OPERATION

The operation of any tractor can  result in foreign objects thrown into the eyes, which can 
result in severe eye dam age.  Always wear safety glass es or eye shields while operating 
your tractor or per form ing any adjustments or repairs.  We rec om mend a wide vision safety 
mask over spectacles or stan dard safety glasses.

IMPORTANT:

LEAVING THE IGNITION SWITCH IN ANY 

POSITION OTHER THAN "OFF" WILL CAUSE THE BATTERY 
TO BE DIS CHARGED, (DEAD).

NOTE: 

 Under certain conditions when tractor is standing 

idle with the engine running, hot en gine exhaust gases may 
cause “browning” of grass. To eliminate this possibility, al-
ways stop engine when stopping tractor on grass areas.

CAUTION:  Always stop tractor com-
 plete ly, as described above, before leav-
 ing the operator's position; to empty 
grass catcher, etc.

HOW TO  USE YOUR TRACTOR

TO SET PARKING BRAKE (See Fig. 7)

Your tractor is equipped with an operator presence sens-
 ing  switch.  When engine is running, any attempt by the 
op er a tor to leave the seat without fi rst setting the parking 
brake will shut off the engine.
•      Depress clutch/brake pedal into full “BRAKE” position 

and hold.

•      Place parking brake lever  in “ENGAGED” position and 

re lease pressure from clutch/brake pedal.  Pedal should 
re main in “BRAKE” position.  Make sure parking brake 
will hold tractor secure.

STOPPING (See Fig. 7)

MOWER BLADES -
•     To stop mower blades,move attachment clutch lever 

to “DIS EN GAGED” po si tion.

GROUND DRIVE -
•      To stop ground drive, depress clutch/brake pedal into 

full “BRAKE” position.

•      Move motion control lever to neutral (N) position.

IMPORTANT:

THE MOTION CONTROL LEVER DOES NOT 

RETURN TO NEUTRAL (N) POSITION WHEN THE CLUTCH/
BRAKE PEDAL IS DEPRESSED.

ENGINE -

 

•      Move throttle control between half and full speed (fast) 

position.

NOTE:

  Failure to move throttle control between half and 

full speed (fast) position, before stop ping may cause engine 
to “backfi re”.
•     Turn ignition key to “OFF” position and remove key.  

Always remove key when leaving tractor to prevent 
un author ized use.

•      Never use choke to stop engine.

TO MOVE FORWARD AND BACKWARD  
(See Fig. 7)

The direction and speed of movement is controlled by the 
motion control lever.
•     Start tractor with motion control lever in neutral (N)  

position.

•      Release parking brake.
•      Slowly move motion control lever to desired position. 

 TO USE THROTTLE CONTROL (See Fig. 7)

Always operate engine at full throttle.
•      Operating engine at less than full throttle reduces the 

battery charging rate.

•      Full throttle of fers the best bagging and mower per for -

mance.

TO ADJUST MOWER CUTTING HEIGHT  
(See Fig. 7)

The cutting height is controlled by turning the height ad-
 just ment knob in desired direction.
•      Turn knob clockwise (

 ) to raise cutting height.

•      Turn    knob    counterclockwise  ( 

) to  lower cutting 

height.

The cutting height range is approximately 1-1/2" to 4".  The 
heights are measured from the ground to the blade tip with 
the engine not running.  These heights are ap proxi mate and 
may vary depending upon soil conditions, height of grass 
and types of grass being mowed.
•         The average lawn should be cut to approximately 2-1/2  

inches during the cool season and to over 3 inches 
during hot months.  For healthier and better looking 
lawns, mow often and after moderate growth.

•     For best cutting performance, grass over 6 inches 

in height should be mowed twice.  Make the fi rst cut 
relatively high; the sec ond to desired height.
