CLEANING THE ENGINE AND DECK
Any fuel or oil spilled on the machine should be
wiped off promptly. Do NOT allow grass, leaves, and
dirt to accumulate around the cooling fins of the
engine or on any other part of the machine,
especially the pulleys and other moving parts.
Clean the underside of the deck with a wisk broom,
putty knife or forced air after each mowing.
IMPORTANT: The use a pressure washer or
garden hose to clean your tractor is NOT
recommended. It may cause damage to electrical
components, spindles, pulleys, bearings or the
engine. The use of water will result in a shortened
life of the tractor and reduce its serviceability.
CUTTING DECK REMOVAL
WARNING: Before performing any
maintenance, move the PTO lever, or PTO
knob into the disengaged (OFF) position,
engage the parking brake, turn the ignition
key to the OFF position and remove the
key from the switch
.
Several attachments are available for your tractor.
To mount some of these attachments and in order to
perform certain maintenance procedures, the deck
must be removed from the tractor. To properly
remove the cutting deck, proceed as follows:
WARNING: Do NOT remove deck
immediately after operating the tractor.
Allow the engine and other moving parts
ample time to cool down.
• Move the PTO lever, or PTO knob into the
disengaged (OFF) position and engage the
parking brake.
• Lower the deck by moving the lift lever into the
bottom notch on the right fender.
• Grasp the PTO idler pulley bracket (PTO
engagement plate on manual PTO units) and
pivot it toward the discharge chute to relieve
tension on the belt.
• Remove the deck belt from around the electric
PTO clutch (the bottom portion of the engine
pulley on manual PTO units) and from around
the PTO idler pulley(s).
NOTE: On units equipped with a 46-inch deck, the
bottommost belt on the deck does NOT need to be
removed in order to remove the deck.
• Looking at the cutting deck from the right side
of the tractor, locate the deck support pin on
the rear right side of the deck.
• Pull the deck support pin outward to release
the deck from the deck lift arm. See Figure 14.
• Rotate the pin slightly toward the rear of the
tractor and release the pin into the hole
provided.
• Repeat the above steps on the left side of the
tractor.
• Move the lift lever into the top notch on the
right fender to raise the deck lift arms out of
the way.
• 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. Do NOT let the deck fall to the ground.
• Gently slide the cutting deck (from the right
side) out from underneath the tractor.
