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. It also helps to remove gopher mounds, ant hills, ridges left by tillage implements, sticks, and small limbs from grassy areas. The teeth can be set at two angle – 40 degrees off vertical for the best flow-through of residue and 22 degrees off vertical for aggressive "fluffing" of the soil.
