angle between the boom and arm should be 90° to 110°.
When only one side is stuck in mud, use the bucket to raise the
track, then lay boards or logs and drive the machine out.
Tracks on Both Sides Stuck

cannot move, use the procedure given above to lay logs or timber.
dig the bucket into the ground at the front, operate the arm in the
same way as when digging, and set the travel lever to FORWARD
