- correction of the operating depth;
- possibility of operation with the machines provided with height-related method of ad-
justment of the height of travel of the tools (the depth is adjusted by the carrier wheel of the
machine).
The hydraulic system provides the following methods of adjustment of the position of the
mounted and semi-mounted machines and their tools:
a) having no carrier wheels:
Power: the depth is adjusted in accordance with the draught resistance of the machine;
Position: the machine is held in the specified position relatively to the tractor body;
Combined: the power and position methods in any relationship;
b) provided with carrier wheels:
Combined: the power and position methods in any relationship.
The hydraulic system for controlling the mounted attachments ensures the possibility of
additional oil takeoff for providing the operation of the aggregated machines.
The tractor is provided with free hydraulic outlets for servicing the aggregated technical
means by means of he applied high-pressure hoses.
The oil consumption is 35...45 l/min (depending on the technical state of the hydraulic
pump). The oil takeoff by the hydraulic cylinders of the aggregated machine shall not exceed
16 l. The level in the hydraulic oil tank should be checked with the plugs of the working cyl-
inders retracted.
The shutting off and rupture members included in the spare parts and accessories kit of the
tractor (optionally) are provided for preventing the losses of oil when aggregating the tech-
nical means or unforeseen disconnection. The hydrostatic power intake is possible through
one of the outlets for supplying the special-purpose hydraulic motors. To avoid the overheat-
ing of the hydraulic system, the work pressure shall not exceed 11 MPa (110 kgf/cm
2
) that
corresponds to the power of 11 kW, not more. A separate pipeline (optional) is provided for
draining oil from the hydraulic motor with bypassing the distributor.
The tractor is equipped with fittings having the conditional flow passage Dc = 12 mm and
connection thread М20х1.5. In case of necessity of connection of the aggregated machines
with different thread, the required adaptors with the conventional flow passage of at least Dc
= 12 mm should be manufactured.
ATTENTION! The oil in the working cylinders of the aggregated machine shall be clean
and correspond to the brand used in the tractor. Failure to fulfil these requirements can
cause failure of the hydraulic units of the tractor.
The adaptation and modification of the structural elements of the hydraulic system
of the tractor except for those permitted by this Operating Manual is only allowed af-
ter consultation with the manufacturer.
5. Using the traction hitching mechanisms
The tractor can be equipped with traction hitch mechanisms of various types providing
the aggregation of trailed and semi-trailed machines, the coupling arrangements of which
meet the following requirements:
