Now you can mow right over rocks, stumps, stones and into "unknown" areas without worry!The Bladeless Mowing Attachment uses extra heavy-duty 170 mil nylon cutting cords that replace the steel blade on the DR Field and Brush mower. It takes just a few minutes to install and is the perfect solution for mowing overgrown pastures, roadside ditches, and river banks--places where vegetation grows and where rocks and stumps might be hidden from view.Not intended for brush.
