TO ADJUST MOWER CUTTING HEIGHT
The position of the attachment lift lever (A)
determines the cutting height.
• Put attachment lift lever in desired cut-
ting height slot.
The cutting height range is approximate-
ly 1" to 4". The heights are measured
from the ground to the blade tip with the
engine not running. These heights are ap-
proximate and may vary depending upon
soil conditions, height of grass and types
of grass being mowed.
• The average lawn should be cut to ap-
proximately 2-1/2" during the cool sea-
son 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 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: Adjust gauge wheels with tractor on
a flat level surface.
1. Adjust mower to desired cutting height
(See "TO ADJUST MOWER CUTTING
HEIGHT" in this section of manual).
2. With mower in desired height of cut posi-
tion, gauge wheels should be assembled
so they are slightly offthe ground. Install
gauge wheel in appropriate hole. Tighten
securely.

TO OPERATE MOWER
Your tractor is equipped with an operator
presence sensing 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 equip-
ment on rough, rolling terrain or hills.
1. Select desired height of cut with at-
tachment lift lever.
2. Start mower blades by engaging at-
tachment clutch control.
TO STOP MOWER BLADES
Disengage attachment clutch control.
_CAUTION: Do not operate the mower
without either the entire grass catcher,
on mowers so equipped, or the deflector
shield (S)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 direc-
tion with the attachment clutch engaged
will shut off the engine unless ignition key
is placed in the ROS "ON" position.
A_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.

Repeat for all, installing gauge wheel
in same adjustment hole.
