Abstract:
1. A soil aerator, comprising: a frame connectable to a tow vehicle which transmits a pulling force from the vehicle to the frame via a one-point hitch member; an aeration apparatus coupled to the frame such that the frame transports the aeration apparatus over a ground surface when the frame is connected to the tow vehicle, the aeration apparatus having a set of aeration tines to form to aeration pockets; a user-controlled lift device that raises the aeration apparatus away from the ground surface while the frame is connected to the tow vehicle via the one-point hitch member, the lift device being coupled to the frame so as to temporarily lift the aeration apparatus away from the ground surface to prevent damage to the aeration tines, wherein the lift device raises the aeration apparatus away from the ground surface while being towed without requiring a three-point hitch system on the tow vehicle; and one or more rear wheels coupled to the frame and fully rotatable about a rear wheel axis, wherein the rear wheel axis remains a generally fixed distance from a rotational axis of the aeration apparatus while the aeration apparatus is being raised away from the ground surface.
