Once the system is filled with oil, lift rear of mower until rear tires are
off the ground. Start engine, release parking brake, stay clear of
moving rear tires. Next, pull the neutral bypass levers (located at the
rear of the frame, on either side of the muffler), move the drive arms
forward and backward 4 to 6 times slowly. This relieves any air that
may be trapped in the system. It may be necessary to add more oil to
the hydro overflow tank after 10-15 minutes of running. These bypass
levers also serve as a neutral for moving the mower without the
engine running.
