The average lawn should be cut to approximately 2-1/2
inches during the cool season and to over 3 inches
during hot months. For healthier and better looking
lawns, mow often and after moderate growth.
For best cutting performance, grass over 6 inches
in height should be mowed twice. Make the fi rst cut
relatively high; the second to desired height.
TO ADJUST GAUGE WHEELS (See Fig. 7)
Gauge wheels are properly adjusted when they are slightly
off the ground when mower is at the desired cutting height
in operating position. Gauge wheels then keep the deck
in proper position to help prevent scalping in most terrain
conditions.
NOTE: Be sure tractor is on a fl at level surface.
Lower mower and adjust mower to desired cutting
height(See "TO AD JUST MOWER CUT TING HEIGHT"
in this sec tion of manual).
Remove retainer spring and clevis pin which secure
each gauge wheel bar.
Lower gauge wheels to ground. Raise gauge wheels
slightly to align holes in bracket and gauge wheel bar
and insert clevis pin. Gauge wheels should be slightly
off the ground.
Replace retainer spring into clevis pin.
Be sure all gauge wheels are in the same setting.

rolling terrain or hills.

REVERSE OPERATION SYSTEM (ROS)
Your tractor is equipped with a Reverse Operation System
(ROS). Any attempt by the operator to travel in the reverse direc-
tion 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 -
Move motion control lever to neutral (N) position.
With engine running, turn ignition key counterclockwise
to ROS "ON" position.
Look down and behind before 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
