• Put attachment lift lever in desired cutting
height slot.
The cutting height range is ap prox i mate ly 1
to 4" (25,4 to 101,6 mm). 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 approxi-
mately 2-1/2" (63,5 mm) during the cool
season and to over 3" (76,2 mm) during
hot months. For healthier and better look-
ing lawns, mow often and after moderate
growth.
• For best cutting performance, grass over
6" (152,4 mm) in height should be mowed
twice. Make the first cut relatively high; the
second to de sired height.
TO ADJUST GAUGE WHEELS
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 proper position to help prevent scalping
in most terrain conditions.
NOTE: Adjust gauge wheels with tractor on
a flat level surface.

(See "TO AD JUST MOWER CUT TING
HEIGHT" in this sec tion of manual).
9/16"
