Charging the Battery
Test and, if necessary, recharge the battery after the tractor has been
stored for a period of time.
•
A voltmeter or load tester should read 12.6 volts (DC) or higher
across the battery terminals. See Figure 30.

•
Charge the battery with a 12-volt battery charger at a MAXIMUM
rate of 10 amps.
Battery Storage
When storing the tractor for extended periods, disconnect the negative
battery cable. It is not necessary to remove the battery.
All batteries discharge during storage. Keep the exterior of the battery
clean, especially the top. A dirty battery will discharge more rapidly.
The battery must be stored with a full charge. A discharged battery can
freeze sooner than a charged battery. A fully charged battery will store
longer in cold temperatures than hot. Refer to Figure 30.
Recharge battery whenever the specific gravity reading on a temperature
compensating hydrometer is less than 1.225. See Figure 30.
Jump Starting
WARNING
Failure to use this starting procedure can cause sparking, and the
gases in the battery to explode.
1.
Attach the end of the red jumper cable to the positive terminal (+)
of the charged battery.
2.
Attach the other end of the red jumper cable to the positive
terminal (+) of the low charge battery.
3.
Attach the end of the black jumper cable to the negative terminal
of the charged battery.
4.
Attach the other end of the black jumper cable to the frame of the
unit with the low charge battery.
Servicing Electrical System
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. Always use the same capacity fuse for replacement. If the
electrical system does not function, check for a blown fuse.
If you have a recurring problem with blown fuses, call 1-800-659-5917
to schedule electrical system service from Sears Parts & Repair.
There are several safety switches in the electrical system (PTO Switch,
PTO Clutch, Parking Brake/Drive Control Lever Switch, Seat Switch
and No Cut in Reverse Switch). If a function of the safety interlock
system described earlier is not functioning properly, have the electrical
system checked by your Sears Service Center or to schedule service,
simply contact Sears at 1-800-4-MY-HOME®.

TIRE MAINTENANCE
Check the tire air pressure before each use. Inflation pressure of the
rear tires is important for stability while the mower is in operation. If
the tire diameter is not equal between the two tires, the mower will pull
to one side. Keep the tires inflated to the recommended pressures.
Improper inflation will shorten the tire service life. See the tire side wall
for proper inflation pressures. Observe the following guidelines:
•
Do not inflate a tire above the maximum pressure shown on the
sidewall of the tire.
•
Do not reinflate a tire that has been run flat or seriously under
inflated. Have a qualified tire mechanic inspect and service the tire.
•
Balance inflation pressure between the rear tires to help maintain
straight travel (see tire side wall for proper inflation pressure).
•
Keep the valve caps tightened to prevent air pressure loss.
USING THE DECK WASH SYSTEM
When using the deck wash system, never engage the deck from any
position other than the operator's seat of the tractor. Do not use an
assistant or engage deck in the presence of any bystanders.
Use the Deck Wash System to rinse grass clippings from the deck's
underside and prevent the buildup of corrosive chemicals. Complete
the following steps after each mowing:
NOTE: Make certain the machine's discharge chute is directed away
from people, children, animals, and your house, garage, parked cars, etc.
1.
Attach the nozzle adapter to a standard garden hose connected
to a water supply.
2.
Move the tractor to an area within reach of the hose where the dis-
persal of wet grass clippings is not objectionable to you. Disengage
the PTO, engage the parking brake, and stop the engine.
3.
Pull back the lock collar of the nozzle adapter and push the
adapter onto one of the deck wash nozzles at either end of the
mower deck. Release the lock collar to lock the adapter on the
nozzle. See Figure 31.
