The 24-foot STH2024 Spike Tooth Harrow cuts through clods, manure and grasses easily to help break material into finer pieces so that it can be spread evenly across the ground. It does an excellent job of smoothing garden plots, fields, arenas, and landscaping areas. Used properly, it loosens crusted soil, aerates legume crops such as alfalfa, and uncovers overwintering insects. The harrow can be used to spread manure, grass clippings, leaf litter, previous crop stubble and gravel on driveways; and can help incorporate fertilizers, herbicides, granular products, and broadcast seed into the soil.
