Backers 2-fraction star screens deliver exceptional performance on a variety of materials. Engineered to work during the rainy season, Backers let you screen when you need to regardless of the weather or source material condition. Break up clays, separate wet topsoil, compost, screened mulch, and aggregate. Specifically designed for rough terrain, the tracked undercarriage models bring an additional level of value and mobility. Add an optional grizzly to scalp off extra-large coarse material before it enters the screen.
