Specifications

1. Remove the large bolt and lock washer which
holds the blade and adapter to the blade spindle.
2. Remove the blade and adapter from the spindle.
3. If the blade or blade adapter needs replacing,
remove the two small bolts, lock washers and
nuts which hold the blade to the adapter (does
not apply to all models).
B. Sharpening
Remove the cutting blades by following the directions
of the preceding section.
When sharpening the blades, follow the original angle
of grind as a guide. It is extremely important that each
cutting edge receives an equal amount of grinding to
prevent an unbalanced blade. An unbalanced blade
will cause excessive vibration when rotating at high
speeds, may cause damage to the mower and could
break, causing personal injury.
The blade can be tested for balance by balancing it
on a round shaft screwdriver. Remove metal from the
heavy side until it balances evenly.
NOTE: It is recommended that the blade always be
removed from the adapter for the best test of balance.
C. Reassembly
Before reassembling the blade and the blade adapter
to the unit, lubricate the spindle and the inner surface
of the blade adapter with light oil (or engine oil).
Lubricating the bolt holes, bolts and inner surface of
the nuts is also recommended.
When replacing blades, be sure to install the blade
with the side of the blade marked "Bottom" (or with
part number) facing the ground when the mower is in
the operating position.
Blade Mounting Torque
Center Bolt: 450 in. lb. min., 600 in. lb. max.
Blade Adapter Bolts (if applicable): 200 in. lb. min.,
350 in. lb. max.
To ensure safe operation of your unit, all nuts and
bolts must be checked periodically for correct tight-
ness.
BATTERYCAREAND MAINTENANCE
CHECK FLUID LEVEL
Check fluid level inside each cell of the battery every
two weeks and before and after charging. Always
keep level just below the split rings.
Add only distilled water. Never add additional acid
or any other chemicals to the battery after initial
activation.
NOTE: After operating the lawn tractor for a long
period of time, check the fluid level in the battery as it
can overheat and lose fluid.
CHARGING THE BATTERY
The engine is equipped with an alternator which
charges battery when tractor is operated. Under
normal conditions, the battery only needs to be
charged before, during and after off-season storage.
Follow the instructions under "Off-Season Storage."
To charge the battery: Make certain fluid level in
each cell is just below the split rings. Use a 12 volt
automotive charger which is rated at 6 amps. Charge
the battery to 1.260 minimum specific gravity.
REMOVING / INSTALLING / JUMP STARTING
&
WARNING: When removing or installing
the battery, follow these instructions to
prevent the screwdriver from shorting
against the frame.
Removing the Battery: Disconnect negative cable
first, then positive cable.
Installing the Battery: Connect positive cable first,
then negative cable.
Jump Starting
1. First, connect end of one jumper cable to the posi-
tive terminal of the good battery, then the other
end to the positive terminal ofthe dead battery.
2. 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
could cause sparking, and the gas in
either battery could explode.
CLEAN THE BATTERY
Clean the battery by removing it from the unit 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: incor-
rect initial activation, lack of water, adding chemicals
other than water after initial activation, undercharging,
overcharging, corroded connections, freezing. These
failures do not constitute warranty.
TIRES
Recommended operating tire pressure is
approximately 12 p.s.i. Maximum tire pressure under
any circumstances is 30 p.s.i. Equal tire pressure
should be maintained on all 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.
