• 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 first cut relatively high;
the second to desired height.
TO ADJUST GAUGE WHEELS
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 flat level
surface.
1. Lower mower and adjust mower to de
sired cutting height(See “TO ADJUST
MOWER CUTTING HEIGHT” in this
section 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.
IMPORTANT:
Be sure to readjust gauge
wheels if you change the cutting height
of the mower deck.

engine running and the attachment clutch
engaged will shut off the engine. You must
remain fully and centrally positioned in the

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 at
tachment clutch engaged 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.
