Throttle/Choke Control Lever
The throttle/choke control lever is
located on the left side of the lawn
tractor’s dash panel. This lever controls
the speed of the engine, as well as the
choke when it is pushed all the way
forward. When set in a given position,
the throttle will maintain a uniform
engine speed.
Important: When operating the lawn
tractor with the cutting deck engaged,
be certain that the throttle/choke
control lever is always in the FAST
(rabbit) position.
Moving the throttle/choke control
lever all the way forward activates the
engine’s choke control. Activating the
choke control closes the choke plate on
the carburetor and aids in starting the
engine.
Refer to Starting the engine on page
12 for detailed starting instructions.
Speed Control Lever
Hydrostatic
The speed control lever,
located on the left rear
fender, controls the ground
speed of the lawn tractor as
well as the direction of travel.
To drive forward or in reverse,
slowly move the speed
control lever to the desired
“F” forward or “R” reverse
speed.
To stop, move the speed
control lever to the “N
neutral position.
When mowing, place the speed control lever in the
“Cutting Speed” position, or a slower forward speed
for the best results.
Note: Do not use the parking brake pedal to control
the ground speed of the lawn tractor. Always use the
speed control lever to slow the ground speed of the
lawn tractor. Depressing the parking brake pedal with
the speed control lever engaged as part of regular
operation will result in premature wear of the drive
belt.
Important: Do not attempt to change the direction
of travel when the lawn tractor is in motion. Serious
damage to the lawn tractor’s transmission could result.
Always bring the lawn tractor to a complete stop before
moving the speed control lever from forward to reverse
or vice versa.
CVT
The speed control lever, located on the
lower left side of the lawn tractor’s dash
console, allows you to regulate the ground
speed of the lawn tractor.
To use, depress the clutch-brake pedal and
move the lever out of the parking brake
notch and forward to increase the lawn
tractor’s ground speed. When a desired
speed has been reached, release the lever
into an appropriate notch to maintain that
speed.
To slow the lawn tractor’s ground speed,
depress the clutch-brake pedal and move
the speed control lever rearward and
release it into a notch.

Hydrostatic & Foot Control CVT
The parking brake pedal is located on the
left side running board of the lawn tractor. It
is used to set the parking brake and to stop
the lawn tractor in sudden situations. The
