Abstract:
1. A twin row seed planter comprising: a pair of planting units operable to seed a pair of closely-spaced adjacent furrows forming a single harvesting row, with a first one of the planting units corresponding with a first one of the furrows and a second one of the planting units corresponding with a second one of the furrows, said first planting unit including a first rotatable metering wheel having a plurality of circumferentially spaced seed-receiving first cells, said second planting unit including a second rotatable metering wheel having a plurality of circumferentially spaced seed-receiving second cells, with the second metering wheel being positioned relative to the first metering wheel to present an angular relationship between the first and second cells; and a drive mechanism operable to supply power to the planting units so as to cause rotation of the wheels, said second metering wheel being drivingly disconnectable from the drive mechanism and repositionable relative to the first metering wheel to adjust the angular relationship between the first and second cells so as to vary spacing of the seed in the second furrow relative to seed in the first furrow.
