I ran A 915 for many years for my father, very good machine if its in shape be sure to check straw walkers daily . I learned the hard way, one came loose and it broke in half. also be sure to replace or check the bearing behind the clean grain fan. This is the bearing that was the most to go out on ours. not to bad to fix in off season but a real b--th when your in a hurry. hope this helps. Also be sure the 915 is a low profile, if not walk away from it.
