ABSTRACT:
A cultivating implement has transversely opposing sub-frames slidably mounted in the main frame of the implement to permit lateral positional adjustment of work implements carried by the sub-frames. The work implements are supported by a mounting apparatus providing a tilt adjustment, a horizontal rotational adjustment, and a transverse spacing adjustment for each respective work implement. A tilt control plate limits the transverse tilting movement of the work implement, while a rotation control plate limits the rotational movement of the work implement in a horizontal plane. A rotatable powered brush attachment can be supported on the sub-frame to provide a gentle cultivating action for the edges of plastic material covering the crop row. A pivot linkage operated through a hydraulic actuator provides simultaneous lateral movement of the opposing sub-frames to affect selective positional adjustment of the work implements. The frame is pivoted to the hitch to offset side hill operation.
