Do I need a special mower?
You can Grasscycle with any mower (push, electric, gas or mulching). The mower collection bag should be removed to allow clippings to drop on the lawn. However, if your mower does not have a safety flap covering the opening where the bag fits into the chute, it is important that you purchase a retrofit kit from your hardware store. If you use a landscape service, ask them to leave the clippings on your lawn.
Will Grasscycling cause thatch and make my lawn look bad?
Grasscycling does not cause thatch buildup. Research has shown that shallow grass roots caused by overwatering and overfertilization are the primary cause of thatch build up, not grass clippings. The short clippings from regular mowing will decompose quickly and will not cover the grass surface or cause thatch.
