ABSTRACT:
A strip tillage implement includes a plurality of forward disk gang members for sizing plant residue. An upright tool support bracket extends rearwardly from the rear frame member and defines a downwardly opening accommodation space at a top portion of the bracket for a closing disk assembly rockshaft or support. The bracket includes a lower end supporting a parallel linkage that carries a clearing tool assembly in a generally constant horizontal attitude as the linkage pivots with movement of the clearing disks over obstacles. A tool support arm is pivotally connected to the bracket adjacent the parallel linkage and below the rear frame member. A closing disk arm supported from the rockshaft can be rotated to adjust down pressure or to lift the closing disk is completely out of ground contact. Closing disk spacing and disk angle are adjustable to provide the desired berm shape. Each closing disk arm is relatively long and independently supported to reduce torsional forces and improve plugging resistance of the units.
