Cleaningthe EngineAndDeck
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.
On tractor models that do not come equipped with a deck wash
port already insalled, a hex plug can be found on your tractor's deck
surface. See Fig. 6-3. This plug can be replaced with a water port
to be used as part of a separately-available deck wash system.
The Deck Wash System
TM
is used to rinse grass clippings from the
deck's underside and prevent the buildup of corrosive chemicals.
NOTE: Refer to the Attachments & Accessories section of this
manual for information regarding this and other separately-
available attachments & accessories for your tractor.
