= Turn knob counterclockwise (_) to lower cutting
height.
The cutting height range is approximately 1-1/4" to 4-1/4"
The heights are measured from the ground to the blade tip
with the engine not running. These heights are approxi-
mate 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
inches during the cool season and to over 3 inches
during hot months. For healthier and better looking
lawns, mew often and after moderate growth.
° For best cutting performance, grass over 6 inches in
height should be mowed twice_ Make the first cut
relatively high; the second to desired height,
