ABSTRACT:
A coulter mounting assembly includes a torsion tube that absorbs upward movement of the coulter while maintaining downward force on the coulter. The torsion tube is mounted on a support beam which depends from a farm implement. A lever arm attaches to the torsion tube and supports a strut which allows the coulter to swivel about a vertical axis. The coulter rotatably attaches to an arm which is attached to the strut.
