Seeding row unit having a primary actuator to adjust depth and to raise and lower the seeding row unit

Abstract

A row crop planter including a frame, a seed bin supported by the frame and configured to hold seeds, and a plurality of agricultural row units coupled to one or more seed bins. Each of the row units includes a seed deposit assembly, including a disk to cut a furrow in the soil, gage wheel, and a seed deposit chute to direct seeds into the furrow. A bar linkage is operatively connected to the seed deposit assembly. A downforce actuator is operatively connected to the bar linkage and applies a force to the disk and to the gage wheel, to cut the furrow in the soil. A primary actuator is operatively connected to the bar linkage, wherein the primary actuator raises and lowers the seed deposit assemblies, and moves the disk into the soil to cut the furrow at a depth determined by the primary actuator and the gage wheel.
