HYDRAULIC PUMP DRIVE BELT
REPLACEMENT
1. Park the rider on a smooth, level surface such as a
concrete floor. Disengage the PTO, engage the park-
ing brake, turn off the engine, and remove the ignition
key.
2. Remove the PTO drive belt (see MOWER BELT
REPLACEMENT for removal instructions).
3. Loosen the nut towards the front of the machine on
the spring anchor hook (H, Figure 32) to release the
majority of the belt tension. Use caution and remove
the nut to completely release the tension.
4. Remove the old belt and replace it with the new one.
Make sure the V-side of the belt runs in the grooves
of the crankshaft pulley and pump pulleys (B & C).
5. Reinstall the anchor hook (H) into the anchor tab and
loosely fasten the nut. Adjust the spring until a meas-
urement of 7-3/4" (19,7cm) is achieved from the out-
side of the spring hooks. Tighten nut.
6. Reinstall the PTO drive belt.

BATTERY CHARGING

A dead battery or one too weak to start the engine may
be the result of a defect in the charging system or other
electrical component. If there is any doubt about the
cause of the problem, see your dealer. If you need to
replace the battery, follow the steps under Cleaning the
Battery & Cables in the Regular Maintenance Section.
To charge the battery, follow the instructions provided by
the battery charger manufacturer as well as all warnings
included in the safety rules sections of this book. Charge
the battery until fully charged (until the specific gravity of
the electrolyte is 1.250 or higher and the electrolyte tem-
perature is at least 60° F). Do not charge at a rate higher
than 10 amps.
