Troubleshooting, Adjustments, & Service

TRANSMISSION DRIVE BELT REPLACEMENT

1.Park the rider on a smooth, level surface such as a concrete floor. Disengage the PTO, lock the motion control levers into their neutral locked positions, turn off the engine, and remove the ignition key.

2.Remove the mower belt from the PTO pulley (see MOWER BELT REPLACEMENT for instructions).

3.Relieve tension on the transmission belt (A, Figure 33a) by moving the idler arm (E) in the direction indi- cated by the curved arrow, and remove the old belt from the crankshaft and transmission pulleys.

4.Loosen (do not remove) the anti-rotation bracket hardware (C, Figure 33a), and slip the old belt out between the anti-rotation pin (B) and the PTO (A).

Note: The PTO wiring harness must be disconnected from the main wiring harness in order to remove and replace the transmission belt. Be sure to reconnect the harness after the belt is replaced.

5.Reversing steps 3-4, install the new belt, following the routing in Figure 33b. Make sure the V-side of the belt runs in the grooves of the crankshaft pulley and transmission pulleys (B & C). Also, make sure that the anti-rotation pin (B, Figure 33a) is inserted into the anti-rotation slot on the PTO before tightening hardware (C).

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.

Remove the battery from the rider and place on a level, non-concrete surface. Charge the battery at 6-10 amps for 1 hour. Do not charge at a rate higher than 10 amps.

WARNING

Keep open flames and sparks away from the battery; the gasses coming from it are highly explosive. Ventilate the battery well during charging.
