Abstract:
A turf aerator comprising:(a) at least a first roller having an axis of rotation, having an annular surface displaced radially away from the axis of rotation, and having a first lateral end; (b) at least a first tubular tine having inner and outer ends, and having soil input and output ports; and, (c) attaching means adapted for interconnecting the at least first tubular tine and the at least first roller, the attaching means positioning the at least first tubular tine at the first lateral end of the at least first roller, the attaching means further positioning the at least first tubular tine so that its inner and outer ends are radially displaced from the at least first roller's axis of rotation, the radial displacements of said ends being respectively less than and greater than that of the annular surface, the at least first roller having a second lateral end, and further comprising at least a second tubular tine having inner and outer ends, and having soil input and output ports; the attaching means being further adapted for interconnecting the at least second tubular tine and the at least first roller, the attaching means further positioning the at least second tubular tine at the second lateral end of the at least first roller, the attaching means further positioning the at least second tubular tine so that its inner and outer ends are radially displaced from the at least first roller's axis of rotation, the radially displacements of said ends being respectively less than and greater than that of the annular surface, the outer ends of the at least first and second tubular tines being annularly beveled, each of the at least first and second tubular tines having a side wall, the soil output port of each such tine extending through its side wall, and further comprising at least a third, a fourth, a fifth, and a sixth tubular line, each such tine having inner and outer ends, and having soil input and output ports; the attaching means being further adapted for interconnecting the at least third, fourth, fifth, and sixth tubular tines, and the at least first roller, the attaching means further respectively positioning the at least third and fifth and the at least fourth and sixth tubular tines at the first and second lateral ends of the at least first roller, the attaching means further positioning the at least third, fourth, fifth, and sixth tubular tines so that their inner and outer ends are radially displaced from the at least first roller's axis of rotation, the radially displacements of said ends being respectively less than and greater than that of the annular surface; the attaching means further respectively positioning the at least first, third, and fifth, and the at least second, fourth, and sixth tubular tines in first and second radial arrays; the first and second lateral ends of the at least first roller comprising end walls, the attaching means comprising a plurality of tine receiving channels within said walls, each tine receiving channel having a floor, the attaching means further positioning the at least first, second, third, fourth, fifth, and sixth tubular tines nestingly within said channels.
