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. Stickers that match the markings 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:
Activation type | Hydraulic function | Symbol |
|---|---|---|
Latching | Permanent hydraulic oil circulation | |
Momentary | Hydraulic oil flow until action is executed | |
Floating | Free hydraulic oil flow in the tractor control unit |
Marking | Function | Tractor control unit | ||||
|---|---|---|---|---|---|---|
Yellow | Running gear | bringing into working position bringing into headlands position or transport position | Double-acting | |||
Green | Working depth of the concave disks | Increase Reduce | Double-acting | |||
- Depressurize the hydraulic system between the tractor and the implement using the tractor control unit.
- Clean the hydraulic plug connectors.
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 marking 2.
The hydraulic plug connectors lock tangibly.
- Route the hydraulic hose lines with sufficient freedom of movement and without chafing points.
