e.Electric PTO Clutch: This clutch operates when the engine is running, the operator is in the operator’s seat and the blade clutch switch is turned on.This electric clutch is a fairly trouble free device. If a problem develops and the blades do not turn, first check the 7.5 amp fuse in the yel- low, 16-gauge wire between terminal “L” (for the Gasoline Engine) on the ignition switch and the hour meter and then investigate the wiring harness and the connections to the seat switch, the blade clutch switch and the electric blade clutch. Then check out the seat switch, the blade clutch switch and finally the electric blade clutch.

D.Tires

The two front wheels are caster wheels that are free to swivel to accommodate the direction of the mower.

The two rear wheels are used to propel the mower in the direction of input from the drive handles. Inflation pressure of the rear tires is important for stability while the mower is in operation. If the tire diameter is not equal between the two tires, the mower will pull to one side.

1.Inflation Pressure:

a.Traction Tires—20 psi max; 8-10 psi recommended

b.Front Caster Wheel—40 psi max; 25-30 psi recommended

c.Cutting Deck Ball Wheels—Solid Polypropylene.

Use the Following guidelines for maintaining the tires:

a.Balance inflation pressure between the rear tires to help maintain straight travel (see tire side wall for proper inflation pressure).

b.Keep the valve caps tightened to prevent air pressure loss.

2.Leaking Tires: When a flat tire occurs, repair or replace immedi- ately. The normal procedure is to remove the wheel and replace it with a spare. Take the leaking tire to a maintenance area and repair. If a tire is getting soft, park the mower on the nearest level, paved area. If the leaking tire is on a traction wheel, put blocks on each side of the opposite traction wheel and jack up the tire that leaks about an inch off the ground. Loosen and remove the lug nuts and remove the wheel. Mount a spare wheel and tire, replace the lug nuts, and using a torque wrench, tighten them to 60 ± 10 lb- ft.

If the leaking tire is on a front caster wheel, block both traction wheels and raise the caster wheel so that the tire is an inch off the
