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 / park brake controls are in the
outer, locked neutral position, making sure
of full parking brake engagement for a safe
startup.
NOTE: If the steering / park brake controls are not
holding in the full outboard position, the tension
can be adjusted. (See Park Brake in this section).
Make daily inspections to make sure that the
safety system works. 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.
Make sure the engine stops if the mower blades
are engaged and the driver leaves the seated
position.
IMPORTANT INFORMATION To drive, the
driver must sit in the seat and the steering /
park brake controls must be moved into the
engaged (outer) position. Otherwise the engine
will stop.
Caster Wheels
Check every 200 hours. Check that wheels rotate
freely.
To replace, remove nut and caster bolt. Pull the
wheel out of the fork. Install in reverse order.
Tighten caster bolt. Torque to 50 ft-lbs (67.8 Nm).
NOTE: Tire must rotate freely but axle spacers
must not. If wheels do not rotate freely take the
unit to the dealer for service.

Anti-scalp Rollers
Anti-scalp rollers keep the deck in the proper
position to help prevent scalping in most terrain
conditions. Do not adjust the rollers to support the
deck.
IMPORTANT INFORMATION Adjust anti-
scalp rollers with the mower on a flat level
surface. To avoid deck damage, the anti-scalp
rollers must not be adjusted to support the
deck.
Anti-scalp rollers can be set in three positions.
• Upper 1-1/2" to 2-1/2" (38 mm - 64 mm) grass
• Middle 2-1/2" to 4" (64 mm -102 mm) grass
• Lower 4" to 5" (102 mm - 127 mm) grass
The rollers must be approximately 1/4" (6.35 mm)
from ground. Do not adjust the rollers to support
the deck.
Cleaning
CAUTION! Always wear eye
protection when cleaning and
washing.
Regular cleaning and washing, especially under
the mower deck, will increase the machine's life-
span. Make it a habit to clean the machine directly
after use (after it is cooled), before the dirt sticks.
Do not spray water on the top of the mower deck.
Use compressed air to clean the top side of
mower deck. Regularly clean deck and underside
of the deck with normal water pressure. Do not
use a high pressure washer or steam cleaner.
Avoid spraying engine and electrical components
with water.
Do not rinse hot surfaces with cold water. Let unit
cool before washing.
Hardware
Check daily. Inspect the entire machine for loose
or missing hardware.
