3 Pro uct esign an operation
3.1 Device components
The mower is a hinged machine without the operator's workplace, It is operated and
maintained by the machine operator (tractor operator).
The main components of the mower are cutting device 5 (Figure 1.1, figure 1.2), hinge 9
and connecting small beam 2.
Oppositely rotating rotors from the drive gearbox rotors of the cutting device carry hinged
fixed cutting knives - two or three each (only for ZTT-3.2 "Strige Y"). Depending on the model
of the mower, the number of rotors varies - 7 (ZTT-2,8) or 8 (ZTT-3,2). The field divider of the
cutting device (or disk swaths) is designed to form a roll of a sloping mass; Awning 4, fixed to
the frame of the tent 6, prevents spreading of the sloping mass.
The small beam is articulated with the reduction gear of the cutting device and the linkage
which allows the cutting device to copy the field relief. The force of contact between the cutting
device and the soil is regulated by changing the tension of the springs of the counterbalancing
mechanism 7 between the small beam and the weighed portion. A drive 16 with a leading
(large) pulley is attached to the small beam from below on the bracket. Under the small beam
there is a traction fuse 1 connected to the hitch.
To connect a small beam, a double hinge is mounted on the hinge, which allows the cutting
device to rotate vertically from the operating position to the transport position, and vice versa
and to bend back in the horizontal plane when the mower hits the obstacle and traction fuse
activation.
The connection between the machine and the tractor is carried out by means of a linkage and
the transfer of power from the tractor PTO to the reduction gear of the cutting device via the
telescopic drive shaft with the overrunning clutch 11, drive 16 and V-belt drive 15. The tension
adjustment of the V-belt drive is performed by the tensioner 18. To protect the V-belt drive a
casing 14 is installed. Hydraulic cylinder 13 is served to lift and lower the cutting device and a
small bar with all the assembled units on it.
The width of the roll is adjusted using the field divider 20 (Figure 1.1) or swath former 20
(Figure 1.2).
3.2 Design an operation of the mower an its main parts
The tractive power of the tractor is used to operate the mower. Cutting rods of plants is carried
out with the help of plate-shaped knives, hingedly mounted on the rotors of the cutting device,
rotating at a peripheral speed of 65 m / s towards each other. The knives cut the grass
according to the principle of unsupported cut, pick it up and carry it out of the cutting area,
moving it beyond the cutting device. The trajectories of the motion of the knives of neighboring

9
rotors overlap mutually, thus a qualitative swath is ensured.
3.2.1 Drive
The drive consists of the bearing housing 4 (Figure 3.1) in which the bearings are installed 2.
The bearings are secured with locking rings 3. The shaft 1 rotates in the bearings on which the
driving pulley 6 is fixed by the nut 7. The torque from the shaft to the pulley is transmitted by
key 5. The tension of the belts is adjusted by changing the compression force of the spring 4
(Figure 3.2) with the nuts 6 on the tension screw 1. Their deflection should be about 15 mm in
the correctly adjusted transmission with an effort applied in the middle of the branch to each
belt, Q = 70 H (7 kg) (Figure 3.2).
CAUTION: too much belt tension can amage the belts an rive!
Insufficient tension can cause slippage of the belts on the pulleys, which lea s to
poor quality mowing an reeling the grass on the rotors of the cutting evice!
The grooves of the driving and driven pulleys must be in the same plane. This is achieved by
shifting the shims from one side of the bearing housing to the other. In this case, the difference
between the planes of the grooves of the pulleys should not exceed 2 mm.

3.2.2 Traction fuse
Traction fuse is designed to prevent damage to the elements of the cutting device and
gearbox when it collides with an obstacle (invisible in the grass stumps, stones, etc.).
The main elements of the traction fuse are shown in Figure 3.3. Using a plug 6, the fuse is
connected to a small bar, the hinged support 3 - to the frame of the sample.
Operation of the fuse is as follows. During normal operation of the mower, the thrust 4 and
the guide 2 are fixed by the shear element (bolt) 5 from the longitudinal movement, thus, the
cutter's mower is in its normal (working) position.
When the obstacle is hit, the bolt 5 is cut, allowing the pull rod 4 to move freely along the
guide 2 to the stop 1. At this, the cutting device of the mower rotates backwards along the
tractor's axis 9 (Figure 1.1) as the tractor moves, from the obstacle, reducing the likelihood of
damage to the elements of the cutting device and gearbox.
The traction fuse should operate at an effort of 3000 N (300 kg) applied in the middle of the
cutting device. To continue the work, it is necessary to feed the tractor back, to align the holes

11
of the guide 2 and the link 4, and insert a new shear element (bolt).

3.2.3 Cut evice
Cut device is the main unit of the mower. Constituent units are shown in Figure 3.4.
Cut device includes seven (ZTT-2,8) or eight (ZTT-3,2), rotors 2, on each of which, two
mowing knives 3 are hinged (for ZTT-3,2 "Strige Y" 3 knives).
The torque from the tractor's power take-off shaft through the propshaft with the
overrunning clutch, the drive and the V-belt drive are transmitted to the bevel gear 4, and from
it through the gear system to the shafts of the rotors. Knives on the rotors are fixed articulated
and when the rotors rotate during operation, the mowers, under the action of centrifugal
forces, are self-aligned into the working position.
ATTENTION: It is necessary to constantly monitor the con ition of the mowing
bla es an the presence of lubricant in the re uction gear an crankcase of the
cutting evice. The absence of lubricant can lea to overheating of the cutting
evice an gearbox an their failure!

3.2.4 Hy raulic circuit
The hydraulic circuit of the mower is a single-line and consists of a hydraulic cylinder, and
high pressure hoses designed to transfer the mower from the transport position to the working
position and back. To prevent the mower from tipping over, a constant-section choke is built
into the hydraulic system of the mower, which allows the mower cutter to be lowered or raised
slowly, without jerking at low speed.
3.2.5 Balancing mechanism
The balancing mechanism is designed to provide uniform pressure on the soil of the bearing
surface of the cut device, and also to copy the unevenness of the soil relief.
The adjustment is made by the tension screws of the springs of the mechanism 7 (figure 1.1,
1.2).
The pressure of the outer shoe on the soil should be in the range from 200 to 300 N (from
20 to 30 kg), pressure of the inner shoe is from 700 to 900 N (from 70 to 90 kg). Pressure
measurements shall be carried out using a dynamometer DPU-01-2-VI GOST 13837-79.
