• Put attachment lift lever in desired cutting height slot.
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.
TO ADJUST GAUGE WHEELS (See Fig. 9)
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.
