Abstract
A seed planting apparatus includes a toolbar mounted on a tractor for traversing the ground in a direction perpendicular to the longitudinal axis of the toolbar. A plurality of seeding units are spaced laterally across the toolbar for ground penetration and planting of seeds. A ground engaging wheel is provided and a linkage connects the wheel to the toolbar for up and down movement relative to the ground. An actuator interconnects the toolbar to at least one of the linkage and wheel for selectively elevating the wheel. A bulk seed hopper is supported adjacent the wheel and a control system determines a parameter associated with the toolbar and raises and lowers the wheel to transfer weight from the bulk feed hopper to and from the toolbar.
