Once the system is filled with oil, lift rear of mower until
rear tires are off the ground. Start engine, release parking
brake, and 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), then 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 subsequent usage. These bypass levers
also serve as a neutral for moving the mower without the
engine running.
SECTION 2: DRIVE BELT
Shown on the right is a typical pump belt tensioner for
your ZT model mower.
Tightening the two ¾˝ jam nuts on the right side will
increase the belt tension on all models. Factory setting is
about .030˝ (about the thickness of a credit card) between
coils as shown.
