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.
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.
Put attachment lift lever in desired cut-
ting 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 condi-
tions, 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
de sired height.
3. Repeat for all, installing gauge wheel
in same adjustment hole.
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 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

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.
TO STOP MOWER BLADES

CAUTION: Do not operate the mower
without either the en tire grass catcher, on
mowers so equipped, or the deflector shield
(S) in place.
NOTE: Adjust gauge wheels with tractor on
a flat level surface.

(See “TO AD JUST MOWER CUT TING

tion, gauge wheels should be assembled
