ABSTRACT:
A soil aerating device consisting of a spindle inclined from vertical but power driven to rotate about a vertical axis, and an arm rotatably mounted at its midpoint on the spindle, having a downwardly projecting tubular tine mounted at each end thereof, and being disposed just above ground level, the gyrating movement of the spindle as it rotates about a vertical axis imparting to the arm a movement having a vertical rocking component in a plane longitudinal thereto, so that said tines are alternately inserted into and withdrawn from the ground to form holes therein, and an axial rocking component around the axis of the arm, so that the arm is caused to "walk" rotatively around the vertical axis of rotation.
