TO ADJUST MOWER CUT TING HEIGHT
(See Fig. 8)
The po si tion of the at tach ment lift le ver (A) de ter mines the
cut ting height.
• Put attachment lift lever in desired cutting height slot.
The cutting height range is ap prox i mate ly 1" to 4". 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 conditions, height of
grass and types of grass being mowed.
• The average lawn should be cut to approximately
2-1/2" during the cool season and to over 3" during
hot months. For healthier and better looking lawns,
mow often and after moderate growth.
• For best cutting performance, grass over 6" in height
should be mowed twice. Make the first cut relatively
high; the second to de sired height.

TO ADJUST GAUGE WHEELS (See Fig. 9)
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:Adjust gauge wheels with tractor on a flat level
surface.

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. 10)
Only use if you are certain no children or other bystanders
will enter the mowing area.
• Move motion control lever to neutral 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.
OPERATION
• Adjust mower to desired cutting height (See “TO AD-
JUST MOWER CUT TING HEIGHT” in the Operation
sec tion of this manual).
• With mower in desired height of cut po si tion, gauge wheels
should be assembled so they are slightly off the ground.
In stall gauge wheel in appropriate hole with shoulder
bolt, washer, washer, and lock nut and tighten se cure ly.
• Repeat for opposite side installing gauge wheel in same
adjustment hole.
TO MOVE FORWARD AND BACKWARD
(See Fig. 7)
The direction and speed of movement is controlled by the
motion control lever. (J)
• Start tractor with motion control le ver in neutral position.
• Release parking brake.
• Slowly move motion control lever to desired position.
