1. A row unit for a work vehicle, the work vehicle defining a vehicle longitudinal axis, the row unit configured to be attached to the work vehicle with a plurality of other row units for movement across a field, the row unit comprising:
a row unit frame including a closer frame, the closer frame defining a longitudinal axis and a transverse axis, the closer frame being supported for rotational movement about a substantially vertical steering axis to vary a turning angle between the longitudinal axis of the closer frame and the vehicle longitudinal axis; and
a closer implement assembly that includes a first closer implement, a second closer implement, and a walking beam construction, the first closer implement and the second closer implement attached to opposite areas of the walking beam construction, the walking beam construction rotationally attached to the closer frame to support rotation of the closer implement assembly about the transverse axis, the first closer implement configured to move ground material into a ground opening from one side as the work vehicle moves across the field, the second closer implement configured to move ground material into the ground opening from an opposite side as the work vehicle moves across the field.
