ABSTRACT:
Disk gangs are resiliently suspended from an implement frame by retroverted flat spring members. Flat surfaces of the springs are oriented perpendicularly to the disk blade shaft to thereby permit vertical and fore-and-aft flexing of the disk gangs as obstacles are encountered and yet minimize lateral movement of the gangs to retain gang blade alignment between front and rearwardly positioned disk gangs.
