An agricultural planter for row crops has conventional pull-type row units mounted to a frame at a relatively wide spacing for planting a crop such as corn. Push-type row units, each capable of planting two rows at a spacing which is one-third of the wide spacing are mounted to be pushed by the frame so that when both front and rear row units are used, a much narrower row spacing for beans or wheat, for example, can be achieved. The furrow openers on the push-type units are staggered fore-and-aft to avoid plugging of adjacent gauge wheels with field trash or clods of soil.

Apparatus for planting crop at a first or a second row spacing comprising: a frame; a plurality of first row units; a plurality of first mounting means for mounting said first row units to said frame at said first spacing between adjacent units, said first mounting means connecting said row units to be pulled by said frame and for permitting individual ones of said first row units to conform to ground contour independently of the other row units; a plurality of second row units; a plurality of second mounting means for mounting said second row units to said frame at a fixed lateral spacing and located between adjacent ones of said first row units laterally and spaced from said first row units in the fore-and-aft direction, said second mounting means mounting said second row units to be pushed by said frame and permitting individual ones of said second row units to conform to ground contour independently of the otehr row units, whereby when only said first row units are in use, the crop will be planted at said first row spacing, and when said first and second units are in use, the crop will be planted at said second row spacing.
