POSITION
TO USE THROTTLE CONTROL (See Fig. 5)
Always operate engine at full speed (fast).
• Operating engine at less than full speed (fast) reduces
engine's operating effi ciency.
• Full speed (fast) of fers the best mower per for mance.
TO ADJUST MOWER CUTTING HEIGHT
(See Fig. 6)
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 ap prox i mate ly 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.

HOW TO USE YOUR TRACTOR
TO SET PARKING BRAKE (See Fig. 6)
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 brake pedal into full “BRAKE” position and
hold.
• Place parking brake lever in “ENGAGED” position and
re lease pressure from brake pedal. Pedal should re-
main in “BRAKE” position. Make sure parking brake
will hold tractor secure.
STOPPING (See Fig. 6)

• To stop mower blades, push at tach ment clutch lever in
to disengaged position.
GROUND DRIVE -
• To stop ground drive, depress brake pedal all the way
down.

RETURN TO NEUTRAL POSITION WHEN NOT 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 stopping, may cause
engine to “backfi re”.
• Turn ignition key to “STOP” position and remove key.
Always remove key when leaving tractor to prevent
un au tho rized use.
• Never use choke to stop engine.
IMPORTANT: LEAVING THE IGNITION SWITCH IN ANY
POSITION OTHER THAN "STOP" WILL CAUSE THE BATTERY
TO DISCHARGE AND GO DEAD.
NOTE: Under certain conditions when tractor is standing
idle with the engine running, hot engine exhaust gases may
cause “browning” of grass. To elim i nate this possibility, al-
ways stop en gine when stopping tractor on grass areas.
CAUTION: Always stop tractor com-
plete ly, as de
scribed above, before
leav ing the operator's position.
TO MOVE FORWARD AND BACKWARD
The direction and speed of movement is controlled by the
forward and reverse drive pedals.
• Start tractor and release parking brake.
• Slowly depress forward or reverse drive pedal to begin
movement. Ground speed increases the further down
the pedal is depressed.
TO USE CRUISE CONTROL
The cruise control feature can be used for forward travel
only.
SYSTEM CHARACTERISTICS
The cruise control should only be used while mowing or
transporting on relatively smooth, straight surfaces. Other
conditions such as trimming at slow speeds may cause the
cruise control to disengage. Do not use the cruise control
on slopes, rough terrain or while trimming or turning.
• With forward drive pedal depressed to desired speed,
move cruise control lever forward to “SET” position and
hold while lifting your foot off the pedal, then release
the cruise control lever.
• To disengage the cruise control, pull the lever backward
to “OFF” position, or fully depress the brake pedal.
