o
PTO shaft end extension 1 (6 splines) under ISO 500
o
PTO shaft end extension 2 (21 splines) under ISO 500
The front PTO is continuous, single-speed with a PTO shaft end extension of type 2
(21 teeth). The direction of rotation is clockwise when viewed from the shaft end face.
The transmission hydraulic system provides for the following:
o
engagement of gearbox friction clutches, PTO and FDA drives, differential lock;
o
filtration of transmission oil;
o
pressure feed lubrication of gearbox bearings, pump drives for HLL and trans-
mission HS, PTO and RA.
Steering is hydrostatic. The feed pump is gear-type, the direction of rotation is left.
The dosing pump of forward motion is gerotor-type, two-box. The dosing pump of the re-
verse motion is gerotor-type, one-box. The type of the rotation mechanism: two hydraulic
cylinders of bidirectional operation and a steering linkage.
The
forward driving axle is a coaxial type, with planetary final gears. The main drive
is a pair of bevel gears with circular tooth. The differential is self-locked, with increased
friction. The FDA drive is a reduction unit, built in the rear axle, with a multidisk, frictional
hydraulically-operated clutch and the crankshaft. The FDA control is electro-hydraulic.
The hydraulic lift linkage is universal, with joystick control, based on axial-plunger
adjustable pump of «Bosch-Rexroth» company, providing for the draft, position and com-
bined adjustment of tillage depth, having a four-section distributor with electrohydraulic
control and a possibility of programming the hydraulic system functions (EHS), electrohy-
draulic adjustor to control front and rear lift linkages. The hydraulic system has four pairs of
independent outlets with one pair leading to the front lift linkage with a possibility to adjust
the working liquid feed at each outlet.
The
pump of the hydraulic system has a variable productivity, driven from the en-
gine through a gear of PTO continuous drive.
Free drain is available in front of the tractor as well as behind it.
The rear lift linkage is a four-bar linkage of category 3 under ISO 730. There are two
cylinders Ts110x250.
The front lift linkage is a three-point linkage of category 2 under ISO. There are two
cylinders Ts90x250
Drawbar hitches of a lift type:
- towing yoke for coupling with semi-trailers and semi-trailed implements.
- towing bar for coupling with towed implements.
The cabin is a one-seated with a protective rigid framework, having thermal, noise
and vibration insulation, with a system of heating, air-conditioning and ventilation,
equipped with a sprung seat adjustable for operator's height and weight, with rear-view
mirrors, with a sun visor, with electrical wipers for front and rear screens, with front and
rear screen washers, with a roof lamp and a place to install a radio set. The cab doors
have got locks, there are keys for the left door. The right door is for emergency exit. The
cab complies with category 2 under EN 15695-1:2009.
The rated power supply voltage for on-board network is 12V and the rated voltage
for the start-up is 12V.
