• Put attachment lift lever in desired cutting
height slot.
The cutting height range is ap prox i mate ly 1
to 4" (25,4 to 101,6 mm). 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 approxi-
mately 2-1/2" (63,5 mm) during the cool
season and to over 3" (76,2 mm) during
hot months. For healthier and better look-
ing lawns, mow often and after moderate
growth.
• For best cutting performance, grass over
6" (152,4 mm) in height should be mowed
twice. Make the first cut relatively high; the
second to de sired height.
TO ADJUST GAUGE WHEELS
Gauge wheels are prop er ly ad just ed when
they are slight ly 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 AD JUST MOWER CUT TING
HEIGHT" in this sec tion of manual).

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

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 equipment
on rough, rolling terrain or hills.
1. Select desired height of cut with attach-

TO STOP MOWER BLADES
Disengage at tach ment clutch con trol.
CAUTION: Do not operate the mower
without either the en tire grass catcher, on
mowers so equipped, or the deflector shield

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:
tachment clutch engaged while mowing is
strongly discouraged. Turning the ROS "ON",
to allow reverse operation with the attach-
ment 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
9/16"
