摘要：
A row unit for a work vehicle includes a row unit frame with a closer frame. The closer frame defines a longitudinal axis and a transverse axis. The closer frame is supported for rotational movement about a substantially vertical steering axis to vary a turning angle between the longitudinal axis the vehicle longitudinal axis. The row unit includes a closer implement assembly with first and second closer implements and a walking beam construction. The first and second closer implements are attached to opposite areas of the walking beam construction. The walking beam construction is rotationally attached to the closer frame to support rotation of the closer implement assembly about the transverse axis. The first and second closer implements are configured to move ground material into a ground opening from opposites sides as the work vehicle moves across the field.
