Abstract:

A potato planter (10) having a horizontally disposed auger housing (23) divided longitudinally into two halves by separator plate (37), said housing being open at the top at the forward end for receiving seed potatoes from seed hopper (11) and open at the bottom at the rearmost end for dropping seed potatoes into a planting furrow. A pair of primary single blade augers (20) disposed for axial rotation within said housing along and adjacent to each side of separator place (37). A pair of secondary filler blade augers (21), each in interfitting parallel axial relationship with a primary auger so as to interfit the filler blade of a secondary auger between the reach of the blade of each primary auger so as to form a plurality of traveling compartments between the unfilled reaches of the blade of the primary augers and the sides of the separator plate for transporting seed potatoes from the forward end of the auger housing to the rearmost opening.
