BATTERY
The CM mower is equipped with a BCI group
35, 12-bolt battery with a minimum cold
cranking ability of 490 amps at-18°C (0°F)
Make sure the battery connections are tight and
free of corrosion. A solution of baking soda and
water may be used to wash the outside surface
and terminals of the battery when necessary.
However, make sure the solution does not get
inside the battery. After cleaning, wash the
battery with clean water, then apply a small
amount of petroleum jelly to the terminals to
prevent corrosion.
In freezing temperatures, a good battery charge
must be maintained. If the battery becomes
discharged or run down, the electrolyte
becomes weak and may freeze, causing
damage to the case. If you must add water, use
distilled water. Add the water just before using
the tractor so that the water will mix with the
electrolyte during the charging process, thus
preventing the water from freezing.
To determine the battery charge, check the
specific gravity of the electrolyte.
Checking the Electrolyte Level
NOTE: Check the battery electrolyte level
after every 50 hours of operation.
WARNING: ALWAYS CHECK THE
ELECTROLYTE LEVEL WITH THE MOWER
ENGINE OFF, AS AN EXPLOSIVE GAS IS
PRODUCED INSIDE THE BATTERY WHEN
THE ALTERNATOR IS CHARGING. DO NOT
USE AN EXPOSED FLAME AND DO NOT
SMOKE WHEN CHECKING THE BATTERY
ELECTROLYTE LEVEL.
To check the battery electrolyte level:
1. Clean the top of the battery, then remove the
vent plugs.
2. Add distilled water if the electrolyte level is
low. The level is correct when the liquid is
6.35 mm (1/4”) above the plates.
NOTE: Keep distilled water in a
nonmetallic container that is clean and
well-covered.
3. Install the vent plug after making sure the
vent holes are not blocked. At below freezing
temperatures, run the engine for a period of
time after adding water, allowing the battery
to charge, which prevents the water form
freezing.
