run. Turn off the PTO by pushing the 
control switch down.

h.

To drive in the FORWARD direction:

1.

Set the engine speed to 2000 to 2500 
rpm (refer to tachometer on right control 
panel). This must be increased to full 
speed (3525-3675 rpm) after becoming 
familiar with the machine.

2.

Release the park brake.

3.

Move both lap bars out of the neutral/
start position to the neutral position 
(toward center of machine). Slowly, move 
both lap bars toward the front of the 
machine until the machine begins to 
move forward — release the lap bars 
and the machine should stop. The more 
that the lap bars are moved toward the 
front of the machine, the faster the 
machine will move in the forward direc-
tion. Release the lap bars and the 
machine should stop traveling forward. 
(This is a safety check, the normal pro-
cedure is for the operator to slowly bring 
the lap bars to the neutral position).

4.

Do not advance the lap bars rapidly as 
this could cause turf defacement, loss of 
traction, and/or instability.

5.

To turn, advance one lap bar ahead of 
the other and the machine will turn 
toward the opposite from the side that 
was advanced — I.E. to turn clockwise 
(to the Right), move the LEFT lap bar for-
ward more than the right side, and to 
turn counter-clockwise (to the LEFT), 
move the RIGHT lap bar forward more 
than the left side. NOTE: If one lap bar is 
in the neutral position and the other is 
advanced, 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.

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.

Move the left and right steering levers to 
the neutral, opened-out position.

d.

Turn the electric blade clutch switch “Off”.
