The first combine I rode in was a MF 410IJ when I was 5 yrs. old,circa 1970. The first combine I drove was a 1975 6600 with that fabulous "twist the knob to get reverse" tranny and 15'head w_ a Hiniker floating sickle,I don't know how the beans made it over that 2" ramp!! Now,25 years later,we have a '92 9600 and '98 9610,both bought used,which my 2 boys love riding in. D.W.
