摘要：
An apparatus and system for adjustably controlling the position and depth of row closer wheels in no-till planting applications, the apparatus comprising a frame, a piston movably secured at the top to the frame, upper and lower parallel arms disposed about the piston and movably secured at one end to the frame and at the other end to a hub stem, and a set of piston arms each movably secured at the top to one of the upper or lower parallel arms and at the other end to the bottom of the piston. A closing wheel assembly having a closing wheel frame and a set of closing wheels pivotally mounted to a lever on a single axle assembly allows the operator to change the angle at which the closing wheels intersect the ground surface during use. Accordingly, as the angle of the lever is manipulated, the angle of the closing wheel pivotally mounted to that lever changes in the vertical and/or horizontal dimensions.
