Two hydraulic valve blocks with multiple cartridges are used
for the various windrower functions and are controlled by
the windrower control module (WCM) according to the
inputs from the Operator. The valve blocks are located
behind the left cab-forward side platform.
The valve blocks do not require any scheduled
maintenance other than to check for leaking fittings or loose
electrical connections. If service is required, contact your
