Now you can mow right over rocks, stumps, stones & 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 & Brush mower. It takes just a few minutes to install & is the perfect solution for mowing overgrown pastures, roadside ditches, & river banks--places where vegetation grows & where rocks & stumps might be hidden from view. Not intended for brush.
