Bruh, it says right in the title, it's a 4 row.

@@terrypercy he is saying that combine could handle a 6 or 8 row cornhead back in the day. I don't question the capacity of the combine but those corn heads had a hard time taking the stalks at that speed. An L Gleaner and black head would do better.

@John Sluder When I was a kid the fastest combine I saw was an N7. It was a new combine back then and it had an 12 row head. That was in the late 1970's or early 1980's when corn was considered good at 150 bu/acre in my area. Now you got to have closer to 250 or you are disappointed. That farmer along with a slug of others were out of business within a few years due to low prices. Actually the fastest I had ever seen after that were N6 combines with 6 row heads. There were a few in the area and they would just fly. One guy that was near the CaseIH dealer I worked at in the 1990's was not only fast with his N6 and 8 row head but our combine mechanic at the dealership walked out in the field to see how much corn was left on the ground and he said there was nothing. One of our salesmen said he'd never seen a combine move like that. That was when the 2188 was the big CaseIH machine. Today N6 and N7 combines are pretty much all gone from our area. Not many gleaners at all but drive 50 or 60 miles south and they pop up all over.

Most of todays yields are not any better than I was getting back in the early seventies when this machine was in planning stages and the 105 was king. Now, Just like then the biggest yields are in the coffee shop
