Cleaning the Engine And Deck
Any fuel or oil spilled on the machine should be wiped off
promptly. Do NOT allow debris to accumulate around the cooling
fins of the engine or on any other part of the machine.
IMPORTANT: The use of a pressure washer to clean your
tractor is NOT recommended. It may cause damage to electrical
components, spindles, pulleys, bearings or the engine.
Deck Wash System™ (If equipped)
Some tractors come fitted with a Deck Wash System™, which
is used to rinse grass clippings from the deck’s underside and
prevent the buildup of corrosive chemicals. Other tractors may
have a deck wash plug, allowing for a Deck Wash System™ that
can be added at a later time. If this is the case, a hex bolt and
washer can be found on your tractor’s deck surface and can be
replaced with a water port to be used as part of a separately-
available deck wash system.
NOTE: Refer to the Attachments & Accessories section of this
manual for information regarding this and other separately-
available attachments and accessories for your tractor.
To utilize the Deck Wash System™, complete the following steps
AFTER EACH MOWING:
1. Drive the tractor to a level, clear spot on your lawn, near
enough for your garden hose to reach.
CAUTION: Make certain the tractor’s discharge
chute is directed AWAY from your house, garage,
parked cars, etc.
2. Disengage the PTO (Blade Engage), set the parking brake
and stop the engine.
3. Thread the hose coupler (packaged with your tractor’s
Operator’s Manual) onto the end of your garden hose.
4. Attach the hose coupler to the water port on the deck’s
surface. See Figure 6-3.

water port on your deck’s surface.
