This video shows some hay (alfalfa) being hauled with a 1950 John Deere Model G. The model G was the largest row-crop John Deere at the time, with more CI displacement than even the 4020 at 412 (vs 404, but not near the horse power). The G was replaced by the 70, which was replaced by the popular 720 and 730 series of John Deere two-cylinder tractors. The other tractor in the video is a John Deere 4020, which loaded the bales.
