ing rope  as soon as engine starts. To stop engine turn key

5. Set engine to desired speed by adjusting throttle control. 

(Suggest set at slow speed during initial operation.)

 

6. NOTE SAFETY FEATURE: Engine stops automatically if

7. This unit is equipped with a unique transaxle that requires 

only two drive levers to control braking, turning, direction 

and acceleration. TO GO FORWARD:

 

From neutral position push both drive levers slightly for-

ward; to increase speed move levers further forward. TO 

GO BACKWARD:

 

From neutral position pull both drive levers slightly 

rearward. TURNING:

 

Turning is controlled by moving one drive lever slightly 

forward or rearward of the other. To turn left, move left 

lever rearward of right lever. To turn "square corners" move 

lever of desired direction to neutral. To turn on  mower's 

own axis (Zero radius) reduce speed and move one lever to 

reverse position and the other to forward position.

 

BRAKING:

 

To brake mower, move both levers in direction opposite of 

travel, release levers to neutral, set parking brake. When 

stopping on incline, it may be necessary to hold slight 

pressure on levers in direction opposite of slope, until 

parking brake is set.

 

ALWAYS SET PARKING.BRAKE BEFORE DISMOUNTING.

 

INITIAL OPERATION:

 

It is recommended that first operation of mower be done at 

a slow setting of throttle speed and disengagement of 

mower blades until operator is thoroughly familiar with  the 

unit.

 

You may have tendency to "over control" mower at first. 

Slight movements — fingertip control — is all that's 

necessary for easy operation. 8. Mower Blade Operation:

 

• Cutting height is set by positioning the adjustment lever. 

Push button knob on top of lever, set desired cutting 

height, lock into position by releasing button knob.

 

• To start mower blades, move lever on floor to "engage" 

position. To stop mower blades, move lever to "disen-

gage" position.
