parking brake engaged and the blade 
clutch switch in the “off” position, start the 
engine. Now release the parking brake, 
hold down on the back of the operator’s 
seat against spring pressure, and swing 
one of the steering levers up to the operat-
ing position. Release the operator’s seat 
and the engine should stop. If the engine 
does not stop, the seat switch must be 
replaced. With both steering levers folded 
out in the neutral position, the parking 
brake engaged and the blade clutch switch 
in the “off” position, sit in the operator’s 
seat and start the engine. Turn the blade 
clutch switch to the “on” position and the 
blades should start to rotate. Raise up 
slightly off the operator’s seat and the 
blades should stop. If the blades do not 
stop when you dismount from the opera-
tor’s seat, the seat switch must be 
replaced.

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 yellow, 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 rec-

ommended

b.

Front Caster Wheel—28 psi max; 20-25 

psi recommended

c.

Cutting Deck Ball Wheels—Solid Polyure-

thane.

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 pres-
sure).

b.

Keep the valve caps tightened to prevent 
air pressure loss.

2.

Leaking Tires: When a flat tire occurs, repair 
or replace immediately. 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 ft-lbs.

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
ground. Loosen and remove the locknut from
the axle assembly and pull the axle assembly
from the caster yoke. The wheel and two
spacer sleeves will drop free. Slip the axle
assembly through one side of the caster
yoke, through a spacer sleeve, a spare wheel,
the other spacer sleeve and finally through
the other side of the caster yoke. Then
tighten the locknut on the end of the axle
assembly.

Lower the mower off the jack and continue
mowing. The wheel with the leaking tire
should be taken to the maintenance area, the
tire inflated to 20 psi and the wheel placed in
a large bucket of water. Carefully inspect the
tire, rim and valve for escaping air bubbles
which indicate a leak. Mark each leak with a
yellow marking crayon and then deflate the
tire to 8 psi and repeat the inspection. If the
leaks you find are pin hole size to 1/16"
diameter, the tire can be repaired using an
aerosol can of tire inflater and latex sealer
available from any auto supply store. Follow
the directions on the can. If the leaks are
larger than 1/16" diameter, the tire can be
repaired with rubber plugs also available in a
kit from any auto supply store. If the tire bead
is damaged, a tube will have to be installed in
the tire or the tire will have to be replaced.

3.

Creeping: Creeping is the slight forward or 
backward movement of the mower when the 
throttle is on and the lapbars are in the
