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.
C. Reassembly
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. Carefully align “star” on blade
with “star” on spindle. Secure with hex flange nut.
Blade Mounting Torque
Hex Flange Nut: 1080 in. lb. min., 1230 in. lb. max.
To ensure safe operation of your unit, all nuts and bolts
must be checked periodically for correct tightness.
BAHERY CARE AND MAINTENANCE
(TYPE “A” BAHERY)
Type “A” batteries are sealed and are maintenance free.
BAHERY CARE AND MAINTENANCE
(TYPE “B” BAHERY)
CHECK FLUID LEVEL
Check fluid level inside each cell of the battery every
two weeks and before and after charging. Always keep
level between maximum and minimum fill level.
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 (ALL BATTERIES)
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: Battery P/N 725-1705B—
Charge at 2-3 amps for one hour. Battery P/N 725-1707B
and 725-0453E—Charge at 6 amps for one hour.
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
positive terminal of the good battery, then the
other end to the positive terminal of the 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.
A 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 nec­
essary, scrape the battery terminals with a wire brush
to remove deposits. Coat terminals and exposed wir­
ing with grease or petroleum jelly to prevent corrosion.
BATTERY FAILURES
Some common causes for battery failure are: incorrect
initial activation, lack of water, adding chemicals other
than water after initial activation, undercharging, over­
charging, corroded connections, freezing. These
failures do not constitute warranty.
TIRES
Recommended operating tire pressure is approxi­
mately 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.
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.
A
BELT REMOVAL AND REPLACEMENT
A WARNING: Disconnect the spark plug
wire(s) and ground it against the engine.
Block the wheels of the unit.
NOTE: Figures 18, 22 and 23 are shown with the unit
tipped up for clarity. It is not necessary to tip the unit to
remove the belts.
However, if tipping the unit is desired, remove the
battery from the unit. To prevent gasoline leakage,
drain the gasoline, or remove the fuel tank cap, place a
thin piece of plastic over the neck of the fuel tank and
screw on the cap. Be certain to remove the plastic
when finished changing the belts. Block unit securely.
