TURF AERATING APPARATUS ABSTRACT OF THE DISCLOSURE A turf aerator includes a wheel-supported frame and drive means for propelling the frame across the ground at a predetermined rate. A pair of substantially vertical tine arms each having a plurality of downwardly directed turf coring tines attached to the lower end thereof are mounted on the frame for alternate penetrating engagement with the ground. A tine arm actuating mechanism produces an essen- tially elliptical movement of the upper end of each tine arm, the major axis of the elliptical movement being substantially vertical. A rocker mechanism indirectly connects the lower end of one tine arm with the lower end of the other tine arm such that the horizontal movement of one tine arm with respect to the frame upon engagement of that tine arm with the turf produces an equal and opposite horizontal movement of the other tine arm and vice versa. The aerator produces a sub- stantially vertical insertion and withdrawal movement of the tines and a resultant minimal disturbance of the surrounding turf area.
