SETTING THE CUTTING HEIGHT

Select the height position of the cutting deck by
placing the deck lift lever in any of the six different
cutting height notches on the right side of the fender.
Then adjust the deck wheels so that they are at least
1/4 inch to 1/2 inch above the ground when the
tractor is on a smooth, flat surface such as a
driveway.
WARNING:
from the discharge chute opening of the
cutting deck.
NOTE:
The deck wheels are an anti-scalp feature
of the deck and are not designed to support the
weight of the cutting deck.
Refer to the ADJUSTMENTS section of this manual
for more detailed instructions regarding various deck
adjustments.

STARTING THE ENGINE

NOTE:
Refer to the TRACTOR SET-UP section of
this manual for Gasoline and Oil fill-up instructions.
• Insert the tractor key into the ignition switch.
• Place the PTO lever, or PTO knob in the
disengaged (OFF) position.
• Depress the brake pedal and set the parking
brake.
• Place the shift lever in the NEUTRAL position.
• Move the throttle control lever into the FAST
(or CHOKE, if so equipped) position.
• Pull out the choke control knob, if so equipped
(a warm engine may not require choking).
• Turn the ignition key clockwise to the START
position. After the engine starts, release the
key. It will return to the ON position.
IMPORTANT:
Do NOT hold the key in the START
position for longer than ten seconds at a time. Doing
so may cause damage to your engine's starter.
NOTE:
If starting problems are encountered, refer
to the TROUBLESHOOTING section of this manual.
After the engine starts, slowly release the brake
pedal. As the engine warms up, gradually push the
choke control knob inward (or move the throttle
control lever out of the CHOKE position into the
FAST position) to open up the choke plate on the
engine's carburetor.
NOTE:
Do NOT leave the choke control out while
operating the tractor. Doing so will result in a "rich"
fuel mixture and cause the engine to run poorly.
Keep hands and feet away

STOPPING THE ENGINE

• Place the PTO lever, or PTO knob in the
disengaged (OFF) position

OFF position.

prevent accidental starting.
