and regular reference and for ordering replacement
pads.

Never leave a running machine unattended. Always
turn off blade(s), place transmission in neutral, set
park brake, stop engine and remove key before
dismounting.

•

Stop engine and wait until blade(s) comes to a
complete stop before (a) removing grass catcher or
unclogging
chute, or (b) making any repairs,
adjusting or removing any grass or debris.

Turn off blade(s) when not mowing.

Only allow responsible individuals familiar with the
instructions to operate the machine. Know controls
and how to stop the machine quickly.

• Do not put hands or feet under cutting deck or near
rotating parts.

Mow only in daylight or good artificial light.

• Clear the area of objects such as rocks, toys, wire,
etc., which could be picked up and thrown by the
blade. A small object may have been overlooked
and could be accidentally thrown by the mower in
any direction
and cause injury to you or a
bystander. To help avoid a thrown objects injury,
keep children, bystanders and helpers at least 75
feet from the mower while it is in operation. Always
wear safety glasses or safety goggles dudng
operation or while performing
an adjustment or
repair, to protect eyes from foreign objects. Stop
the blade(s) when crossing gravel drives, walks or
roads.

Never carry passengers.

•

Disengage blade(s) before shifting into reverse and
backing up. Always look down and behind before
and while backing.

Use extra care when loading or unloading the
machine into a trailer or truck. This unit should not
be driven up or down a ramp onto a trailer or truck
under power, because the unit could tip over,
causing serious personal injury. The unit must be
pushed manually on a ramp to load or unload
properly.

Charging
If the unit 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 during and for some time
after charging. Charge battery in a well
ventilated area and do not allow a spark or
an open flame near the battery.

Worn Blade Edge j_"
Blade Separation

Wind Wing

Figure 23
It is extremely important that each cutting blade
edge be ground equally to maintain proper blade
balance. An unbalanced blade will cause excessive
vibration when rotating at high speeds, 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.

FUSE
A fuse is installed in your tractor's widng harness to
protect the tractor's electrical system from damage
caused by excessive amperage. Always use the
same capacity fuse for replacement. If the electrical
system does not function, or your tractor's engine
will not crank, first check to be certain that the fuse
has not blown. It can be found under the hood
mounted behind the top of dash panel on the
support bar. Pull the fuse out and compare it with
Figure 24 to determine if it is good or bad.

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.
