A converging row unit for planting seed potatoes includes a plurality of linear arrays of seed cups, each array disposed upon a flexible endless belt and having an upwardly moveable portion and a downwardly moveable portion. The upwardly moveable portion passes through a seed pick region wherein each seed cup can draw a seed, while the downwardly moveable portion progresses to a point of discharge of the seed. The linear arrays are laterally spaced apart from each other in the upwardly moveable portion, and converge together in the downwardly moveable portion, toward to the point of discharge.

In one aspect there is provided a planting unit for singulating a plurality of seeds, said planting unit comprising a seed holder, a seed discharge, at least one drive unit and a seed singulator. The seed singulator further comprises an open top, a stepped bowl configuration having a lower inner circular wall and an upper outer circular wall, and a seed singulating ledge having a seed receiving area and a seed singulation area. The seed singulating ledge is positioned between the lower inner circular wall and an upper outer circular wall, and is driven by the drive unit to rotate relative to the upper outer circular wall along a first direction to move one or more of the plurality of seeds from the seed receiving area to the seed singulation area.
