Abstract
Apparatus useful for aerating soil, especially grass or hay ground. The apparatus is intended to be towed by a farm tractor, and the apparatus includes elongated spikes on a cylindrical drum. As the apparatus is towed across a field, the spikes penetrate the soil and loosen it as well as providing openings in the soil to improve absorption of water. This reduces water run-off. The spikes are secured to bands encircling the drum, and the spacing between bands is adjustable so that the spacing between spikes can be adjusted.

Field aerator apparatus comprising:
- (a) a frame;
- (b) at least one cylindrical drum member rotatably carried by said frame for rotation about the longitudinal axis of said drum member;
- wherein said drum member has a diameter in the range of about 2 to 4 feet;
- (c) attachment means comprising a tongue member connected to said frame for connecting said apparatus to a towing vehicle;
- (d) a plurality of band members carried on the periphery of said drum;
- wherein said band members are adjustably movable axially along said drum;
- and
- (e) a plurality of elongated spike members, each having a base end and a tapered free end, wherein said base end is secured to one of said bands, and wherein said free end projects radially outward from said drum member;
- wherein a plurality of said spike members are detachably secured to each of said band members;
- and wherein said spike members have a thickness in the range of about 0.5 to 1 inch;
