Abstract:
1. A soil aeration apparatus, comprising: a tine holder member; a gear system that imparts compound motions to the tine holder member; at least one curved tine mounted to the tine holder member, the curved tine having a concave edge, an oppositely disposed convex edge, generally flat lateral side faces opposing one another, and a tip portion, wherein the compound motions are imparted to the tine holder member while the curved tine is in the ground surface to form an aeration pocket, wherein the convex edge cuts through the soil while the curved tine is in a ground surface; and a timing member coupled to the gear system, the timing member being adjustable between a first position to a second position, wherein when the timing member is in the first position, the tine penetrates a ground surface in a first penetration orientation, and wherein when the timing member is in the second position, the tine penetrates the ground surface in a second penetration orientation.
