The cutting height range is approximately 1-1/2" to 4-1/2",
The heights are measured from the ground to tile 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 cutt=t.J.g.approximately 2-1/2
inches during the cool_d'_ 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
relatively high; the second to desired height.
