4.7 PREMIUM HYDRAULICS (OPTION)
Premium hydraulics is installed on the tractor as additional equipment. Due to large number of hydraulic
functions, tractor enables the user with a wide spectre of use and is suitable for work in different fields.
Premium hydraulics, beside standard hydraulic control, is also consisted of:
1. Control element (four control levers) ; intended for lifting/lowering front and rear hydraulic,
lower connection arm or activating quick couplings (connections);
2. Quick coupling (implements) ; with premium hydraulics, there are many quick couplings
installed on the tractor for wide spectre of use;
3. Choke ; intended for:
a. Soft start or prevention of sudden thrust of connection shaft when activating solenoid
valve;
b. Regulation of speed of cylinder movement of rear hydraulic lift mechanism;
4. Valve 3/2 ; upon activation of solenoid valve, ensures soft start of connection shaft (control
through PTO switch);
5. Valve 2/2 ; automatically activates upon connection of switch of rear connection shaft and
differential lock. Its function is to supply oil to requested hydraulic components;
6. Three-way directional valve ; transforms two-way functioning hydraulic cylinder into one-way or
vice versa.
