I am not a Gleaner expert, but we did buy an N7 2 years ago. We like it. We have not modified it yet, that is our winter project. Right now, 10 acres per hour in 50 bushel wheat is the best it will do. Although my brother the operator will never be accused of running any piece of machinery too hard. Our research befor buying included talking with John Keller. He was very helpful. He suggested the N7 over the N6 because he said the N7 had one of the best engines Allis ever made, taken from a crawler or something. The early Ns had some problems. There were some 104 upgrades. The Series 3 (end of '82 and starting '83) had most of the bugs worked out. Just shop around. For about the same price range we found combines that were patched together and seting out in the weather to the one we bought that was shedded and taken care of. Hope my little bit of experiance helps. Greg
