TO ADJUST MOWER CUTTING HEIGHT
(See Fig. 16)
The position of the attachment lift lever determines the
cutting height.
• Grasp lift lever.
• Press plunger with thumb and move lever to desired
position.
The cutting height range is approximately 1-1/2 to 4" (38,1
to 101,6 mm). The heights are measured from the ground
to the blade tip with the engine not running. These heights
are approximate and may vary depending upon soil condi-
tions, height of grass and types of grass being mowed.
• The average lawn should be cut to approximately
2-1/2" (63,5 mm) during the cool season and to over 3"
(76,2 mm) during hot months. For healthier and better
looking lawns, mow often and after moderate growth.
• For best cutting performance, grass over 6" (152,4 mm)
in height should be mowed twice. Make the first cut
relatively high; the second to desired height.
TO OPERATE MOWER (See Fig. 16)
Your tractor is equipped with an operator presence sens-
ing switch. Any attempt by the operator to leave the seat
with the engine running and the attachment clutch engaged
will shut off the engine. You must remain fully and centrally
positioned in the seat to prevent the engine from hesitating
or cutting off when operating your equipment on rough,
rolling terrain or hills.
• Select desired height of cut. (See "TO ADJUST MOWER
CUTTING HEIGHT".)
• Start mower blades by engaging attachment clutch
control.
TO STOP MOWER BLADES (See Fig. 16)
Disengage attachment clutch con trol.
CAUTION: Do not operate the mower without
either the en tire grass catcher, on mowers
so equipped, or the deflector chute in place.

REVERSE OPERATION SYSTEM (ROS)
Your tractor is equipped with a Reverse Operation System
(ROS). Any attempt by the operator to travel in the reverse
direction with the attachment clutch engaged will shut off
the engine unless ignition key is placed in the ROS "ON"
position.
WARNING: Backing up with the attachment clutch en-
gaged while mowing is strongly discouraged. Turning the
ROS "ON", to allow reverse operation with the attachment
clutch engaged, should only be done when the operator
decides it is necessary to reposition the machine with the
attachment engaged. Do not mow in reverse unless
absolutely necessary.
USING THE REVERSE OPERATION SYSTEM (See Fig. 17)
Only use if you are certain no children or other bystanders
will enter the mowing area.
• Move motion control lever to neutral (N) position.
• With engine running, turn ignition key counterclockwise
to ROS "ON" position.
• Look down and behind before and while backing.
• Slowly move motion control lever to reverse (R) po si-
tion to start movement.
• When use of the ROS is no longer needed, turn the
ignition key clockwise to engine "ON" position.
ROS "ON"
POSITION
TO OPERATE ON HILLS
CAUTION: Do not drive up or down hills
with slopes greater than 15° and do not
drive across any slope.
• Choose the slowest speed before starting up or down
hills.
• Avoid stopping or changing speed on hills.
• If slowing is necessary, move throttle control lever to
slower position.
• If stopping is absolutely necessary, push clutch/brake
pedal quickly to brake position and engage parking brake.
• Move motion control lever to neutral position.
IMPORTANT: THE MOTION CONTROL LEVER DOES NOT
RETURN TO NEUTRAL POSITION WHEN THE BRAKE PED AL
IS DEPRESSED.
• To restart movement, slowly release parking brake and
clutch/brake pedal.
• Slowly move motion control lever to slowest setting.
• Make all turns slowly.
