An apparatus (23, 123) includes a hinge mount top plate (22, 122), a hinge mount bottom plate (26, 126), and a pin (28) connecting the top plate (22, 122) and bottom plate (26, 126). A cam adjuster element (34, 134) includes a top aperture (46, 146), a middle aperture (47, 147), and a bottom aperture (36, 136). A first fastener (42) passes through the top aperture(46, 146) to connect the cam adjuster element (34, 134) to the hinge mount top plate(22, 122). The first fastener (42) may be disposed in different positions in the top aperture (46, 146). A second fastener (42) passes through the middle aperture (47, 147) to connect the cam adjuster element (34, 134) to the hinge mount top plate (22, 122). The cam adjuster element (34, 134) may pivot about a longitudinal axis (37) of the second fastener (42). The pin (28) is retained in the bottom aperture (36, 136). An assembly includes a disc (10), a seed boot (12, 112), and a mounting mechanism (23, 123) that allows for movement between the seed boot (12, 112) and the disc (10) about first pivot axis (29) and second pivot axis (37). |
