MAINTENANCE

Safety System

The machine is equipped with a safety system
that prevents starting or driving under the
following conditions.
The engine can only be started when:
• the mower deck is disengaged.
• the steering controls are in the outer, locked
neutral position.
• the park brake is on.
Make daily inspections to ensure that the safety
system works by attempting to start the engine
when one of the conditions is not met. Change
the conditions and try again.
If the machine starts when one of these
conditions is not met, turn the machine off and
repair the safety system before using the machine
again.
Make sure the engine stops when the park brake
is not engaged and the operator leaves the
seated position.
Check that the engine stops if the mower blades
are engaged and the driver temporarily moves off
the driver's seat.
IMPORTANT INFORMATION To be able to
drive, the driver must sit in the seat and release
the park brake before the steering controls can
be moved into the neutral position, otherwise
the engine will stop.

Tire Pressures

All tires must be at 15 psi / 103 kPa / 1 bar.
IMPORTANT INFORMATION DO NOT add
a tire liner or foam fill material to the tires.
Excessive loads created by foam filled tires will
cause premature failures.
Only use O.E.M. specified tires.
V-belts
Check every 100 hours of operation. Check for
severe cracking and large nicks.
NOTE: The belt will show some small cracks in
normal operation.

Deck Belt

Deck Belt Removal
Park the mower on a level surface. Engage the
park brake. Lower the deck into the lowest cutting
position.
1. Remove foot plate and belt shields.
2. Remove dirt or grass that may have
accumulated around the cutter housings and
entire deck surface.
3. With a 1/2" breaker bar and using the square
opening in the idler arm, shift the arm counter
clockwise to relieve the tension on the belt.
4. Carefully lift the belt over the top of the cutter
housing pulleys.
5. Remove the belt guide hardware with a 1/2"
wrench and set belt guide aside.
