摘要：
This disclosure is directed to the field of agricultural machinery and relates to implements generally used in combination with a multi-row soil trench closing mechanism. Specifically, the disclosure relates to row treating units adapted to be attached to and following a multi-row planter and incorporating a combination of tools that includes a seed trench closing wheel assembly and a firming/packing wheel assembly. The deployment of and down force exerted by the packing wheel is independently adjustable and controlled using pneumatic air bag operators and the soil penetration of the trench closing wheels is limited.
