WSM hogging and screening machinery is ideal for converting green yard waste materials into recyclable wood fiber and compost products. WSM's Horizontal Hog features an aggressive power feed mechanism that provides extremely effective processing of brushy green waste material by gripping and compressing the material as it feeds into the hog. WSM screening machinery (Disc Screens, Trommel Screens, Oscillating Screens) are effective at producing sized fractions for use as compost, boiler fuel, and landscape mulch products.
