Craftsman 917.273220 Owner's Manual page 14

The operation of any tractor can result in foreign objects thrown into
the eyes, which can result in severe eye damage. Always wear safety
glasses or eye shields while operating your tractor or performing any
adjustments or repairs. We recommend a wide vision safety mask
over spectacles or standard safety glasses.
HOW TO USE YOUR TRACTOR
TO SET PARKING BRAKE
Your tractor is equipped with an operator
presence sensing switch. When engine
is running, any attempt by the operator to
leave the seat without first setting the
parking brake will shut off the engine.
• Depress clutch/brake pedal into full
"BRAKE" position and hold.
• Place parking brake lever in "EN-
GAGED" position and release pres-
sure from clutch/brake pedal. Pedal
should remain in "BRAKE" position.
Make sure parking brake will hold
tractor secure.

MOWER BLADES -
• To stop mower blades,move attach-
ment clutch lever to "DISENGAGED"
position.
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 de-
pressed.
ENGINE -
• Move throttle control to slow position.
NOTE: Failure to move throttle control to
slow position and allowing engine to
idle before stopping may cause engine
to "backfire".
• Turn ignition key to "OFF" position and
remove key. Always remove key
when leaving tractor to prevent
unauthorized use.
• Never use choke to stop engine.
IMPORTANT: Leaving the ignition
switch in any position other than "OFF"
will cause the battery to be discharged,
(dead).
NOTE: Under certain conditions when
tractor is standing idle with the engine
running, hot engine exhaust gases may
cause "browning" of grass. To eliminate
this possibility, always stop engine when
stopping tractor on grass areas.
CAUTION: Always stop tractor
completely, as described above, before
leaving the operator's position; to empty
grass catcher, etc.
TO USE THROTTLE CONTROL
Always operate engine at full throttle.
• Operating engine at less than full
throttle reduces the battery charging
rate.
• Full throttle offers the best bagging
and mower performance.
TO USE CHOKE CONTROL
Use choke control whenever you are
starting a cold engine. Do not use to start
a warm engine.
• To engage choke control, pull knob
out. Slowly push knob in to disen-
gage.
TO MOVE FORWARD AND
BACKWARD
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 and clutch/
brake pedal.
• Slowly move motion control lever to
desired position.
TO ADJUST MOWER CUTTING
HEIGHT
The cutting height is controlled by
turning the height adjustment knob in
desired direction.
• Turn knob clockwise ( ) to raise
cutting height.
• Turn knob counterclockwise (
lower cutting height.
