Coupling hydraulic hose lines

All hydraulic hose lines are fitted with handles. The handles have colored markings with code number or a code letter. The markings are assigned to the respective hydraulic functions of the pressure line of a tractor control unit. Stickers that match the marking are affixed on the implement to illustrate the respective hydraulic functions.

The tractor control unit is used in different activation types, depending on the hydraulic function:
