Start tractor and release parking brake.
Slowly depress forward (K) or reverse
(L) drive pedal to begin movement.
Ground speed increases the further
down the pedal is depressed.
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 condi-
tions such as trimming at slow speeds
may cause the cruise control to disen-
gage. Do not use the cruise control on
slopes, rough terrian or while trimmimg or
turning.
With forward drive pedal 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.
The average lawn should be cutto approxi-
mately 2-1/2 inches during the cool season
and to over 3 inches during hot months.
For healthier and better looking lawns,
mow often and after moderate growth.
For best cutting performance, grass
over 6 inches in height should be
mowed twice. Make the first cut rela-
tively 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 condi-
tions.
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
position, gauge wheels should be
assembled so they are slightly off the
ground. Install gauge wheel in appro-
priate hole. Tighten securely.
3. Repeat for all, installing gauge wheel
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.
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.
