I have a few here on our dairy farm... milk 350 cows. They run augers, move wagons at harvest time, pull my corn planter starter wagon, etc. Currently use an A, G, 70. Friday the 70 got used to unload forage boxes at the bagger. Yes, 8235R on chopper, 2 4020s and a 4320 hauling, 70 unloading! Put in about 55 loads in 8 hours.
The 70 usually only gets used when hauling longer distances and we need plenty of tractors to keep up. But it is a favorite to unload with- easy on and off, simple controls, hand clutch to ease ahead with the bagger.
