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 rav-
eling 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 bot-
tom of the groove. Replace the pulley when this is the case, oth-
erwise, the 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 dress-
ings. Any of these will destroy the belt composition in a very
short time.
Hydraulic Pump Belt Adjustment
The transmission drive belt tension remains constant by
means of a tension idler and spring. There is no tension adjust-
ment of this belt. Figure 4-8
NOTE: Inspect the belt every 100 hours and replace as
needed. Replace the belt every 200 hours or every two (2) years
whichever comes first.
Hydraulic system
This mower is equipped with two integrated hydrostatic trans-
missions. Figure 4-9
IMPORTANT: Never use hydraulic or automatic transmis-
sion fluid in this system; use only motor oil as specified.
Remember, dirt is the primary enemy of any hydraulic system.
The hydraulic expansion tank is located in front of the engine
and under the operator’s platform. Figure 4-9
Check oil level in hydraulic system after every 50 hours of
operation or weekly, whichever occurs first. Check more often if
system appears to be leaking or otherwise malfunctioning.
Fluid level should be at the “Full Cold” line on the expansion
tank. Use only SAE 20W50 SL/SM service motor oil.
Initial system oil and filter change must be after the first 75
hours of use or 1 year whichever comes first. Thereafter, replace
filter and oil in each transmission every 2 years or 200 hours,
whichever comes first. NOTE: The filter guard must be
removed to access filter.
Each transmission’s filter is located per Figure 4-10. A stan-
dard oil filter wrench is used to change filter, threads are right
handed. Use a Hustler
®
approved filter element only.
Fluid changing procedure
1. Park the unit on a level surface. Place control levers in
the park brake position, disengage deck clutch, remove
ignition switch key and disconnect negative battery
cable.
2. Remove the three 1/4” filter guard screws and filter
guard. Clean any loose debris from around the filter.
Figure 4-11
3. Place an oil drain pan beneath the oil filter and remove
the oil filter from the transaxle.
4. After the oil has been drained, wipe the filter base surface
off and apply a film of new oil to the gasket of the new
replacement filter.
Figure 4-7
If the transmission 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
control levers in the park brake position immediately.
Inspect the machine and involve your dealer to resolve
the problem.

When washing the mower, direct the spray away (espe-
cially if using a power washer) from the transmission’s
seals to prevent water intrusion and to ensure component
performance
