Page 1

The classification of mowers is as follows. Mowers are divided according to the number of cutting devices and purpose.

According to the number of cutting devices, mowers are single-bar, double-bar, triple-bar and five-bar.

According to their purpose, mowers are divided into grass mowers, mower-conditioners and chopper mowers.

The agrotechnical requirements are as follows. Mowers must ensure that feed is obtained without loss and of high quality. They must: cut natural grasses no higher than 6 cm and seeded grasses no higher than 8 cm, lay the mown mass in straight windrows, turn the windrows half a turn to dry the lower layers, create conditions for the complete collection of the mown mass of standard moisture.

Types of mowers:

The mounted rotary mower KRN-2.1A is used for mowing high-yielding natural and seeded grasses. The mower is combined with tractors MTZ-80 and MTZ-82.

The mower includes a hitch frame 8, a rotary cutting device 3, a balancing mechanism 4, a subframe 5, hydraulic equipment 7, a traction fuse 9, a drive mechanism 10 and a field divider 1.

The workflow is as follows. Plant stems are cut with blade knives hinged on rotors. The knives rotate towards each other at a speed of 65 m/s. Plant knives are cut according to the principle of an unsupported cut, they are grabbed and taken out of the cutting zone, then moved over the cutting apparatus. This cut mass, meeting the field divider shield, changes the trajectory of movement, falls into the swath, freeing up space for the tractor wheels to pass during the second drive.

The hitch frame provides connection of the mower to the tractor hitch. It consists of a main frame and suspension.

The main frame is welded and has axles for connecting it to the lower links of the tractor hitch. The right side of this frame is equipped with an axle for the traction fuse. After installation, this fuse is fixed to the axis with a pin and a cotter pin. The suspension is hinged to the frame, the lower part of which is equipped with a bracket for installing a subframe. The suspension has a chain for connecting the transport rod. A rotary cutter is used to cut grass. The device has a timber panel and a bottom, fastened with bolts. Shoes are placed under the bottom for support on the ground.

The cutting device rotates in the axles of the brackets, which allows you to follow uneven soil. The cutting device is equipped with four identical rotors. Each rotor is equipped with two knives, which are hingedly mounted on special bolts. The middle rotors are equipped with elongated blades.

The right side of the cutting device is equipped with a bracket for attaching a field divider. The balancing mechanism ensures: limiting the pressure of the cutting device on the soil, copying field unevenness with this device, and moving the mower to the transport position.

The balancing mechanism includes a hydraulic cylinder articulated with a lever. This lever is connected to the cutting device using a freewheel.

In the transport position, the balancing mechanism is fixed with a transport rod thrown onto the bracket pin 2 (Fig. 1) and a telescopic locking device installed in the transport position. Hydraulic equipment ensures the operation of the balancing mechanism.

The hydraulic equipment includes: a hydraulic cylinder, a delayed valve, a breather, high-pressure hoses and a device that prevents oil from leaking out of the hydraulic system when it is separated from the tractor.

The traction fuse serves to protect against damage to the cutting device when encountering an obstacle. It has two rods with wedge clamps. In the fixed state, the latches are held using the force provided by a cylindrical spring. The force for triggering the fuse is adjusted with a nut.

The field divider separates the mown mass from the unmown grass. The field divider includes a bracket, a divider shield, a spring with a cup-washer and a bolt. The divider shield is mounted so that it forms an angle with the direction of movement of the unit. In the working position, this shield is held by a spring, which allows it to move back during overloads and return to its original position when overloading them.

The KPRN-ZA rotary mower-conditioner is used for mowing high-yielding seeded grasses with simultaneous flattening of the stems and laying the mass in a windrow or spread. The machine can work in fields with tangled and laid down grass in conjunction with MTZ-80, MTZ-82, YuMZ-6AL tractors. Drive of the mower's working parts from the tractor's PTO.

The mower consists of a frame assembly, a driveshaft with a cardan drive, a cutting device, conditioning rollers, a transmission and a protective device. The grass is mowed using a rotary cutting device. The rotors, having counter rotation and having a high peripheral speed of rotation of the knives, carry out unsupported cutting of plants. Knives and rotor discs feed the cut grass into the area of ​​the flattening rollers. Further flattening of the plant mass is carried out by ribbed flattening rollers across the entire working width. Then this mass is placed into the windrow by the guides of the swath-forming device. It is not recommended to flatten grass in wet weather, because... Flattened stems rot faster than unflattened stems.

During operation of the mower, the blade with knives is driven in a reciprocating motion parallel to the surface of the ground. In this case, the stems that get in the way fall onto the stationary segments of the canvas and are immediately pressed tightly against them, moving the blades. Cutting the grass is similar to the work of regular scissors, leaving a strip of finished mowing. Scheme of the KSF-2.1 mower 1. Cutter head; 2. Guide knife heads; 3. Knife head cover; 4.

Operation of the T-25 tractor with a mounted mower

The KZN-2.1 mower (Fig. 29) is mounted on the rear suspension device of the T-25 tractor

Rice. 29. Mounted mower KZN-2.1.

The drive of the working parts of the suspended mower is carried out from the power take-off shaft of the T-25 tractor. Before hanging the mower, you need to prepare the tractor, which consists of the following: 1. Rebuild the T-25 tractor to the highest setting; 2. The track of the front and rear wheels is set within 1400-1500 mm; if this requirement is not met, the wheels will crush the mown grass and it will be difficult to control the tractor; 3. Adjust the central rod of the suspension device so that its length is 590 mm; 4. Adjust the braces so that their length is 490 mm; 5. Move the longitudinal rods to the middle holes of the brackets; 6. Raise the rear suspension and , by moving the lifting arms on the splines of the lift shaft, set the suspension axis at a height of 600 mm. Hanging the mower is done in the usual manner, described in the general instructions for hanging and working with mounted machines. After hanging, lift the mower so that the cutting device does not touch the ground, and by adjusting the length of the braces, level the mower in the transverse plane (the mower frame should be placed horizontally). By adjusting the locking devices, remove the lateral displacement of the mower frame relative to the longitudinal axis of the T-25 tractor. Lower the mower until its legs touch the ground, which corresponds to the location of the mower's suspension axes at a height of 350 mm from the ground. During operation of the mower, its suspension axles should not fall below 350 mm, which is achieved by installing the limiting clamp on the cylinder rod in the appropriate position. When moving, you need to raise the mower to the transport position, loosen the bolt securing the front stand, set it in a horizontal position and tighten the bolt tightly. Remove the lower bolts securing the rear strut to the frame and loosen the upper ones, set the strut in a horizontal position and secure firmly with the previously removed and loosened bolts.

We mow the grass with a segment mower KS-2.1

In this video I talk about modifying the mower

Modernization of the KSF-2.1 mower. Pulley replacement

First, a video of a piece of haymaking in 2020. Before replacing the drive pulley, our mowing proceeded approximately like this.

Before operating the mower, you need to carefully check the correctness of assembly, adjust the mechanisms and turn them manually using the eccentric.
cutting device blade parts must lie on the finger pads.
If there are gaps between the liners and the ends of the parts or between the clamps and sectors, then during operation the cutting apparatus will become clogged with weed, and great effort will be required to cut, which can lead to the knife breaking. Operation mower on various types of land

If the ground is uneven, the cutter may dig into the ground. To avoid this, tilt the cutting unit backwards. When the grass is laid down, the cutting device must be tilted forward so that the fingers do not crush the grass, but, going deeper into the laid down mass, lift it. When working on lumpy or rocky soil, in order to avoid breaking the fingers of the cutting device and parts of the knife, it is necessary to increase the height of the finger bar relative to the ground. To do this, it is necessary to move the soles of the inner and outer shoes to the overlying holes, as a result of which the height of the grass cut will increase. When moving the soles to the underlying hole, the cutting height of the grass will decrease. To reduce damage to plants when moving the mower, and to reduce clogging, the cutting device should put as little pressure on the ground as possible. To reduce this pressure, you need to increase the tension of the lift spring, but so that when the mower is operating, the cutting device does not jump and does not come off the ground, but adapts to the unevenness of the ground. When operating the mower on sandy soils or flooded meadows, where there is sediment of silt and sand, the blade clamps should not be lubricated, because the sand, mixing with oil, will linger on the parts and, getting between the rubbing parts of these parts, will increase their wear. The mower's cutting device must operate across the entire working width. To do this, you need to drive the tractor so that the inner boot goes as close as possible to the edge of the unmown grass. To avoid running into an obstacle with the cutting device, it must be lifted using the attachment of the T-25 tractor. To avoid accidents when working with the mower, you must follow the following rules: 1. Before starting the mower , make sure that no one is in front of the machine; 2. When stopping the unit, be sure to turn off the tractor power take-off shaft; 3. Make corrections to the mower when the tractor engine is not running; 4. When cleaning the cutting apparatus from grass at stops, do not touch the cutting parts with your hands; 5. When installing the mower into the transport position, do not touch the fingers of the cutting device .
