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.

Abstract: A frame for a tillage implement includes a pair of opposing frame sections pivotally connected to a central kingpost for a folding movement between a transversely extending working position and a longitudinally extending transport position. The frame sections have mounted thereto a number of tool sub-frames carrying ground engaging working tools. The tool sub-frames are pivotally movable relative to a rockshaft carried by the frame sections so as to be rotatable between a lowered operative position and a generally vertical raised non-working position. Depth control for the ground engaging tools is accomplished through the rotation of the rockshaft about its pivot lug. The frame sections are connected at the inner end to the kingpost so that the main frame members abut when placed in the working position. Each frame member is supported by a pair of wheel assemblies at the inner and distal ends respectively.

Abstract: An improved suspension for a coulter wheel assembly of the type primarily intended for attachment to a tractor wherein the improved suspension is characterized by its construction including a plurality of pivotal support bars interconnecting a set of double disc openers with following press wheels is disclosed. The improved suspension includes a unique back angle pivot attachment of the coulter wheel assemblies to one of the pivoting support arms so that the coulter wheels and press wheels accurately track the direction of travel of a tractor, even when the direction of travel changes rapidly and frequently. A material may be deposited in the furrow created by the double disc openers attached to the improved suspension of this invention, and the depth of the furrow cut by the double disc opener may be adjusted.

Abstract: A device to provide for easy handling of dual tandem discs and similar farm implements. The device is a framework foldable on a hinge line and having wheels for transportation. The hinge line is longitudinal and provides that when collapsed, the two tandem discs are carried in line with a minimal width and when open allows the discs to be pulled in a side by side conformation to cover two parallel paths.
