Ignition Switch

 

The ignition switch has three positions, Off, 

Run and Start. The key will turn to Start and 

move back to Run upon release. Turning the 

key to the Off position will stop the engine; 

however, always remove the key when 

leaving the machine to prevent someone from 

accidentally starting the engine (

Figure 5

). 

Blade Control Switch (Power Take-Off)

 

The blade control switch, represented by a 

power take-off (PTO) symbol, engages and 

disengages power to the mower blades 

(

Figure 5

). 

Choke Control

 

The choke is used to aid in starting a cold 

engine.  

DO NOT

 run a warm engine with the 

choke in the 

“ON”

 position.  Moving the 

choke lever forward will put the choke in the 

“ON”

 position and moving the choke lever to 

the rear will put the choke in the 

“OFF”

 

position (

Figure 5

). 

 

 

Throttle Control

 

The throttle is used to control engine speed.  

Moving throttle lever 

forward

 will increase 

engine speed and moving throttle lever 

to the 

rear

 will decrease engine speed.  Moving the 

throttle forward into the detent is full throttle 

(

Figure 5

). 

Motion Control Levers and Parking 

Brake

 

The motion control levers are speed sensitive 

controls of independent wheel motors.  Moving 

a lever forward or backward turns the wheel on 

the same side forward or in reverse; wheel 

speed is proportional to the amount the lever is 

moved.  Moving the control levers outward from 

the center position locks them in the neutral 

position.  Engaging the parking brake lever 

allows the operator to exit the machine     

(

Figure 13

).  Always position the motion control 

levers into the neutral position and engage the 

park brake lever when you stop the machine or 

leave it unattended. 

Height-of-Cut Foot Lever

 

The height of cut lever allows the operator to 

lower and raise the deck from the seated 

position. When the lever is moved forward, 

away from the operator the deck is raised from 

the ground and when moved back, towards the 

operator it is lowered toward the ground. Only 

adjust the height of cut while machine is not 

moving (

Figure 14

).
