G I don't know, but it had the best hydro of any combine in it's class when it was made. I cleared a whole 8 lane intersection out with one back in '78, at the Dairy Queen in Paris, Tn. That 6 row corn head plowed all the way thru traffic, peeling everything from Peterbuilts to Datsuns, only tore up the snouts, and ripped the seat (spastic colon that day) Only problem I had was trying to find the clutch pedal on that baby, hydro's ain't got one.
