Intended Use
The NorTrac 3-Pt. Spike Tooth Harrow is built and designed for cutting through clods, manure, and
grasses to break up material into finer pieces so that it can be spread evenly across the ground. The
harrow does an excellent job of smoothing garden plots, fields, arenas, and landscaping areas. 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
driveways; and can incorporate into the soil fertilizers, herbicides, granular products, broadcast seed,
and overseeding. It also helps to remove gopher mounds, ant hills, ridges lifted by tillage implements,
sticks, and small limbs from grassy areas. Its 90" working width and Category I, 3-point hitch makes it
compatible with tractors up to 45 HP and is Quick Hitch adaptable. The teeth can be adjusted to 10
different angles, ranging from almost flat for providing the best flow-through of residue to straight up &
down for the most aggressive position used to fluff up the soil.
