ABSTRACT:
A coulter chisel tillage tool includes a mounting apparatus for attaching a disc gang to a rockshaft. A bracket extends radially from the rockshaft and is connected to one end of a spring having its other end positioned in a retainer cup. The retainer cup is attached to one end of a rod which extends longitudinally through the spring and through an aperture formed in the mounting bracket with the other end of the rod rotatably attached to a bracket assembly. The bracket assembly includes a pair of bearing caps which rotatably engage the rockshaft and are positioned between a pair of plates which are maintained together by bolts. One of the bolts also extends through a yoke of a disc gang for rotatably mounting the disc gang for rotation about a generally vertical axis. The spring and bracket assembly permits the disc gang to rotate about the rockshaft when an obstacle is struck during normal operation.
