DS00M060A
When the Powered Rear Axle switch in the combine cab is in the "Off" position, current is no longer supplied to the
solenoid valve (1), Figure 1 . This causes the spring-loaded spool in the solenoid to move away from the solenoid
coil. When this happens, hydraulic fluid flow from the low pressure spool will be closed off from port (A) to port (B)
(which flows to the pressure to engage side of the selector spool (2), Figure 2, in the "On" position) and allows fluid
to flow from port (A) to port (C), Figure 1 (pressure to disengage side of the selector spool).
