1.7.2 Hydraulic supply via the power beyond port
The connection points between forage wagon and tractor are:
Pressureless return line (G) = oil return from forage wagon to tractor
Coupler socket (B) = oil supply via additional control unit
Item Designation Remark
A Power beyond port On the tractor. Is not used (closed).
B Coupler socket On the tractor. Directs the volume flow from the LS pump to
the forage wagon (via the additional control unit).
C Additional control unit On the tractor. Controls the volume flow from the pump via the
coupler socket (B) to the forage wagon. In the neutral position,
the LS signal line (D) is connected to the tank = no pressure
build-up is possible.
In working position:
• the volume flow from the pump is directed to the forage
wagon
• the load pressure of a consumer on the forage wagon
is directed into the LS pump via the LS signal line (D).
D LS signal line Directs the load pressure from a port on the forage wagon to
the LS pump.
E LS signal port On the tractor. Is not used.
F Shuttle valve Is pressed up by the signal pressure. The signal pressure is
directed to the pump via the signal line (D).
G Pressureless return line On the tractor. Directs the returning oil flow to the tractor.
