Cutting Deck Removal
To remove the cutting deck, proceed as follows:
• Place the PTO (Blade Engage) lever in the
disengaged (OFF) position and engage the parking
brake.
• Lower the deck by moving the deck lift lever into the
bottom notch on the right fender.
• Remove the PTO belt (46" Deck)/ deck belt (42"
Deck) from around the tractor's engine pulley and
idler pulley(s). Refer to Changing The Deck Belt &
PTO Belt and Figure 26 and Figure 27.
NOTE:
On models with a 46-inch deck, it may be
necessary to remove the belt keepers from around the
engine pulley, in order to removes the PTO belt.
• Looking at the cutting deck from the left side of the
tractor, locate the deck support pin on the rear left
side of the deck. See Figure 22.

• Pull the deck support pin outward to release the
deck from the deck lift arm.
• Rotate the pin slightly toward the rear of the tractor
and release the pin into the hole provided.
• Repeat the above steps on the tractor's right side.
• 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.
NOTE:
Models with a 46-inch deck are equipped with
a short cable which controls the deck spindle brake. It is
necessary to unhook this cable in order to fully remove
the cutting deck from the tractor. Be certain to reattach
the cable when re-mounting the cutting deck.
• 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.
• Gently slide the cutting deck (from the right side)
out from underneath the tractor.
Tires
WARNING:
inflation pressure shown on the sidewall of the
tire.
The recommended operating tire pressure is:
• Approximately 10 psi for the rear tires
• Approximately 14 psi for the front tires
Refer to the tire sidewall for exact tire
IMPORTANT:
manufacturer's recommended or maximum psi. Do not
overinflate. Uneven tire pressure could cause the
cutting deck to mow unevenly.
Battery
The battery is sealed and is maintenance-free. Acid
levels cannot be checked.
• Always keep the battery cables and terminals clean
and free of corrosive build-up.
• After cleaning the battery and terminals, apply a
light coat of petroleum jelly or grease to both
terminals.
• Always keep the rubber boot positioned over the
positive terminal to prevent shorting.
If removing the battery for any reason,
IMPORTANT:
disconnect the NEGATIVE (Black) wire from it's
terminal first, followed by the POSITIVE (Red) wire.
When re-installing the battery, always connect the
POSITIVE (Red) wire its terminal first, followed by the
NEGATIVE (Black) wire. Be certain that the wires are
connected to the correct terminals; reversing them
could change the polarity and result in damage to your
engine's alternating system.
Charging
If the tractor has not been put into use for an extended
period of time, charge the battery with an automotive-
type 12-volt charger for a minimum of one hour at six
amps.
WARNING:
gas while charging. Charge battery in a well
ventilated area and keep away from an open
flame or pilot light as on a water heater, space
heater, furnace, clothes dryer or other gas
appliances.
