Abstract:
1. An aerator comprising: an aeration subassembly movably coupled to a frame, the aeration subassembly having a set of aeration tines mounted to a tine rack, the aeration tines being movable in a compound rotational and revolving motion relative to a ground surface to form aeration pockets in the ground surface; and an adjustment member coupled to the aeration subassembly, the adjustment member being operable to shift between a first operative position and a second operative position, wherein, when the adjustment member is shifted to the first operative position, the aeration tines are operable to contact the ground surface when the tine rack is proximal to the ground surface, and wherein, when the adjustment member is shifted to the second operative position, the aeration tines are operable to avoid contact with the ground surface without lifting the aeration subassembly away from the ground surface.
