Mulching Tips

Mower is designed to re-cut grass clippings into short lengths.
Set mower at highest cutting height when mowing in rough ground or in tall weeds.
Do not cut the lawn when it is wet.
For best results, adjust the mower cutting height so that the mower cuts off only the top third of the grass blades.
Change your cutting pattern from week to week.
