First Claim
1. An agricultural row unit comprising:
- a towing frame for being coupled to a tractor;
an attachment frame adapted to be rigidly connected to the towing frame;
a linkage coupled to the attachment frame;
a row unit frame having a forward end coupled to the linkage to permit vertical pivoting movement of the row unit frame relative to the attachment frame; and
a closing-wheel assembly includinga support arm having a leading end coupled to the row unit frame,a hub assembly mounted at a trailing end of the support arm and having a wheel-fastening mechanism with one or more removable fasteners, anda closing wheel connected to the hub assembly with the one or more removable fasteners such that the closing wheel is interchangeable with different types of modular closing wheels.

Abstract
An agricultural row unit includes a towing frame, an attachment frame, and a linkage. A row unit frame has a forward end coupled to the linkage to permit vertical pivoting movement of the row unit frame relative to the attachment frame. A closing-wheel assembly includes a support arm having a leading end coupled to the row unit frame, and a hub assembly mounted at a trailing end of the support arm. The hub assembly has a wheel-fastening mechanism with one or more removable fasteners. The closing-wheel assembly further includes a closing wheel connected to the hub assembly with the one or more removable fasteners such that the closing wheel is interchangeable with different types of modular closing wheels.
