The “D” series flail mulchers are super heavy duty mowers designed for large areas, with heavy vegetation and/or brush. Areas like roadsides, orchards, fields, woods, roads and trails. Perfect for clearing and maintaining the more rugged landscape areas that include heavy grasses, debris, sticks, vines, branches and other wooded materials. The Farmer-Helper “D” series flail mulchers are designed for dual duty. Be it cutting the field or clearing the brambles this mulcher flail can handle the task. With a standard flail mower the material you are cutting may not be retained under the deck before it is expelled down on the ground. If you are dealing with brush and brances sometimes the material comes out from under the deck before it is fully mulched. With the “D’s” brush rakes you can keep the material in the mulching chamber longer.
