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.
IMPORTANT:
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 blade
spindle hex flange nut to between 70 ft-lbs (95N-m) and
90 ft-lbs (122 N-m).
Battery
The battery is sealed and is maintenance-free. Acid
levels cannot be checked.
WARNING:
Shield eyes (e.g. goggles, face
shield) and protect skin and clothing when
handling battery acid or a battery containing
acid.
•
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.
Jump Starting
WARNING:
Never jump start a damaged or
frozen battery (a battery can be identified as
frozen if its sides are bulged out, it’s frosty and
it feels very solid). Be certain the vehicles do
not touch, and ignitions are off. Do not allow
cable clamps to touch.
1.
Connect positive (+) cable to positive post (+) of
your tractor’s discharged battery.
2.
Connect the other end of the (+) cable to the
positive (+) post of the jumper battery.
3.
Connect the second negative (–) cable to the
negative (–) post of the jumper battery.
4.
Make the final connection on the engine block of
the stalled tractor, away from the battery. Attach to
a unpainted part to assure a good connection.
IMPORTANT:
If the jumper battery is installed on a
vehicle (i.e. car, truck), do NOT start the vehicle’s
engine when jump starting your tractor.
5.
Start the tractor (as instructed on page 17).
6.
Set the tractor’s parking brake before removing the
jumper cables, in reverse order of connection.
7.
Allow the tractor’s engine to run for 15 minutes
before shutting it off to allow the alternator time to
charge the discharged battery.
IMPORTANT:
1.
Battery wires must be connected to the correct
terminals. Reversing them could change the
polarity and damage engine’s alternating system.
2.
Do not jump-start a damaged battery.
3.
When storing the battery, disconnect the negative
terminal and store with full charge.
Charging
WARNING:
Batteries give off an explosive
gas while charging. Charge the 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.
