4.7.2 DESCRIPTION OF CONTROL ELEMENTS FOR HYDRAULICS
Control element is a steering unit with control levers, with which we direct oil flow from tractor's
pressure circuit to hydraulic outputs of internal or external hydraulic users.
The tractor is equipped with two control elements with three or four control levers. Each lever performs
certain function through control valve.
4.7.3 CONTROL VALVES
Control valves regulate oil flow from pressure line to certain implement. There are two types of control
valves – one-way and two-way.
One-way functioning 5/3-directional control valve (see chapter "DESCRIPTION OF CONTROL
ELEMENTS FOR HYDRAULICS – CONTROL VALVES")
Two-way functioning 6/3-directional control valve (see chapter "DESCRIPTION OF CONTROL
ELEMENTS FOR HYDRAULICS – CONTROL VALVES")
Two-way functioning 6/4-directional control valve
Two-way functioning control valve is used for regulating implements with two-way functioning hydraulic
cylinder.

Control lever has four positions:

Position "1" – supply of oil under pressure, control lever returns to neutral position automatically
