BRIEF DESCRIPTION
The BELARUS 1523/1523.3 agricultural
power-intensive wheeled tractor of the
3.0 tf traction class with the 4x4 wheel-
drive arrangement is intended for per-
forming various jobs with attached
mounted, semi-mounted, trailed machin-
ery and implements, load handling facili-
ties, harvesting complexes, and in run-
ning stationary agricultural machines off
the PTO shaft, as well as in road trans-
port missions in various climatic zones.
The tractor is equipped with a six-
cylinder, turbocharged in-line engine.
The power-train mechanisms: trans-
mission clutch, speed gearbox, rear
axle with a differential lock-up fea-
ture, rear power take-off shaft with
double-reduction (540 and 1000 rpm)
independent and synchronous (3.3 and
6.2 revolutions per meter of travel) are
located immediately after the engine.
Clutch: dry double-disk, closed-type,
with a hydrostatic control drive.
Gearbox: synchromesh, fixed-ratio,
range-type; assures 16 forward speeds
and 8 reverse speeds
∗
.
Running Gear: rear driving wheels, front
driving and steerable wheels. Front
wheel tyre dimensions 420/70R24, rear-
wheel tyres – 520/70R38.
Front Driving Axle: portal-type, with
detachable half-axle housings and
spur planetary reduction gearings of
the final drive.
The Steering control of the tractor is a
hydrostatic steering unit consisting of a
gear feeding pump, gerotor-type meter-
ing pump and two differential hydraulic
cylinders that ensures simple and easy
∗ 24 forward speeds and 12 reverse speeds
optionally.
control of the tractor when performing
various works. The steering control en-
sures the turn of the steerable wheels
and reduces the force to be applied to
the steering wheel in case of change of
the tractor motion direction.
To improve the traction performance
and steerability of the tractor, addi-
tional counterweights can be installed
on the fore bar.
The RHL Control Hydraulic System
with the BOSCH integral block, made
up of a slide-valve distributor to control
external hydraulic cylinders and elec-
tromagnetically controlled regulator
ensures the operation of the tractor cou-
pled with agricultural machinery and im-
plements using the draft, position or
combined control of tool position rela-
tive to the tractor framework, as well
as power take-off to drive tools of the
agricultural machines.
The tractor is equipped with a pneu-
matic system for operating the hydrau-
lically-actuated trailer brakes, and sin-
gle-line and dual-line brake system.
The Tractor Brakes
are multiplate ones
with hydrostatic actuator/ They are lo-
cated on driving pinions of the hub
drives.
