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.

Abstract: A seend planter shoe adapted to lift displaced soil up and out of the planting furrow or furrows being formed as the shoe is drawn through agricultural soil, substantially without compressing the soil remaining in place and defining the furrow laterally, which shoe has a prow sloping upwardly and backwardly from a forward soil-penetrating point at and depending below the bottom of the shoe proper, which is substantially planar, and side walls that diverge backwardly and upwardly, from a prow piece to which they are rigidly joined, for from about one-half to about three-quarters the length of the shoe and continuing on longitudinally of the shoe substantially in parallel for the remainder of the length of the shoe. The side walls are preferably of steel plate faced outwardly over a substantial portion of their height by wear-resistant plastic plates and marginally of their bottom edges by strips of steel plate.
