the traction surface and the tire. If the lap 
bar on the turn side is not brought all the 
way to neutral, then the turn side tire will 
continue to rotate and a “U-turn” will be 
executed with a low potential for turf 
defacement as well as traction surface 
and tire damage.

i.

To drive in the REVERSE direction:

1.

Make sure no bystanders, animals, or 

objects are behind the machine. Look 
behind the machine, and use extreme 
care.

2.

Slowly, move both lap bars toward the 

rear of the machine until the machine 
begins to move rearward. Release the 
lap bars and the machine should stop. 
The more the lap bars are moved toward 
the rear of the machine, the faster the 
machine will move in the reverse direc-
tion. Release the lap bars and the 
machine should stop traveling in reverse 
(this is a safety check, the normal proce-
dure is for the operator to slowly bring 
the lap bars to the neutral position).

3.

Do not retard the lap bars rapidly as this 

could cause turf defacement and/or loss 
of traction.

4.

To turn, retard one lap bar ahead of the 

other and the machine will turn toward 
the same side that was retarded — I.E., 
to turn counter-clockwise (to the LEFT), 
move the LEFT lap bar rearward more 
than the right side, and to turn clockwise 
(to the RIGHT), move the RIGHT lap bar 
rearward more than the left side. NOTE: 
If one lap bar is in the neutral position 
and the other is retarded, the turn side 
tire will not rotate and a “pivot turn” will 
be executed. Turf defacement could 
occur (if on grass) as well as potential 
damages to the traction surface and the 
tire. If the lap bar on the turn side is not 
brought all the way to neutral, then the 
turn side tire will continue to rotate and a 
“U-turn” will be executed with a low 
potential for turf defacement as well as 
traction surface and tire damage.

j.

To perform a “zero turn”:

1. Please note, a zero turn maneuver can 

not be executed while the machine is 
moving in the Forward or, Reverse direc-
tions, the machine must come to a stop 
first.

2. To turn clockwise, slowly move the LEFT 

lap bar forward while simultaneously 
moving the RIGHT lap bar rearward. 

Release both lap bars and the machine 
should stop turning.

3. To turn counter-clockwise, slowly move 

the RIGHT lap bar forward while simulta-
neously moving the LEFT lap bar rear-
ward. Release both lap bars and the 
machine should stop turning (this is a 
safety check, the normal procedure is for 
the operator to slowly bring the lap bars 
to the neutral position).

3.

Start the Engine:

a.

Open the fuel shutoff valve.

b.

Sit on the Seat. Set the parking brake 
“On”.

c.

Make sure the left and right steering levers 
are in the neutral position.

d.

Turn the electric blade clutch switch “Off”.

e.

Push the throttle control to a position a 
third of the way between slow and fast.

f.

Insert the key in the ignition and start 
switch and turn the switch to “On”.

g.

Gasoline Engine: If the engine is cold, 
push the choke to the on position.

h.

Turn the ignition key in a clockwise direc-
tion to the “Start” position until the engine 
starts.

Note:

 

Do not hold the key in the “Start” 

position for more than 10 seconds or you may 
damage the starter. If the engine does not start 
in this time, wait about 30 seconds and try 
again.

i.

Gasoline Engine: Once the engine starts, 
push the choke on halfway and as the 
engine warms, push the choke off all the 
way.

4.

Operating the Mower:

 Operating a zero-turn-

ing-radius mower is not like operating a trac-
tor-type riding mower. The zero-turning-radius 
mower is much more maneuverable and 
much less fatiguing to operate. However, get-
ting used to the fingertip control of the zero-
turning-radius mower takes some practice. 
We strongly recommend that you locate a 
“test area” where you can operate the mower 
for about 30 minutes without being disturbed.

a. Get into the operator’s seat.
b.

Start the engine.

c.

Use the transport lever to raise the mowing 

deck to the transport position. Make sure 
the blade clutch switch is off.

d. After the engine has warmed, adjust the 

throttle to the fast position.

e. Release the parking brake.
