If you are unfamiliar with the oper-
ation of a Zero Turn Mower, READ
the Safety Section and the Controls Section before
Operating.

Training
Zero Turn Mowers are more maneuverable than conven-
tional riding mowers because of the unique steering ca-
pabilities.
Before attempting to operate this Zero Turn Mower under
it’s own power, the Operation Section should be reviewed
entirely.
After reviewing the Operation Section, board the Zero
Turn Mower
(Always from the left side or front only,
never from the right hand side ) . Begin slowly by prac-
ticing on a smooth, hard, level surface such as concrete
or asphalt before moving to turf.
Choose an area where no people, vehicles or other ob-
stacles are present.
Do not move the Steering Levers too aggressively to the
most forward or rearward positions during your initial op-
eration. Moving to turf before being completely comfort-
able with the maneuverability of this Zero Turn Mower
could cause turf damage.
