Coupling the hydraulic hose lines

All hydraulic hoses 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 machine 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:

NOTE
When the adjustment of the front furrow width and the working width are coupled via a switch tap, the front furrow width is also adjusted via the red tractor control unit.
IMPORTANT
Implement damage due to insufficient hydraulic oil return flow
On the tractor side, only use lines that correspond to the nominal width of red T of the implement or larger for the pressureless hydraulic oil return flow.
Select short return paths.
Connect the pressureless hydraulic oil return flow to the intended coupling before all of the other hydraulic connections.

If the implement has a leakage oil line:

couple the leakage oil line in the intended coupling.
Install the supplied coupling sleeve on the pressureless hydraulic oil return.
  1. Depressurise the hydraulic system between the tractor and the machine using the tractor control unit.
  2. Clean the hydraulic connectors.
NOTE

If the hydraulic hose lines are incorrectly connected, the hydraulic functions may be faulty.

  1. Couple the hydraulic hose lines 1 to the hydraulic sockets of the tractor according to the marking 2.

The hydraulic connectors lock perceptibly.

IMPORTANT
Damage to the supply lines when turning the plough bodies
Before turning the plough bodies, remove all of the supply lines from the hose cabinet.
Swivel the hose cabinet into transport position.
  1. Route the hydraulic hose lines with sufficient freedom of movement and without chafing points.
