D.Electrical Circuit
Danger:
Read General Safety Precautions Nos. 9 and 10.
1. Battery: The battery is located beneath the
operator’s seat. If so equipped, remove the
fillcaps and check the level of the liquid elec-
trolyte in the battery every 50 operating hours.
If the level in any of the six cells has dropped
below the bottom of the split ring inside the fill
hole, refill the cell with distilled water. To keep
the outside of the battery clean, brush on a
strong solution of bicarbonate of soda and
water and rinse with clean water. Keep the
contacts and cable ends clean with a wire
brush and make sure the connections are
tight. Coat the terminals with petroleum jelly
to prevent corrosion.
2. Battery Removal
Warning:
When removing the cables from the battery
follow these steps to avoid a short between
the wrench and the frame.
a. Remove the negative (black) cable.
b. Remove the positive (red) cable.
c.
Release the hold down straps.
d. Remove the battery without tipping.
3. Battery Storage: When storing the mower for
long periods of time the following guidelines
should be performed.
a. Disconnect the battery cables from the ter-
minals and remove the battery.
b. Clean the battery before storing. A dirty
battery will lose its charge over time.
c. Store the battery with a full charge. A dis-
charged battery will freeze (refer to the
table below).
Specific Gravity Freezing Temp (°F)
1.265 -71
1.250 -62
1.200 -16
1.150 5
1.100 16
d. Recharge battery when ever the specific
gravity value is less than 1.225
4. Installing the Battery
Note:
The battery is delivered from the fac-
tory fully charged and filled with electrolyte.
a. Attach the positive (red) cable.
b.
Attach the negative (black) cable.
c. Attach the rubber battery strap.
5. Jump Starting
Warning:
Failure to use this starting procedure can
cause sparking, and the gases in the battery
to explode.
a. Attach the end of the red jumper cable to
the positive terminal (+) of the charged bat-
tery.
b. Attach the other end of the red jumper
cable to the positive terminal (+) of the low
charge battery.
c. Attach the end of the black jumper cable to
the negative terminal of the charged bat-
tery.
d. Attach the other end of the black jumper
cable to the frame of the unit with the low
charge battery.
6. Fuses: There is one fuse located in the wiring
between the battery and ignition start switch.
This is a standard plug-in type automotive
fuse rated at 20 amp.
7. Safety Switches: There are five safety
switches in the electrical circuit which control
the engine. They are (1) the blade clutch
switch, (2) the parking brake/lap bar switch,
(3) the seat switch, (4 and 5) the no cut in
reverse switches.They operate so that in
order to start the engine, the blade clutch
switch must be off, the parking brake must be
engaged, and both steering levers must be in
the neutral position. Once the engine is
started, the seat must be occupied and the
parking brake must be released before either
of the steering levers can be moved. Also, the
seat must be occupied before
the blade
clutch switch can cause the blades to rotate.
8. Safety Switch Operation Checks: The fol-
lowing operational checks should be made
daily.
a. Blade Clutch Switch: Sit in the operator’s
seat. With both steering levers in the neu-
tral position and the parking brake
engaged, turn the blade clutch switch “on”
and try to start the engine. The engine
should not start. If it does, the blade clutch
switch must be replaced. If the engine
does not start, turn the blade clutch switch
“off” and start the engine. Now turn the
blade clutch switch “on” and the blades
