  • Spikes for field aerator
    Patent number: 5586603
    Abstract: Spikes are described for use in apparatus useful for aerating soil, especially grass or hay ground. The elongated spikes are secured to 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. The spikes are preferably 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
    Patent number: 5460229
    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.
