A disc tillage implement has an implement frame mounted on wheels for movement along the ground. A plurality of disc assemblies is substantially equally spaced along a lateral frame member, each disc assembly comprising a pivot bracket pivotally attached to the lateral frame member about a substantially vertical bracket pivot axis, and a disc arm attached to a lower portion of the pivot bracket, with a disc rotatably attached to a bottom end of the disc arm. A control mechanism pivots the pivot brackets of each disc assembly about the corresponding bracket pivot axis of each disc assembly to a selected operating position.
