Abstract: A towable rear tool attachment for a towable tillage tool is configured for soil clod sizing and firming. The rear tool includes a rolling cage that rotates when being towed and is in contact with a soil surface. The rolling cage includes a pair of circular-shaped end plates located at each end of the rolling cage, a ring-shaped support plate, in parallel with and between the end plates, structural members arranged equally spaced apart around a circumference of the end plates and the support plate, forming a cage-like structure. At least one of the structural members having a removable section between one end plate and the support plate configured for easy removal of rocks and other objects that can be picked and trapped inside of the rolling cage.

Abstract: A tillage tool achieves stability at higher speed ranges by providing stabilization with additional damping through damping elements on the front support wheels and on the constant level linkage and on the rear tool. The tillage tool maintains maximally one longitudinally positioned unsuspended load path to the ground provided by unsuspended depth gauging wheels longitudinally positioned parallel to a front to rear rocking axis to allow for constant settings throughout the depth, speed, and field condition ranges.
