A ground-opening apparatus for an agricultural implement. The ground-opening apparatus comprises an opening disc for excavating a furrow in the ground, and a support assembly securing the opening disc to the agricultural implement. The support assembly comprises an upper bar, a lower bar, a forward bar, and a rearward bar. The upper bar and the lower bar extend generally in parallel relationship. The lower bar and the rearward bar are joined at a lower, rearward joint. A rotational axis of the opening disc extends through the lower, rearward joint of the support assembly.

A tool assembly is provided for a planter row unit and resides at the forward end of the row unit beneath the tool bar. The assembly includes a bracket assembly connected to the row unit, with a ground engaging tool removably mounted on the bracket assembly for movement between raised and lowered positions. A linear actuator controls the position of the tool. The tool may also include a depth control mechanism. Different tools can be interchanged on the bracket assembly.
