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.
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 recommenda-
tions, bolt torques, etc. The engine warranty is backed by the
engine manufacturer. Special attention should be paid to
applicable data which will not be duplicated here.
Belts
Inspect belts frequently for wear and serviceability.
Replace a belt that shows signs of:
• severe cuts
• tears
• separation
• weather checking
• cracking
• 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 the belt will lose power and slip excessively.
Never pry a belt to get it on a pulley as this will cut or dam-
age 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 Blades
Mower Blade Maintenance
IMPORTANT: Refer to the Safety section of this manual for
blade handling safety information.
Refer to the Mower Blade Replacement section for blade
removal and installation.
Check the mower blades daily, they are the key to power
efficiency and well groomed turf. Keep the blades 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.
Sharpen the blades following the pattern shown. Touch-up
sharpening can be done with a file. Figure 4-8
After grinding the blades, check for balance. Blade balanc-
ing can be done by placing the blade on an inverted line

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 H-Bar steering lever in the neu-
tral position immediately and place the neutral lock/
park brake lever in the park brake position. Inspect
the machine and involve your Hustler
®
dealer to
resolve the problem before continuing to operate.
Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves and use extra caution
when servicing them.
Always check for blade damage:
• if mower strikes a rock, branch or other for-
eign object during mowing!
• or if an abnormal vibration occurs while oper-
ating.
Make all necessary repairs before resuming opera-
tion.
