Electrical system
The electrical system is a 12-volt, negative ground. Recommended
battery size is a garden tractor BCI group U1R with 225 or better cranking
AMP rating. A maintenance-free battery is recommended. Otherwise,
follow battery manufacturer’s maintenance, safety, storing and charging
specifications.
WARNING: Battery posts, terminals, and related
accessories contain lead and lead compounds, chemicals
known to the State of California to cause cancer and
reproductive harm. Wash hands after handling.
WARNING: Charge batteries in an open well ventilated
area, away from sparks and flames. Unplug charger before
connecting or disconnecting from battery. Wear protective
clothing and use insulated tools.
WARNING: Avoid skin and clothing contact with battery
acid.
Always wear eye protection when checking the battery, acid
can cause serious injury to skin and eyes. If contact occurs,
flush area with clean water and call physician immediately.
Acid will also damage clothing.
Do not drink the battery electrolyte.
Do not allow open flame near the battery when charging.
Hydrogen gas forms inside the battery. This gas is both toxic
and flammable and may cause an explosion if exposed to
flame. Always remove the negative ground first and replace
it last.
Do not overfill battery.
Electrolyte may overflow and damage paint, wiring or
structure. When cleaning the battery, use soap and water. Be
careful not to get soap and water into the battery. Clean the
battery terminals with a solution of four parts water and one
part baking soda when they become corroded.
WARNING: Shorts caused by battery terminals or metal
tools touching metal tractor components can cause sparks.
Sparks can cause a battery gas explosion which will result in
personal injury.
Prevent the battery terminals from touching any metal tractor
parts when removing or installing the battery.
Do not allow metal tools to short between the battery
terminals and metal tractor parts.
WARNING: Incorrect battery cable routing could cause
damage to the tractor and battery cables. This can cause
sparks which can cause a battery gas explosion which will
result in personal injury.
Always disconnect the negative (black) battery cable(s)
before disconnecting the positive (red) cable(s).
Always connect the positive (red) battery cable(s) before
disconnecting the negative (black) cable(s).

the operator’s platform. Fig. 4-2
Check oil level in hydraulic system after every 50 hours of operation or
weekly, whichever occurs first. Check more often if system appears to be
leaking or otherwise malfunctioning.
