the Positive terminal (+) of the low charge bat-
tery.
c.

Negative terminal of the charged battery.

to the frame of the unit with the low charge 
battery.

Fuses: There are two fuses located in the wiring 
between the ignition and start switch and other 
electrical components. These are standard plug-
in type automotive fuses rated at 20 and 30 amp.
7.
Safety Switches: There are three safety 
switches in the electrical circuit which control the 
engine. They are (1) the blade clutch switch, (2) 
the steering lever/parking brake switch, and (3) 
the seat switch.They operate so that in order to 
start the engine, the blade clutch switch must be 
off, the parking brake must be engaged, and both 
steering levers must be in the neutral position. 
Once the engine is started, the seat must be 
occupied and the parking brake must be released 
before either of the steering levers can be moved. 
Also, the seat must be occupied before the blade 
clutch switch can cause the blades to rotate.
8.
Safety Switch Operation Checks: The following 
operational checks should be made daily.
a.
Blade Clutch Switch: Sit in the operator’s 
seat. With both steering levers in the neutral 
position and the parking brake engaged, turn 
the blade clutch switch “on” and try to start the 
engine. The engine should not start. If it does, 
the blade clutch switch must be replaced. If 
the engine does not start, turn the blade 
clutch switch “off” and start the engine. Now 
turn the blade clutch switch “on” and the 
blades should rotate. If the blades do not turn, 
the blade clutch switch must be replaced, the 
seat switch must be replaced or the electric 
PTO clutch must be repaired. 
The air-gap should be checked every 100 hrs. 
(or less, if severe operating conditions exist 
such as when there are many on/off cycles, 
mulching operations, material collection sys-
tems used, and dusty/dirty conditions), and 
the air-gap adjusted if more than 0.025". To 
inspect, remove the “negative” cable from the 
battery and all sparkplug wires. The air-gap 
should be checked with feeler gages in the 
three slots of the BBC (PTO Clutch). See 
page 22 for air gap adjustment specs. There 
are three inspection slots in the brake cover. 
To adjust, successively tighten each of the 
three gap adjustment nuts an equal amount. 
Insert a feeler gage (see page 22 for specs) 
into each slot as the air gap adjustment nut 
are tightened. The correct adjustment occurs 
when slight contact with the feeler gage 
occurs. Engage the BBC (PTO Clutch) a cou-
ple of times, and re-check the air-gap. If it is 
not between the specs listed on page 22, 
repeat the adjustment procedure.
b.
Steering lever/Parking Brake Switch: Sit in 
the operator’s seat. With both steering levers 
in the neutral position and the blade clutch 
switch “off”, release the parking brake and try 
to start the engine. The engine should not 
start. If it does, the parking brake switch must 
be repositioned or perhaps replaced. If the 
engine does not start, engage the parking 
brake and start the engine.
c.
Seat Switch: With both steering levers in the 
neutral position, the parking brake engaged 
and the blade clutch switch in the “off” posi-
tion, start the engine. Now release the parking 
brake, hold down on the back of the operator’s 
seat against spring pressure. 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 in the 
neutral position, the parking brake engaged 
and the blade clutch switch in the “off” posi-
tion, 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.
d.
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 trou-
ble free device. If a problem develops and the 
blades do not turn, first check the 20 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 investi-
gate 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.
E.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.
