Introduction
The present manual is designed for studying the structure, operation rules and
maintenance of tractors “BELARUS-2122.6”.
Scrutinize this manual. It will help you to study the rules of correct operation and
maintenance.
Failure to follow these instructions can lead to operator's injury or a tractor break-
down. Tractor operation, its maintenance and repair shall be carried out only by employ-
ees, familiar with all of its parameters and characteristics and informed about necessary
safety requirements to prevent casualties.
Due to constant tractor development, some changes which are not specified in the
present manual can be introduced in the structure of certain units and parts.
Any arbitrary changes made by a consumer release the manufacturer from respon-
sibility for possible further injuries to the operator and a tractor breakdown.

1. TRACTOR DESCRIPTION AND OPERATION
1.1 Tractor assignment
Tractor “BELARUS-2122.6” is intended for performance of power-consuming agricul-
tural operations in traction and traction-driven modes coupled with wide-span and multi-
purpose units, including separated link implements: for basic and pre-sowing tillage, cereal
and other crop sowing, forage conservation, root crop, grain crop and industrial crop harvest-
ing; for transportation and stationary operations; for municipal service, construction, industrial
operations.
Tractor “BELARUS-2122.6” is a general-purpose wheeled tractor of traction class 4 with
the wheel arrangement 4X4.

1.3 Tractor composition
Tractor framework is semi-frame.
Undercarriage – front and rear wheels are driving, with pneumatic tires of low pres-
sure. Front wheels are steering. Rear wheels can be twinned by means of a spacer.
The tractor is equipped with a 4-stroke piston six-cylinder inner combustion engine
with in-line vertical arrangement of cylinders, with direct injection of diesel fuel and com-
pression ignition, corresponding to environmental requirements of Stage 4.
The system of engine lubrication is combined, some parts are lubricated under pres-
sure, some – by spattering. The lubrication system consists of an oil sump, oil pump, liq-
uid-oil heat exchanger, centrifugal oil filter and oil filter with paper filtering element.
The engine fuel supply system consists of the following parts:
- accumulator system of fuel supply Common RAIL, including a high-pressure fuel
pump, injectors, a fuel accumulator under high pressure, sensors of the engine working
environment condition (pressure and temperature of fuel and air), electromagnetic actuat-
ing mechanisms (fuel governor, electromagnetic injection valves), electronic unit of control
and communication check circuits, low-pressure pipelines, high-pressure pipelines;
- fuel fine filters;
- fuel coarse filters.
The system of engine start-up is an electric starter. A means of start-up facilitation
under low environmental temperatures are heating plugs.
The system of air delivery consists of a turbocharger, an air pipeline and a system of
inlet air cooling.
The turbocharger is executed as follows: a radial centripetal turbine and a centrifugal
single-stage compressor with a cantilever arrangement of wheels in relation to supports.
The system of air purification consists of a dry-type air cleaner with a built-in unit
“monocyclone” and two paper filtering elements. Air ingress with an air-cleaner is per-
formed through the “monocyclone” unit which provides preliminary inertial air cleaning at
the expense of tangential inflow and centrifugal forces, arising at spiral air rotation in rela-
tion to the axis of many small separate slots of “monocyclone” unit, discharging large-size
dust particles.
The cooling system for inlet air is of a radiator type. The CAC radiator is intended for
cooling the air, charged into the inlet collector.
The cooling system is closed-type with coolant compulsory circulation carried out by
a centrifugal pump. The water pump is driven by a V-belt from the crankshaft pulley. Two
thermostats TC-107 mounted at the delivery line are provided for acceleration of engine
warming-up after start-up and for automatic control of a temperature mode at various load-
ings and ambient temperatures.
To provide the required chemical composition of exhaust fumes, corresponding to
ecological requirements of Stage 4, the exhaust fumes system is additionally equipped
with two stages of selective catalytic reduction (SCR1, SCR2).
The coupling clutch is frictional, dry, two-disk, spring-loaded. The clutch pads are ce-
ramic-metal. The coupling control drive is hydrostatic with a hydraulic booster.
The gearbox is 16х8 hydromechanical, step-by-step, with constant-mesh gears, shift-
ing of gears within the ranges is carried out by means of hydraulically-operated friction
clutches; switching between ranges is carried out by toothed clutches and a synchronizer.
Shifting of GB reduction unit ranges is electrohydraulic.

Rear axle:
- with the main drive – a pair of bevel pinions with circular teeth;
- with the hub drive – a pair of cylindrical gears;
- with final drives – of planetary type;
- with a differential – with mechanical blocking, and electrohydraulic control.
Brakes: operating brakes are multi-disk, oil-lubricated, located on drive pinion shafts of
hub drive. Operating brakes control is interlocked with pneumatic drive of trailer brakes. Oper-
ating brakes control drive is hydrostatic.
Parking brake is combined with operating brakes, with independent manual mechanical
control. Parking brake control is interlocked with pneumatic drive of trailer brakes.
Trailer brakes control drive is a combined pneumatic one, interlocked with tractor operat-
ing brakes control. Against order, tractor can be not equipped with pneumatic drive of trailer
brakes – tire inflation shall be carried out through a valve in the pneumatic compressor.
The rear power take-off shaft is continuous, four-speed, with smooth start, having two
modes – standard and economic.
The direction of rotation is clockwise as viewed from the side of the shaft end extension
butt end.
The first variant of supply:
The tractor is equipped with PTO 3 shaft end extension (20 splines) according to GOST
3480.
PTO 1c shaft end extension (8 splines) according to GOST 3480 and PTO 2 shaft end
extension (21 splines) according to GOST 3480 and ISO500 are included into tractor SPTA.
The second variant of supply:
The tractor is equipped with PTO 2 (21 splines) according to GOST 3480 and ISO 500.
PTO 1 (6 splines) according to ISO500 and PTO 3 shaft end extension (20 splines) ac-
cording to ISO500 are included into tractor SPTA.
Front PTO is continuous, one-speed. PTO 2 shaft end extension (21 teeth) complies with
GOST 3480. The direction of rotation is clockwise as viewed from the side of the shaft end ex-
tension butt end.
The transmission hydraulic system provides the following:
- switching of GB reduction unit passes, engagement of GB friction clutches, RPTO
drives, FPTO drive, FDA drive, differential lock;
- filtration of transmission oil;
- pressure feed lubrication of gearbox bearings, RA planetary gear reducer, FDA bear-
ings; - operation of the clutch hydraulic booster.
The steering is hydrostatic. The feed pump is gear-type, the direction of rotation is left.
The dosing pump is gerotor-type with open center, without steering response. The type of rota-
tion mechanism is two hydraulic cylinders (Ц50x250) of bidirectional action and a steering
linkage.
The front driving axle is portal-frame, with planetary-cylindrical final gears. The main
drive is a pair of bevel gears with circular teeth. The differential is self-locked, with increased
friction. The FDA is driven from the gearbox through the frictional hydraulically-operated clutch
and the crankshaft. The FDA control is electro-hydraulic.
The hydraulic lift linkage is universal with electrohydraulic control, on the basis of an ax-
ial-piston pump, providing depth, draft, position and combined adjustment for soil treatment.
The hydraulics has got an integrated unit consisting of four operating service sections of the
distributor with electrohydraulic joystick control, with a possibility to program functions (EHS)
and a regular section of EHR23-LS type to operate the real lift linkage. Four pairs of rear inde-
pendent outlets provide for adjustment of the work fluid supply at each outlet. There is a front
pair of outlets, which is connected to any pair of rear outlets through fast coupling clutches,
when there is a hydraulic implement coupled with the tractor FLL.
Free drain is available at the back and at the front for tractor operation with hydraulic
units with constant delivery, for example, with hydraulic motors.

tunity for coupling of implements of category 2 according to ISO 730 and lift linkage 2 ac-
cording to 10677 to RLL.
The front lift linkage (against order) is a three-point linkage of category 2 under ISO
