Abstract: An angle adjustable coulter wheel assembly includes a rotatable shank having a longitudinal axis defined by an upper portion of the shank. The longitudinal axis is oriented neither vertically or horizontally with respect to the ground when the assembly is mounted on a tillage apparatus. A coulter wheel rotatably mounted on the shank proximate a lower portion of the shank. An actuator rotates the upper portion of the shank about the longitudinal axis to cause the face of the coulter wheel to rotate about three orthogonal axes thereby changing orientation of the face of the coulter wheel with respect to the ground when the assembly is on the tillage apparatus. The coulter wheel assembly permits adjusting the angle of the coulter wheel in at least two planes permitting greater control over how much soil the coulter wheel disturbs during tilling.

Abstract: A tillage apparatus having a rotary harrow mounted thereon with mounting elements utilizes a cooperative combination of: a compressible material at the mounting element to permit relative motion between the harrow and the mounting element in response to a motion of the harrow; and, a hydraulic actuator operated under a first pressure to lower the rotary harrow and maintain engagement of the rotary harrow with the ground. A pressure relief element is utilized to reduce back pressure in response to the harrow striking a hard impediment on the ground during operation of the tillage apparatus in a field. The combination cooperates to reduce damage to the harrow and/or other parts of the tillage apparatus when the harrow strikes a hard impediment such as a rock.
