Abstract: A planting apparatus is shown having a drive wheel for turning a drive belt connected to an axis extending through a hopper. Inside the hopper, a pickup wheel having individual spokes extending radially outward is rotated by the axis. Each spoke there has an indentation just large enough to receive a seed therein upon rotation through to the bottom of the hopper having seed therein. Upon further rotation, the seed is carried by the spoke to the top of the hopper before being dropped into a funnel shaped flue. A spring loaded tapping mechanism strikes the spokes to insure that the seeds will drop from the spokes into the flue. The individual spokes may be removed for varying the space therebetween, or replaced by other spokes having different sized holes therein for the planting of different sized seeds. The seeds drop through the flue and are delivered to a furrow made by a planting foot and covered by a planter wheel.
