HYDRAULIC SYSTEM

HYDRAULICS CONTROL PANEL 

Hydraulics control panel is located in the 
area of the right wing. 
Controlling the rear three-point hitch is 
enabled by the inner hydraulic circuit (1). 
Controlling outer hydraulic circuits (cou-
plers) is enabled by outer hydraulic cir-
cuit (2). 
 
 
 
 
 
 
 
 
 
 

WAYS TO REGULATE INNER HYDRAULIC CIRCUIT 

Hydraulic system allows of three ways to regulate the lifting of the rear three-point 
hitch: 
Position regulation (img. 1) – the tool connected to the rear three-point hitch is auto-
matically kept in the same height (position) with regard to the tractor. 
Mixed regulation (img. 2) – a combination of position and power regulation. Suitable 
mainly for tilling areas of different soil resistance. 
Power regulation (img. 3) – the tool connected to the three-point hitch is automati-
cally being adjusted depending on changing soil resistance. 
 
All the regulations can also be used when working with a tool equipped with a sup-
port wheel in so-called free (floating) position.
