Removing the Hydraulic Motor

Follow these steps to remove the hydraulic motor:

DANGER

To avoid bodily injury or death from unexpected startup of the machine, always stop the engine and remove
the key from the ignition before leaving the operator’s seat for any reason.

1. If the machine is connected to the windrower, lower

header to ground.

2. Stop the engine and remove the key.

3. Disconnect case drain hose (A) from motor (B).

4. Disconnect pressure and return hoses at

ttings (C).

IMPORTANT:

To protect the motor from contamination and
prevent spillage of excess

uid, install caps and

plugs on open

ttings and hoses.
