A seed planting assembly is provided having a plurality of planting units supported by a tool bar, each of which being operable to form a seed trench in soil, plant seeds in the seed trench, and close the seed trench. Each planting assembly is supported by the tool bar via a mounting assembly that can be actuated by a vertical positioner to raise and lower individual planting units.

A pivot pin assembly is provided including a rotatable member having a hole therethrough with tapered ends, a pivot pin including a cylindrical portion and a conical portion engagable with a corresponding end of the tapered ends of the rotatable member, a pivot bearing engagable with the pivot pin to aid in rotation of said pivot pin; and a nut and bolt to lock said pivot pin to said rotatable member. The pivot pin is typically a conventional bearing having an inner race, an outer race, and bearings located between the inner and outer race. Optionally a washer is utilized to hold the bearings in place. In a preferred embodiment, the angle of the tapered end and the angle of the conical portion of the pivot pin are equal to each other and the angle is 20 degrees.

A seed flap for a disc opener associates with an air seeder operable to place seed and fertilizer into a furrow formed in the ground by the disc opener. The seed flap is formed from a non-flexible material, such as an abrasion resistant steel, and pivotally mounted to the seed tube to permit the seed flap to trail behind the seed tube and control the placement of seeds and/or fertilizer discharged from the seed tube. The pivotal mounting of the seed flap will provide movement of the seed flap relative to the seed tube to permit the seed flap to more consistently align with the bottom of the furrow and better follow the furrow bottom created by the disc opener while the disc opener is moving through a turn. A spring mechanism operably coupled to the seed flap will provide a positive force for firming the placement of the seed into the soil. A retention device, such as a clip, will be operable to hold the seed flap in an elevated, inoperable position as desired by the operator.
