摘要：
A row unit for an agricultural implement includes a closing disc configured to move soil into a trench. The closing disc is rotatably coupled to a first portion of a support structure via a first arm to facilitate vertical movement of the closing disc relative to the support structure. The row unit also includes a packer wheel positioned aft of the closing disc and configured to pack soil over the trench. The packer wheel is rotatably coupled to a second portion of the support structure via a second arm. The closing disc and the packer wheel are independently movable relative to one another.
