like the previous posters said a six row head is way too much for a 4400. I have a 4400, and I run a five row narrow head that I built several years ago. It does pretty good in 100 to 120 bu corn. (average around here) This year it rained all summer, and when I was picking my 190 bu corn, it was all she wanted. Threshing capacity was not a problem, the main problem was that I was overloading the clean grain elevator on the combine. I have also had this happen in high yeilding wheat and soybeans on this combine. I think the biggest problem is that the 4400 was designed back in the late 60s when 100 bu corn, 50 bu wheat, and 35 bu beans considered a bumper crop in most parts of the country. Now with new varieties and better management we are making nearly twice those yeilds, and the old machine was just not designed to handle that muuch crop. The head that I built was made from taking my 444 cornhead apart and adding a picker unit from a 2 row head off a junked 3300 that a neighbor had put in the woods. I then got new polytin for for the entire head. My only cost was for the polytin, because my neighbor gave me the picker unit which was in very good shape. Deere actually made some five row heads back in the late 70s and early 80s, but they were not very popular. I have only seen one of them that a guy across the county runs on a 79 4400. His was where I got the idea from. This winter my shop project is a 5 shank ripper with a gang of rolling baskets behind it. I hope 125 horses will pull it, if not, I guess I will have to hit the auctions and find a bigger tractor, or drop a shank and pull four.
