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 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 GAUGE WHEELS (See Fig. 9)
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 prop-
er position to help prevent scalping in most terrain conditions.
NOTE: Adjust gauge wheels with tractor on a flat level
surface.
• Adjust mower to desired cutting height (See “TO AD-
JUST MOWER CUT TING HEIGHT” in this sec tion of
manual).
• 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.
• Repeat for all, installing gauge wheel in same adjust-
ment 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 hesitat-
ing or cutting off when operating your equipment on rough,
rolling terrain or hills.
•
Select desired height of cut (see "TO ADJUST MOWER
CUTTING HEIGHT")
• Start mower blades by engaging at tach ment clutch
control.
TO ADJUST MOWER CUTTING HEIGHT
(See Fig. 8)
The position of the attachment lift lever (A) determines the
cutting height.
• Put attachment lift lever in desired cutting height slot.
• Slide pointer tab (T) to desired cutting height as a
reminder for next time you mow.
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 conditions, height of grass
and types of grass being mowed.
• The average lawn should be cut to approximately
2-1/2" during the cool season 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.
