Coupling hydraulic hose lines
All hydraulic hoses 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. Decals that match the marking are affixed on the machine to illustrate the respective hydraulic functions.
The tractor control unit is used in different activation types, depending on the hydraulic function:
