The hydraulic system is intended for lifting and lowering of agricultural machines and implements attached in
the rear three point hitch.
Hydraulic equipment
Is made up from internal and external circuit. The source of pressure oil is gear pump.
Oil is taken from common filling of gearbox and final drive housing. Hydraulic pump is unswitchable. Pump is
in operation with engine running. Supplied amount 50 l/min.
The pressure derived in hydraulic set by hydraulic pump is limited by a locking valve to 18 MPa.
Hydraulic control panel
Means of internal hydraulic circuit regulation
NM13N101
Hydraulic system enables three means of heave three-point linkage control. Position regulation (fig.1) where
some tools connected in three-point linkage are kept automatically at constant height (position) to tractor.
Mixed regulation (fig. 2) which is the combination of position and power regulation. It is suitable mostly for
tillage on lots with different soil resistance. Power regulation (fig. 3), with which tools connected in three-point
linkage are automatically vertically adjustable depending on the change in soil resistance. All means of
re
ulation enable also work with tools which has su
ortin
wheel in the s
-called free
floatin
osition
The hydraulic control panel is located in the compartment
of the right mudguard.
The outer circuit of the hydraulics (A) enables control the
outer hydraulic circuits (quick couplers) in the front and the
rear part of the tractor and control of arms of the front
three-point hinge.
The inner circuit of the hydraulics (B) enables control of
the rear three-point hinge.
