10
The mower (Fig. 1.4) is a hinged apparatus without worksite, it’s controlled and maintained by
operator (tractor operator).
Cutter bar 1 is a working element of mower, which is connected to bevel gear speed reducer
by threaded coupling.
Bevel gear speed reducer is fixed in plain bearing 19.
Two floated cutting blades attached to each rotor mounted on mower cutter bar.
Five rotational rotors mounted on mower ZTT-2,1, ZTT-2.4 has six rotors and mower ZTT-2,8
has seven opposite run rotors.
Three point hinge 13 is a main mower member with bracket 11 hinge mounted to swing mount
apparently to which the mower can run in horizontal plane when safety lock 18 is operating.
Bottom of swing mount is a hinge, allowing mower to rotate vertically during mower transfer
from transport position to on position and reverse one.
Small bar 16 is attached to swing mount bottom.
Four pins attach two plain bearings opposite bar end, where bevel gear speed reducer is
floated.
Except cutter bar tent frame 2 is fixed to the reducer, where tent 10 is mounted with use of
clamps.
Tent 10 and tent frame 2 provides access guarding to cutter bar, overlapping cut trajectory
more than 3 mm and they designed to prevent foreign objects coming out of working area as
well.
Tractional safety lock 18 is located under small bar.
Gear 14 with driving (big) pulley is attached to small bar on the bracket.
To protect V-belt drive the apparatus is furnished with protective removable housing 12,
attaching with use of captive bolts.
Cylinder actuator 8 serves for raising and lowering of small bar with all mounted assemblies on
it.
Connection of apparatus to tractor is carried out with use of hinge 13 and power transmission
–through telescopic cardan shaft with free-wheel clutch 20 guarded by protective housing 22.
When removing mower from tractor, the cardan shaft 20 is set to the sling (Fig. 1.11).
To prevent mower turnover when at idle (parking) state and transportation provision of stand
15 was made.
When operating mower, stand 15 should be fixed in uppermost position.
1.4.2. Operation of mower
Tractor draft force is used for mower operation.
Actuation of driven elements is performed from tractor power-takeoff shaft (PTO) through
telescopic cardan shaft.
Cutting of plants’ stems is carried out with use of segmented blades pivotally mounted on
rotors speeding with 65 m/s towards one another.

11
Blades cut herb on the principle of unsupported shear, pick up it and take out it from area of
shear, moving over cutting bar.
When striking the panel of outside divider the mowing herb is changing motion path, packing
into the swath and standing down for tractor wheels run during successive pass.
Swath width is set by swath former vanes motion.
1.5. Components description
1.5.1. Drive
Mower drive (Fig. 1.5) consists of bearing case 4, where bearings 2 are to be inserted.
Bearings are fixed with locking rings 3.
Shaft 1 is rotating in bearings, where three grooved pulley 5 is mounted.
Shaft torque is passing to pulley by tab to driven pulley 8 with help of belts 7.
Don’t allow excess or lowering of assigned limits in section 4.2.3.
Driving and driven pulley grooves should be in the same plane.
It’s achieved by relocation of shims from one side of bearing case to other one.
In this case difference between pulley groove planes should be 2 mm, max.
Рис. 1.5. Mower drive
1.5.2. Tractional safety lock
Tractional safety lock (Fig. 1.6) prevents cutter bar and reducer elements from damage during
collision of the bar with obstruction (invisible in grass stubs, stones, etc.).
Safety lock is connected with small bar by fork 6 and with hinge frame by hinged bearing 3.
Operation of safety lock is as follows:
When operating normally, link rod 4 and guide rod 2 are fixed with sheared element (pin) 5
from longitudinal motion and due to it the mower controls remain in normal (operating)
position. When hitting an obstruction, pin 5 becomes sheared permitting link rod 4 to move
freely along the guide rod 2 to stop 1.

12
In this case mower controls are steering relatively swing mount 12 (Fig. 1) backward along the
tractor movement, thus taking away cutter bar with reducer from obstruction, minimizing
possibility of cutter bar and reducer elements damage.
Tractional safety lock should activate under force of 3000 N (300 kg) applied to center part of
cutter bar.
To continue operation it’s required to raise mower on rear tractor hinge device that cutter bar
could drive off the ground and after that manually align holes of rod 2 and rod 4 and insert
new cut element (bolt).
Fig. 1.6. Tractional safety lock
1.5.3. Cutter bar with gear
Cutter bar (Fig. 1.7) is the main mower working element.
Rotors 2 installed on cutter bar, where fitted two cutting blades 3.
Five rotors mounted in mower model ZTT-2,1, six rotors mounted in model ZTT-2.4 and seven
opposite running rotors mounted in model ZTT-2,8.
Torque of tractor power take-off through cardan shaft with clutch, drive and V-belt drive is
transmitted to bevel gear speed reducer 4 and from there through train of gears to rotor
shafts.
Rotor blades attached floating and are self-centered into operating position when rotors are
running during mower operation under centrifugal effect.

13
Fig. 1.7. Mower cutter bar
It’s required to observe constantly for condition of mow out blades and
grease in reducer 4 and cutter bar. Missing of grease can cause bar and
reducer overheating and their malfunction.
1.5.4. Cutter bar balance unit
Balance unit (Fig. 1.8) is intended for provision of even pressure to the soil produced by cutter
bar over the whole area of panel bottom and profiling the roughness of soil relief as well.
Adjustment is carried out by tension screw of springs 7 (Fig. 1.4).
Pressure of external boot onto the soil should be within 200 to 300 N (20 to 30 kg), that
should be adjusted by springs 1, pressure of internal boot should be within 700 to 900 N (70
to 90 kg), that should be adjusted by spring 2 (Fig. 1.7).
Fig. 1.8. Balance unit
1.5.5. Functional diagram
Functional diagram of mower ZTT-2,1 is given in Fig. 1. 9.
Torque is transmitted from tractor rear power take-off shaft (PTO) through cardan shaft with
free wheel clutch to mower power reception shaft (PRC).
Then PRC transmit torque to cutter bar with reducer with help of V-belt drive.

1.5.6. Hydraulic system
Mower hydraulic system (Fig. 1.12) is made as a single-line one and consists of a cylinder
actuator Awith throttle B, high pressure sleeve Dwith joint quick disconnect clutch C.
Cylinder actuator Ais intended to put mower into stowage or operating position.
Non-adjustable throttle Bserves for setting of optimum speed of cutter bar lowering and
raising.
High pressure sleeve Dis designed to supply operating fluid to cylinder actuator A.
Quick disconnect clutch Cis designed to perform connection with tractor and preventing
operating fluid leaking during disconnection from tractor hydraulic system.
When disconnecting high pressure sleeve Dof mower hydraulic system from tractor hydraulic
system, it’s required to put special plug on quick disconnect clutch (Fig. 1.13).
Optimum high pressure sleeve Darrangement ensures missing of folds, bends and chaffing. E
is a direction of operating fluid running.
