I don't know about a 470 but our 465 can shell 2500 to 3000 bushels an hour in 150 bu_acre corn, a 12 row 30" head, unload on the go, and three semi's. Our problem is keeping up with the trucks. Also the 465 will run out of horsepower when unloading on the go in hills at 5 mph. This is not realy a complaint as we rarely have any need to run that fast.
