Coupling the hydraulic hose lines
All hydraulic hose lines are equipped with handles. The handles have colour markings with a 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 are applied on the implement for the markings, which illustrate the respective hydraulic functions.
The tractor control unit is used with different types of actuation, depending on the hydraulic function:
Type of actuation | Function | Symbol |
|---|---|---|
Latching | Permanent oil circulation | |
Momentary | Oil circulation until action is executed | |
Floating | Free oil flow in the tractor control unit |

- Depressurise the hydraulic system between the tractor and the implement using the tractor control unit.
- Clean the hydraulic plugs.
If the hydraulic hose lines are incorrectly connected, the hydraulic functions may be faulty.
- Couple the hydraulic hose lines 1 to the hydraulic sockets of the tractor according to the label 2.
The hydraulic plugs lock perceptibly.
- Route the hydraulic hose lines with sufficient freedom of movement and without chafing points.
