Patent ID: 7743841

Claim:
A method of aerating a soil surface, comprising: urging a plurality of aeration tines in a compound motion including a rotational motion about a first axis and an revolving motion about a second axis, each aeration tine including: a proximal portion that is substantially longitudinally straight and comprises an adapter to secure the tine to a tine holder member, and a curved blade portion extending distally from the proximal portion and including a concave blade edge at least partially defined by a first pair of transverse surfaces and an oppositely disposed convex blade edge at least partially defined by a second pair of transverse surfaces, the concave blade edge and the convex blade edge extending generally longitudinally toward a distal tip portion; penetrating a soil surface with the plurality of aeration tines to form aeration pockets in the soil surface, the curved blade portion of each aeration tine fracturing soil as it is urged in the compound motion.
