Maintaining 

Your Lawn 

Tractor

Be sure to shut the 

engine off, remove 

ignition key, discon-

nect the spark plug 

wire(s) and ground 

against the engine to 

prevent unintended 

starting before remov-

ing the cutting blade(s) 

for sharpening or 

replacement. Protect 

your hands by using 

heavy gloves or a rag 

to grasp the cutting 

blade.

8.  Repeat the above steps on the tractor’s right side.
9.  Move the deck lift lever into the top notch on the right 

fender to raise deck lift arms up and out of the way.

10. Gently slide the cutting deck toward the front of the 

tractor allowing the hooks on the deck to release 
themselves from the deck stabilizer rod.

11. Gently slide the cutting deck (from the right side) out 

from underneath the tractor.

Tires

WARNING: 

Never exceed the maximum 

inflation pressure shown on the sidewall 
of tire.

The recommended operating tire pressure is:
•  Approximately 10 psi for the rear tires 
•  Approximately 14 psi for the front tires

IMPORTANT

: Refer to the tire sidewall for exact tire 

manufacturer’s recommended or maximum psi. Do not 
overinflate. Uneven tire pressure could cause the cutting 
deck to mow unevenly.

Battery

The battery is sealed and is maintenance-free. Acid 
levels cannot be checked.
•  Always keep the battery cables and terminals clean 

and free of corrosive build-up.

•  After cleaning the battery and terminals, apply a light 

coat of petroleum jelly or grease to both terminals.

•  Always keep the rubber boot positioned over the 

positive terminal to prevent shorting.

IMPORTANT

: If removing the battery for any reason, 

disconnect the NEGATIVE (Black) wire from it’s terminal 
first, followed by the POSITIVE (Red) wire. When 
re-installing the battery, always connect the POSITIVE 
(Red) wire its terminal first, followed by the NEGATIVE 
(Black) wire. Be certain that the wires are connected to 
the correct terminals; reversing them could change the 
polarity and result in damage to your engine’s alternat-
ing system.

Charging

IMPORTANT: 

When charging your tractor’s battery, use 

only a charger designed for 12V lead-acid batteries. 
Read your battery charger’s Owner’s Manual prior to 
charging your tractor’s battery. Always follow its instruc-
tions and heed its warnings.
If your tractor has not been put into use for an extended 
period of time, charge the battery as follows:
Set your battery charger to deliver a maximum of 10 
amperes. If your battery charger is automatic, charge 
the battery until the charger indicates that charging is 
complete.

If the charger is not automatic, charge for no fewer than 
eight hours.

WARNING: 

Batteries give off an explosive 

gas while charging. Charge battery in a 
well ventilated area and keep away from 
an open flame or pilot light as on a water 
heater, space heater, furnace, clothes dryer 
or other gas appliances.

Jump Starting

WARNING: 

When removing or installing the 

battery, follow these instructions to prevent 
the screwdriver from shorting against the 
frame.

IMPORTANT

: Never jump your tractor’s dead battery with 

the battery of a running vehicle.
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

IMPORTANT: 

These failures are NOT covered by your 

tractor’s warranty.

WARNING

Never exceed the 

maximum inflation 

pressure shown on the 

sidewall of the tire.

Batteries give off an 

explosive gas while 

charging. Charge bat-

tery in a well ventilated 

area and keep away 

from an open flame 

or pilot light as on a 

water heater, space 

heater, furnace, clothes 

dryer or other gas 

appliances.
