ABSTRACT OF THE DISCLOSURE A disc gang section comprising a plurality of rotatable disc blades which are pivotally mounted as a unit to the horizontal upper gang tube of the disc frame 80 as to travel in an arc toward the rear of the disc implement when one or more of the blades of the disc gang strikes a solid object. Ground pressure of the blades is controlled by a helical coil spring or springs located above the upper gang tube. The helical spring encircles a tension link which extends from a pivot pin which pivotally mounts the disc gang section to the upper gang tube of the disc frame. A spring abutment is rigidly mounted to the upper gang tube so as to divide the spring from the pivot pin and allow the disc gang section to pivot away from the upper gang tube upon hitting an obstruction and properly align the disc blades once the obstruction has been cleared by the blades and the spring biases the blades to the normal working position.
