Claim:
1. A row unit for an agricultural implement comprising: at least one closing disc configured to move soil into a trench; a coupling configured to support the at least one closing disc; a first arm having a first end coupled to a center portion of the coupling and a second end configured to rotatably couple to a support structure of the row unit; and a second arm having a first end rotatably coupled to an outer portion of the coupling and a second end configured to rotatably couple to the support structure of the row unit, wherein the outer portion of the coupling includes a bracket having a plurality of openings, and each opening of the plurality of openings is configured to receive an attachment element to rotatably couple the first end of the second arm to the bracket, wherein the outer portion of the coupling is rotatable relative to the center portion of the coupling, and rotation of the outer portion relative to the center portion drives a rotational axis of the at least one closing disc to revolve about a longitudinal axis of the center portion to enable the at least one closing disc to maintain a desired toe angle relative to a direction of travel or a desired camber angle relative to a surface of the soil as the row unit travels across a field.
