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™
A hex plug can be found on your tractor’s deck surface.
See Fig. 6-2.
This plug can be replaced with a water port to be used as
part of a separately-available deck wash system.
Use the Deck Wash System™ to rinse grass clippings
from the deck’s underside and prevent the buildup of
corrosive chemicals.
NOTE: Refer to page 28 for information regarding this
and other separately-available attachments & acces-
sories for your tractor.
Cutting Deck Removal
NOTE: Models equipped with a 38-inch deck have
one deck idler pulley. Models equipped with a 42- and
46-inch deck have two deck idler pulleys.
To remove the cutting deck, proceed as follows:
1. Place the PTO (Blade Engage) lever in the disen-
gaged (OFF) position and engage the parking brake.
2. Lower the deck by moving the deck lift lever into the
bottom notch on the right fender.
3. Remove the belt from around the tractor’s engine
pulley and idler pulley(s). Refer to Changing the Deck
Belt on page 26 for detailed instructions.
4. Looking at the cutting deck from the left side of the
tractor, locate the hair pin clip that secures the deck
support rod on the rear left side of the deck.
See Fig. 6-3.
5. Remove the hair pin clip that secures the deck
support rod, and carefully remove the deck support
from the deck lift arm.
6. Repeat the above steps on the tractor’s right side.
7. Move the deck lift lever into the top notch on the right
fender to raise the deck lift arms up and out of the
way.
8. Carefully remove the PTO cable from the rear of
the cutting deck by removing the hair pin clip which
secures it. Remove the spring from the deck idler
bracket. See Fig. 6-4.
9. Gently slide the cutting deck toward the front of the
tractor allowing the hooks on the deck to release
themselves from the deck stabilizer rod.
10. Gently slide the cutting deck (from the right side) out
from underneath the tractor.
