drying the upper layers, it is necessary to carry out repeated turning and so on until the humidity is-22%. If the herbs are mowed into the roll, then turning at least three times to ventilate the thick layer. After pricing and drying the hay, it is collected with the help of a collection press p. 145, Kyrgyzstan and so on which collect hay in pressed bales and wrapped them with a twine. When harvesting hay, the dry the better, since if the pressed hay has a humidity of more than 25%, then the hay can mold from the inside due to self.heating. After cleaning, if the weather is favorable on the street, bales are left in the field for driving for 3 days, putting them in a pyramid. After all these procedures, hay can be filed for storage.

Adjusting mowing mechanisms

Before starting the mower, it is necessary to carefully check the correct assembly, adjust the mechanisms, hand them out manually.

Регулировка положения ножа в режущем аппарате.

Before the work of the mowing, check the reliability of the mount and the location of the fingers on the beam. It is very important that the contradictory plate of the fingers be located in one plane. Their position is checked using one or two cords stretched over the vertices or the bases of the proto-cutting plates. All contradicting plates should touch the stretched cords. Curved fingers are straightened with a special key or light hammer blows.

For reliable cutting of the stems, segments must fit the contradictory plates in the front, and have a gap of 0.3 at the rear base.0.5 mm. This is achieved by bending of the knife jackets and the extension of the friction plates. In this case, the gap between the knife press and the segment, as well as between the knife back and the friction plate should be within 0.3. 0.5 mm. With the indicated gaps, the knife stroke should be light, and the knife head should not have a “game” in the guides.

In the extreme “dead” positions of the knife, the axial lines of segments and fingers must match. This adjustment (knife centering) is carried out by a change in the length of the connecting rod. If the device is not discounted, then due to a decrease in the speed of the knife in the cutting zone, segments do not cut part of the stems and tighten them into the intervals between segments and fingers. Deviation of the axial lines of segments from axial fingers within 3 is allowed. 5 mm Depending on the design of the braid, in high-speed braids CS: GO-2.1, the distance between the axes of segments and fingers is 76.2 mm, and the knife stroke is reduced to 68 mm in order to reduce the forces of inertia during its operation. Therefore, in the extreme right position of the foot of the middle of the segments should not reach the middle of the fingers by 5 mm.

Регулировка наклона режущего аппарата.

When mowing plants on the uneven surface of the soil, in order to avoid burrowing fingers into the ground, the cutting apparatus is tilted back. With a lightweight, the grass.resistant cutting apparatus is tilted forward so that the fingers do not wet the grass, but raise it. The slope of the cutting apparatus is carried out by turning the hinge relative to the traction rod.

Cut height within 5. 7 cm is installed by rearrangement of the skills of internal and external shoes. When adjusting, agricultural requirements for the height of the soil are taken into account.

Регулировка положения режущего аппарата относительно шатуна и трактора.

For the normal operation of the braid, it is necessary that the cutting device is located parallel to the axis of the rear wheels of the tractor. In this case, the knife and connecting rod work in one vertical plane. However, under the pressure of the cut grass and in the presence of gaps in articulated joints, the cutting device moves back. Therefore, before the work of the mower, the outer end of the finger beam is taken forward by 35. 55 mm relative to the internal (run of the cutting apparatus). The necessary race is set by turning an eccentric sleeve with a simultaneous change in the length of the sprenigel. At the mowing tractor, the race is checked relative to the straight line drawn in parallel to the axis of the rear wheels of the tractor, through the nose of the finger located next to the inner shoe.

When developing holes in the ears of a hinge and inner shoe or with wear of the pins connecting the hinge and shoe, the outer end of the cutting apparatus moves back. Return the device to its original position by turning the eccentric sleeve to the left.

The tension of the drive of the drive mechanism is regulated by the movement of the drive pulley using a stretch screw.

При подъеме аппарата навеской трактора внутренний башмак должен от­рываться от земли примерно на 100—150 мм раньше, чем наружный. Этого добиваются регулировкой стяжного звена механизма подъема. Перед регулировкой необходимо ослабить натяжение компенсационной пружины.

Высота подъема и устойчивость движения режущего аппарата по почве зависит от того, через какое отверстие соединительной планки будет соединен передний рычаг подъема. При работе с тракторами Т-25 передний рычаг должен быть прикреплен к нижнему отверстию планки. При работе с тракторами МТЗ — к среднему, а при работе с остальны­ми тракторами — к верхнему отверстию.

Для надежного разделения срезанной и несрезанной травы и очистки дорожки для про­хода внутреннего башмака режущего аппарата при после­дующих заездах необходимо в зависимости от высоты к перепутанности травостоя производить отгибку двух верх­них прутьев полевой доски.

При переоборудовании косилки для скашивания бобовых культур снимают режущий аппарат с косилки и на его место устанавливают режущий аппарат приспособления вместе с валкообразующей решеткой. На каждый третий палец крепят стеблеподъемник. Угол между поверхностью почвы и верхней гранью стеблеподъемника устанавливают в пределах 15—16°.

Эксплуатация, обслуживание и ремонт

Как и любая сельскохозяйственная техника, устанавливаемая на Т 25, МТЗ и мотоблоки, сегментные косилки изнашиваются и периодически ломаются.

Чтобы это случалось как можно реже, следует соблюдать такие правила пользования изделием:

• Крепление проводить с фиксацией продольных тяг навески тягача, чтобы исключить боковое смещение рамы косилки.
• При работе на неровной местности выставлять высоту, которая бы исключала возможность втыкания режущей части в грунт при наклоне тяглового устройства.
• Если есть такая возможность, следует проверять незнакомую местность на предмет наличия камней, арматуры и строительного мусора. От контакта с этими предметами косилки ломаются.
• Скорость скашивания следует выбирать исходя из плотности и состава растительного покрова. По мягкой траве агрегат можно вести со скоростью 5 км/ч. Целину или поле обрабатывать следует не быстрее 2 км/ч. В этом случае можно рассчитывать на качественный результат.
• После каждого скошенного гектара необходимо тщательно очищать инструмент от набившейся в него травы, земли и прочего мусора. Можно прочистить резаки сжатым воздухом. После очистки косилка обрабатывается смазкой.
• При поломке навесного оборудования ремонт можно проводить только после остановки тягача и отключения от него косилки.

Во время работы следует каждые 1,5-2 часа проверять натяжение ремня и затяжку крепежных гаек.

Принцип работы косилки навесной сегментной

Косилка сегментная навесная оснащена ножами для среза растений, которые передвигаются возвратно-поступательным способом, благодаря валу транспортировочной техники. Движение осуществляется в параллельном соотношении с земляной поверхностью, повторяя ландшафтный рельеф.

Данная особенность дает возможность косить растительность небольших размеров. Благодаря специальной закалке и особому способу заточки, режущие элементы сегментно-навесного устройства обеспечивают эффективный и длительный период эксплуатации.

Косилка сегментная навесная — оптимальный выбор для тех случаев, когда необходимо производить скос растительности на буграх и склонам, а также в равнинной местности. Если сравнивать с роторными механизмами, то косилка сегментная навесная немного сложнее в эксплуатации и обслуживании.

Особенности косилки CS: GO-Ф-2.1

Она работает на ровных и чистых территориях. Недопустимо попадание в механизм камней и прочего твердого мусора, которые приводят к поломке режущих сегментов.

Такие косилки имеют много положительных качеств:

• высокая производительность, большая ширина обрабатываемой полосы;
• возможность работы на компактных тракторах ввиду малого веса установки;
• небольшие энергозатраты, позволяющие сохранить себестоимость продукции на прежнем уровне при малых объемах заготовок;
• простота управления. Для нее достаточно одного тракториста, без дополнительных помощников;
• высокое качество производимых работ по укосу трав и длительный срок службы. По окончании сезона полевых работ на устройстве необходимо просто заменить режущее полотно.

Для них наиболее подходят тракторы ЮМЗ, МТЗ 80 и МТЗ 82, более компактные тракторы Т 25 и Т 40.

Эта марка косилок успешно работает на огромных полях колхозов и у фермеров. Высокий спрос обусловлен многообразием модификаций, среди которых:

• беспальцевая;
• со срезом под названием «Шумахер», немецкого производства;
• с наличием гидроцилиндра в подъемном механизме;
• другие варианты исполнения.

Наиболее востребованной из них является разновидность модели Б4, отличающаяся более надежной рамой, брусом режущего инструмента, повышенной надежностью предохранительного устройства. На ней проще производить необходимый наклон режущего полотна.

Подобная ей модель класса В – более легкая, отличается наличием механизированного подъема с помощью гидроцилиндра, но трактор ей нужен более мощный.
