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
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
