Safety During Operation
● Operate the mower only in daylight or in
good articial light with good visibility of the
area being mowed.
● Sit on the seat when starting the engine
and operating the machine. Keep feet on
the deck footrests at all times when the tractor
is moving and/or mower blades are operating.
● Never operate the tractor without a deck or
imple ment installed.
● For a beginning operator, learn to steer
(maneuver) the tractor with a slow engine
speed before attempting any mowing oper-
ation. Be aware that, with the front mounted
mower conguration, the back of the tractor
swings to the outside during turns.
● For an emergency stop: remember the
forward motion of the tractor can always be
stopped by pulling the Forward Speed Control
(FSC) into the NEUTRAL-PARK position.
NOTE: The emergency stop procedure is
exactly the same procedure used to normally
stop and park the machine.
● In the event that you lose control of the
machine (such as the transmission drive belt
breaks during operation, and the machine
starts to freewheel down a slope), you can
maintain control by immediately (1) Releas-
ing the steering levers and simultaneously (2)
Moving the FSC to the NEUTRAL-PARK posi-
tion. When the machine is stopped or moving
slowly, engage the parking brake.
