4.8 PREMIUM PLUS HYDRAULICS
Newer version of the tractor with Premium equipment has, beside existing hydraulics, additionally
integrated system of floating hydraulics with support. This keeps the operation of control elements,
connection shaft and chokes of rear hydraulic cylinders the same.
Besides existing Premium hydraulics, the following items are additionally installed:
1. Valve for pressure preparation ;
2. Battery , intended for storing hydraulic energy;
3. Control block , intended for supporting weight of the implement, in which the previous three-
directional valve for transformation of two-way cylinder into one way is also integrated.
