Abstract
A stationary, formed metal cap covers the bearing assembly of the rotatable firming wheel to protect the bearings against the ingress of mud, residue and moisture. A smooth, convex, exposed outer surface on the cap discourages the accumulation of residue and mud between the rotating wheel and its stationary support arm so as to keep the wheel freely rotating during its rolling movement in the seed trench. A flat, band-like, circular edge around the periphery of the convex surface is received within a circular groove on the face of the wheel to obstruct the ingress of moisture and materials at that location and disposes the marginal periphery of the convex surface in a substantially flush condition with the surface of the wheel to prevent wrapping and accumulation of trash.
