To Use Cruise Control; System Characteristics - Craftsman 917.28890 Operator's Manual

TO USE CRUISE CONTROL
The cruise control feature can be usedfor
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
causethe 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 releasethe lever.

TO ADJUST MOWER CUFFING HEIGHT
The position of the attachment lift lever (A)
determines the cutting height.
• Put attachment lift lever in desired cut-
ting height slot.
• Slide pointer tab (T) to desired cutting
height as a reminder for next time you
mow.
The cutting height range is approxi-
mately 1" to 4". The heights are mea-
sured 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 ap-
proximately 2-1/2 inches during the cool
season and to over 3 inches during hot
months. For healthier and better look-
ing 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 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
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 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 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.
TO STOP MOWER BLADES -
disengage attachment clutch control.
_IbCAUTION: Do not operate the mower
without either the entire grass catcher,
on mowers so equipped, or the deflector
shield (S) in place.
