it is important that each cutting blade edge be ground
equally to maintain proper blade balance. A poorly
balanced blade will cause excessive vibration and may
cause damage to the tractor and result in personal
injury.
The blade can be tested by balancing it on a round
shaft screwdriver. Grind metal from the heavy side until
it balances evenly.
When replacing the blade, be sure to install the blade
with the side of the blade marked "Bottom” (or with a
part number stamped in it) facing the ground when the
mower is in the operating position.
IMPORTANT: Use a torque wrench to tighten the blade
spindle hex flange nut to between 70 foot-pounds and
90 foot-pounds.
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.
IMPORTANT: If removing the battery for any reason,
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 cause 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: Batteries give off an explosive
gas while charging. Charge battery in a well
ventilated area and keep away from an open
flame or piiot iight as on a water heater, space
heater, furnace, clothes dryer or other gas
appliances.
Jump
A WARNING: When removing or installing
the battery, follow these instructions to
prevent the screwdriver from shorting against
the frame.
A
A
IMPORTANT: Never jump your tractor’s dead battery
with the battery of a running vehicle.
• Connect end of one Jumper cable to the positive
terminal of the good battery, then the other end to
the positive terminal of the dead battery.
• Connect the other Jumper cable to the negative
terminal of the good battery, then to the
frame of
the unit with the dead battery.
WARNING: Failure to use this procedure
couid cause sparking, and the gas in either
battery could explode.
Cleaning
Clean the battery by removing it from the tractor and
washing with a baking soda and water solution. If
necessary, scrape the battery terminals with a wire
brush to remove deposits. Coat terminals and exposed
wiring with grease or petroleum Jelly to prevent
corrosion.
Battery Failures
Some common causes for battery failure are:
• incorrect initial activation • undercharging
• overcharging • corroded connections
• freezing
These failures are NOT covered by your tractor’s
warranty.
Tires
Recommended operating tire pressure is
approximately 10 p.s.i. Maximum tire pressure under
any circumstances is 30 p.s.i. Equal tire pressure
should be maintained on ail tires.
When installing a tire to the rim, be certain rim is clean
and free of rust. Lubricate both the tire and rim
generously.
Never inflate to over 30 p.s.i. to seat
beads.
A WARNING: Excessive pressure (over 30
p.s.i.) when seating beads may cause tire/rim
assembly to burst with force sufficient to
cause serious injury.
Beit Replacement
A WARNING: Shut the engine off, remove
ignition key, set the parking brake, disconnect
the spark plug wire(s) and ground against the
engine to prevent unintended starting before
replacing belts.
For performing service on your tractor and in order to
properly mount some (separately available)
attachments, it may be necessary to remove the
tractor’s cutting deck. To due so, proceed as follows:
