REVERSE OPERATION SYSTEM (ROS)
(See Fig. 11)
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
Only use if you are certain no children or other bystanders
will enter the mowing area.
• Depress brake pedal all the way down.
• With engine running, turn ignition key counterclockwise
to ROS "ON" position.
• Look down and behind before and while backing.
• Slowly depress reverse drive pedal to start movement.
• When use of the ROS is no longer needed, turn the
ignition key clockwise to engine "ON" position.

• If stopping is absolutely necessary, push brake pedal
quickly to brake position and engage parking brake.

ting.

TO TRANSPORT (See Fig. 3 & 12)
When push ing or tow ing your trac tor, ensure transmission
is disengaged by placing freewheel control in free wheel ing
po si tion. Free wheel control is located at the rear drawbar
of tractor.
• Raise attachment lift to highest position with at tach ment
lift control.
• Pull freewheel control out until the free wheel control
rod locks in extended position.
• Do not push or tow tractor at more than two (2) mph
(3,2 km/h).
• To reengage transmission, reverse above procedure.
NOTE: Freewheel control will automatically disengage
when the brake/clutch pedal is depressed.

NOTE: To protect hood from damage when transporting
your tractor on a truck or a trailer, ensure hood is closed
and secured to tractor. Use an appropriate means of tying
hood to tractor (rope, cord, etc.).
TOWING CARTS AND OTHER AT TACH MENTS
Tow only the attachments that are recommended by and
comply with specifications of the manufacturer of your trac-
tor. Use common sense when towing. Too heavy of a load,
while on a slope, is dangerous. Tires can lose traction with
the ground and cause you to lose control of your tractor.
SERVICE MINDER/HOUR METER
Service minder shows the total number of hours the engine
has run and indicates when the engine or mower needs
servicing. After every 50 hours of operation the oil can
icon will stay on for 2 hours or until a manual reset occurs.
To reset the display manually turn the ignition switch to
the on position, then the off position five times (1 second
on, 1 second off). To service engine and mower, see the
Maintenance section of this manual.
NOTE: Service minder runs when the ignition key is in any
position but "STOP". For accurate reading, be sure key
remains in the "STOP" position when engine is not running.
