Throttle / Choke Control

The throttle control lever is located on the left side 

of the tractor’s dash panel, see Figure 4-1. 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 tractor with the 

cutting deck engaged, be certain that the throttle 

lever is always in the FAST (rabbit) position.
Moving the throttle 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 in the Operation 

section of this manual for detailed starting 

instructions.

Ignition Switch

The ignition switch is activated to start the engine. 

Insert key into the ignition switch and turn clockwise to the 

START position. Release the key into the ON position once engine 

has fired. See Figure 4-2.

WARNING! 

Never leave a running machine 

unattended. Always disengage PTO, move shift lever 

into neutral position, set parking brake, stop engine 

and remove key to prevent unintended starting.

IMPORTANT: 

Prior to operating the tractor, refer to both Safety 

Interlock Switches and Starting The Engine in the Operation section 

of this manual for detailed instructions regarding the Ignition Switch 

Module.

Clutch-Brake Pedal

The clutch-brake pedal is located on the left side of the lawn 

tractor, along the running board. Depress the clutch-brake pedal 

part way down when slowing the tractor by changing speeds

 

(Refer to Speed Control Lever)

. Depress the pedal all the way down 

to engage the disc brake and bring the tractor to a complete stop.

NOTE: 

The clutch-brake pedal must be depressed to start the 

engine. Refer to Safety Interlock Switches in the Operation 

section of this manual.

Shift Lever 

The shift lever is located on the left side of the fender and has 

three positions, FORWARD, NEUTRAL and REVERSE. The brake 

pedal must be depressed and the tractor 

must not be in motion 

when moving the shift lever. See Figure 4-3.

IMPORTANT: 

Never force the shift lever. Doing so may result in 

serious damage to the tractor’s transmission.

Figure 4-3

Speed Control Lever

The speed control lever, located on the lower left 

side of the 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 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 tractor’s ground speed, depress the 

clutch-brake pedal and move the speed control 

lever rearward and release it into a notch.
