• Reconnect the two female spade connectors to
the seat switch. This must be completed so that
the safety circuit is functioning properly.
Figure 4-7
• Re-attach the seat platform to the mower frame.
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
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.
Hydraulic Pump Belt Adjustment
The transmission drive belt tension remains constant by
means of a tension idler and spring. There is no tension
adjustment of this belt. Figure 4-9
IMPORTANT: 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
transmissions (transaxles). Figure 4-10
IMPORTANT: Never use hydraulic or automatic
transmission fluid in this system; use only the specified
motor oil. Remember, dirt is the primary enemy of any
hydraulic system.
Each transaxle has its own hydraulic expansion tank. The
tanks are located in front of the engine and behind the
operator’s platform. Figure 4-10
Check the oil level in the hydraulic system after every 50
hours of operation or weekly, whichever occurs first. Check
more often if the system appears to be leaking or otherwise
malfunctioning.
The mower ships from the factory with SAE 20W50 motor oil
in the system. Use SAE 20W50 motor oil, 15W50 synthetic oil,
or 20W50 synthetic oil when changing the system oil and filter.
Hustler
®
Full Synthetic 20W50 Hydrostatic Transmission Oil is
recommended.
When the hydraulic system oil is cold, the fluid level should
be at the “Full Cold” line on the expansion tank.
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 transaxle every 2 years or 200
hours, whichever comes first.
Do not operate the mower without plugging the
mower’s wiring harness into the seat switch. This
switch is an important part of the safety start
interlock system. Serious injury can result if the
seat switch is not plugged into the mower’s wiring
harness.
Never operate the mower with a non-functioning
seat switch. Always reconnect the seat switch to the
mower harness.

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.
