TO USE CRUISE CONTROL
The cruise control feature can be used for
forward travel only.
SYSTEM CHARACTERISTICS
The cruise control should only be used
while mowing or transporting on relatively
smooth, straight surfaces. Other con di tions
such as trimming at slow speeds may cause
the cruise control to dis en gage. Do not use
the cruise control on slopes, rough terrian
or while trimmimg or turning.
• With forward drive pedal (K) depressed to
desired speed, pull cruise control lever (J)
up and hold while lifting your foot off the
pedal, then release the lever.
To disengage the cruise control, depress the
brake pedal or tap on forward drive pedal.
TO ADJUST MOWER CUT TING HEIGHT
The po si tion of the at tach ment lift le ver (A)
de ter mines the cut ting height.
A
• 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).
2. 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 ap pro pri ate hole. Tighten
se cure ly.
3. Repeat for all, installing gauge wheel in
same adjustment hole.

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 equipment
on rough, rolling terrain or hills.
1. Select desired height of cut with attach-
ment lift lever.
2. Start mower blades by engaging at tach-
ment clutch control.
