front of the right side transmission so that it can drain
into a suitable oil drain container.
5. With the hose in position, use a 10 mm wrench or socket
and open the valve approximately 4 turns in the
counterclockwise direction. Allow 10 minutes for engine
oil to adequately drain.
6. After oil is drained, close the valve by turning it in the
clockwise direction until it is fully closed.
7. Once the valve is closed, carefully remove the oil drain
hose and clean up any spilled oil.
IMPORTANT: All oil drips or spills must be cleaned off
of the exhaust system before operating the machine.
8. Clean the oil drain hose and store it appropriately. Figure

Engine Air Filter
Perform engine air filter maintenance per the Maintenance
Schedule shown elsewhere in this manual.
General Engine Maintenance
Detailed instructions and recommendations for break-in and
regular maintenance are specified in the Engine Owner’s
Manual. Please refer to this manual for engine servicing,
lubricating oil levels with quality and viscosity
recommendations, bolt torques, etc. The engine warranty is
backed by the manufacturer. Special attention should be paid to
applicable data which will not be duplicated here.
Fuel Evaporation System Filter
All Hustler
®
Raptor mowers have a fuel evaporation system
filter. This filter must be checked and replaced every 100 hours
or annually whichever comes first. Figure 4-4
Belts
Inspect belts frequently for wear and serviceability. Replace a
belt that shows signs of severe cuts, tears, separation, weather
checking and cracking, or burns caused by slipping. Slight
raveling of belt covering does not indicate failure, trim ravelings
with a sharp knife.
Inspect the belt pulley grooves and flanges for wear. A new
belt, or one in good condition, should never run against the
bottom of the groove. Replace the pulley when this is the case,
otherwise belt will lose power and slip excessively.
Never pry a belt to get it on a pulley as this will cut or damage
the fibers of the belt covering.
Keep oil and grease away from belts, and never use belt
dressings. Any of these will destroy the belt composition in a
very short time.
Mower Blade Maintenance
Check the mower blades daily, they are the key to power
efficiency and well groomed turf. Keep them sharp, a dull blade
will tear rather than cut the grass, leaving a brown ragged top on
the grass within a few hours. A dull blade also requires more
power from the engine.
Replace any blade which is bent, cracked or broken.

WARNING
If the pump belt fails, loss of control will occur especially
when operating on a slope. If you lose steering control
while operating the machine, place the steering con-
trol levers in the park brake position immediately.
Inspect the machine and involve your Hustler

dealer
to resolve the problem before continuing to operate.
WARNING
Never attempt to straighten a bent blade by heating, or
weld a cracked or broken blade as the blade may break
and cause serious injury. Replace worn or damaged
blades.
