ABSTRACT:
A potato seed planter in which seeds are loaded into cups on an endless conveyor from a hopper of a seed receptacle. The conveyor is driven on upper and lower sprockets and arranged on the receptacle with the cups in two parallel rows in staggered constant relationship and moving upwardly through the hopper for seed loading. The cups pass around the upper sprocket, invert and enter a contoured tube thereat and descend in an attached discharge tube to a furrow. The cup bottoms are inclined transversely and support the seeds in their descent against the wall of the discharge tube. At the bottom the seeds are discharged from the planter and guided by the transversely inclined cup bottoms are deposited one by one alternately from one row and then the other in the furrow with precision heretofore unachieved. The planter further comprises a wheeled frame and one or more, attached, laterally extending, flexible frames upon which the receptacle is supported. The receptacle is size adjustable and the planter is adaptable to plant in several rows simultaneously.
