ABSTRACT:
A rotary soil conditioner in the form of a cylinder fitted with pointed projecting curved tines. The tines each project to a distance from the cylinder surface that is approximately one-half the cylinder radius and are each curved in the direction of rotation of the cylinder with a radius of curvature of one-third the cylinder diameter, and with the center of the arc of each tine being on the surface of the cylinder. Each tine is preferably formed with an oval cross-section that narrows from the tine root to the tine tip, with the long axis of the oval cross-section oriented in the direction of rotation of the cylinder.
