The method for planting potatoes at high speed includes the steps of providing a press wheel behind the seed release mechanism opening a furrow in a soil dropping potato seed pieces at spaced intervals in the furrow such that each seed piece or a portion thereof intersects a forward shadow of the press wheel, and catching and decelerating each seed piece against the soil in the furrow thereby reducing set roll in each seed piece. In an alternate embodiment a pair of spaced-apart press wheels are used. These alternate press wheels are mounted astride the furrow in a positive-camber alignment for moving the soil of the furrow against the seed piece.
