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.
f. Folding Deck Position Switches: There
are switches located on the folding deck
mechanism of each folding section, both
switches must be depressed to activate the
electric PTO clutch (BBC).
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; 10-12 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
