ABSTRACT OF THE DISCLOSURE Disclosed herein is a soil aerating device which is adapted for connection to a powered vehicle, which includes a first frame rotatably supporting a drum carrying a plurality of core-forming tines adapted to penetrate the ground or turf to be aerated and remove a plug of soil and/or grass as the drum is rolled over the surface of the ground or turf, and which further includes a second frame having forward and rear portions. The first frame is pivotally connected to the rear portion of the second frame for limited relative pivotal movement between the two frames and the forward portion of the second frame is pivotally connected to the vehicle for pivotal movement of the two frames relative to the vehicle between a raised position wherein the drum and tines are disengaged from the ground or turf and a lowered position wherein the drum is in engagement with the ground or turf. An actuator means, such as a double-acting, hydraulically-actuated ram, connected between the vehicle and the second frame moves the two frames between the raised and lowered positions and applies a downward force on the second frame, when the two frames are in the lowered position, to thereby transfer a portion of the weight of the vehicle to the drum through the second frame, the pivotal connection between the first and second frames, and the first frame. The pivotal connec- tion between the two frames permits the first frame and the drum to pivot relative to the second frame, thereby assuring full penetration of the tines as the drum rolls over hills and down into valleys in the ground or turf with a minimal effect on the ground-engaging traction of the vehicle wheels.
