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.

Activation type | Function | Symbol |

Latching | Permanent oil circulation | |
Momentary | Oil circulation until action is executed | |
Floating | Free oil flow in the tractor control unit |
