SECTION 10D. BATTERY
GENERAL
For normal service, use a battery rated 12V, 450 cold
cranking amps at 0°F (-18°C) Group BCI26.
CHARGING A MAINTENANCE FREE
BATTERY
1. Be sure the charger is “OFF.”
2. Connect the charger leads to the battery. Connect
the positive (+ POS) connector from the charger to
the positive battery terminal. Connect the negative
(- NEG) connector of the charger to the negative
battery terminal.
3. Charge the battery using one of the methods
shown below. Follow the manufacturer’s instruc-
tions on the charger.
4. Always turn the charger to “OFF” before removing
a charge lead from the battery.
MAINTENANCE/CLEANING
A buildup of corrosive acid across the top of the battery
can cause the battery to self-discharge. Even a light
coating of this grayish-white substance can cause a cir-
cuit to drain and exhaust the energy in the battery. This
is especially bad when moisture is present.
To maintain a battery in top condition, check and per-
form the following services at frequent intervals.
1. Regularly check the level of electrolytes and add
water as necessary to maintain a level above the
plates. Do not overfill the battery as this can cause
poor performance or early failure due to loss of
electrolytes.
WARNING
Batteries contain sulfuric acid and can generate
explosive mixtures of hydrogen and oxygen gases.
Keep any device that may cause sparks or flames
away from the battery to prevent explosion.
WARNING
Always wear protective glasses or goggles and pro-
tective clothing when working with batteries.
You must follow the battery manufacturer’s instruc-
tions on safety, maintenance, and installation proce-
dures.
WARNING
Always connect the ground (black) cable last and
remove it first when performing any battery mainte-
nance. When the battery is being removed or rein-
stalled, make sure the positive and negative
terminals do not contact metal tractor parts at the
same time or arcing will result. Battery connections
must be kept clean and tight at all times. Loose
cables will cause arcing and pitting of the connec-
tions and eventual failure. Keep the positive terminal
cover in place.
NOTICE
Remove the battery from the tractor before you
begin charging.
WARNING
To avoid possible injury, stand away from the battery
when the charger is turned on. A damaged battery or
a battery with an internal short could explode.
Slow Charge Fast Charge

CAUTION
If, when charging the battery, violent gassing or
spewing of electrolytes occurs, or the battery case
feels hot (125°F (52°C)), reduce or temporarily halt
charging to avoid damaging the battery.
