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.
• The average lawn should be cuttoapproxi-
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

Adjust mower to desired cutting height
(See “TO ADJUST MOWER CUTTING

position, gauge wheels should be
assembled so they are slightly off the
ground. Install gauge wheel in appro
priate hole. Tighten securely.

or cutting off when operating your equip
ment on rough, rolling terrain or hills.

tachment lift lever.
