a) Stop engine, wait for all moving parts to stop, and remove key.
b) Locate filter under right rear corner of engine deck.
c) Carefully clean area around filter. It is important that no dirt or
contamination enter hydraulic system.
d) Unscrew filter to remove and allow oil to drain from reservoir.
IMPORTANT: Before reinstalling new filter, fill it with Mobil 1 15W-50 and
apply a thin coat of oil on the surface of the rubber seal.
Turn the filter clockwise until rubber seal contacts the filter adapter then
tighten the filter an additional 2/3 to 3/4 turn.
e) Fill reservoir as stated in Section 5.1.11.
f) Raise the rear of machine up and support with jack stands (or equivalent
support) just high enough to allow drive wheels to turn freely.
g) Start engine and move throttle control ahead to full throttle position.
Move the speed control levers to the full speed and run for several
minutes. Shut down machine and recheck oil level.
Do not change hydraulic system oil (except for what can be drained when
changing filter), unless it is felt the oil has been contaminated or been
extremely hot.
Changing oil unnecessarily could damage hydraulic system by introducing
contaminates into the system.
Wheel hub - slotted nut torque specification.
When tightening the slotted nut on the wheel motor tapered shaft:
