1. 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.
WARNING: Failure to use this
procedure could 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 neces-
sary, 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.
Cutting Blades
WARNING: Be sure to shut the
engine off, remove ignition key,
disconnect the spark plug wire(s)
and ground against the engine to
prevent unintended starting before
removing the cutting blade(s)
for sharpening or replacement.
Protect your hands by using heavy
gloves or a rag to grasp the cutting
blade.
WARNING: Periodically inspect
the blade spindles for cracks or
damage, especially if you strike a
foreign object. Replace immedi-
ately if damaged.
The blades may be removed as follows:
1. Remove the deck from beneath the tractor, (refer to
Cutting Deck Removal) then gently flip the deck over
to expose its underside.
2. Place a block of wood between the center deck hous-
ing baffle and the cutting blade to act as a stabilizer.
See Figure 6-7.
3. Rremove the hex flange nut that secures the blade to
the spindle assembly. See Figure 6-7.
Figure 6-7
Figure 6-8
4. To properly sharpen the cutting blades, remove equal
amounts of metal from both ends of the blades along
the cutting edges, parallel to the trailing edge, at a 25°
to 30° angle. See Figure 6-8.
IMPORTANT: If the cutting edge of the blade has already
been sharpened or if any metal separation is present,
replace the blades with new ones.
• It is important that each cutting blade edge be ground
equally to maintain proper blade balance.
• 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.
