Operating Tips
For best results, do not cut wet grass.
New grass, thick grass, or wet grass may require a narrower cut.
For a healthier lawn, never cut off more than one-third of the total length of the grass.
Your lawn should be cut in the fall as long as there is growth.
Adjust ground speed according to the condition of the lawn.
