• Re-attach the seat platform to the mower frame.
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.

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.

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. Figure 4-10
IMPORTANT: Never use hydraulic or automatic transmis-
sion fluid in this system; use only the specified motor oil.

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.

Remember, dirt is the primary enemy of any hydraulic sys-
tem.
Each transaxle has its own hydraulic expansion tank. The
tanks are located in front of the engine and behind the opera-
tor'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.
When the hydraulic system oil is cold, the fluid level should
be at the "Full Cold" line on the expansion tank. Use only SAE
20W50 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 the filter. Figure 4-11
Each transmission's filter is located per Figure 4-11. A
standard oil filter wrench is used to change the filter. The
threads are right handed. Use a Hustler
ment only.
IMPORTANT: When washing the mower, direct the spray
away (especially if using a power washer) from the transmis-
sion's seals to prevent water intrusion and to ensure compo-
nent performance.

Fluid Changing Procedure

1. Park the unit on a level surface.
