The Extractor uses two hardened steel tines to dig deep into the ground and zero in on the material that needs to be removed, while leaving most of the soil in place. Available AR-400 steel, intricately serrated tines can cut roots down deep. A rounded bottom provides added strength and increased leverage. Standard shapes and sizes include a 36-in. model for tractors and skid steers and a 48-in. model for wheel loaders, with custom sizes available.
