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 conditions
such as trimming at slow speeds may cause
the cruise control to disengage. 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.
Todisengagethe cruise control, depress the
brake pedal or tap on forward drive pedal.
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 approximately
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
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.
3, Repeat for all, installinggauge 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 attach-
ment clutch control.
TO STOP MOWER BLADES
Disengage attachment clutch control.
_JLCAUTION:
Do not operate the mower
without either the entire grass catcher, on
mowers so equipped, or the deflector shield
(S) in place.
