Very good display, we have a 1929 Sunshine Waterloo (self propel) and a Allis Chalmers All Crop (self propel). Both attracted interest in our local threshing demonstrations.
Most dont know it.....but the all crop 66 was meant to go the wrong way around the field ,cut / harvest only the heads . After finishing.....go the opposite way around the fields and under cut the stubble with a sickle mower or hay bine and bale it for straw. They were designed for this !
