Well Tom, the 2 area dealers that I have done business with since 1975 had nothing but trouble with the Deutz Gleaners they sold, not oil leaks, the fins would fill with, mainly soybean fuzz and corn chaff and would either burn up the back two cylinders or in a couple cases caused the engine compartment to burn. And for some reason the cooling fans would go bad about every two seasons. They lost more customers over the Deutz engines than they did with the early Ns. One of these dealer pretty much refuses to trade for a Deutz Gleaner. Both have made the statement that if Agco hadn't gone to the Cummins engine, they would have no more Gleaner customers. There are still quite a few late Ns, like mine and lots of 2 series in the area with more each year. Around here, Deutz ruined Allis Chalmers tractors and almost took Gleaner with them. The local salvage yard has had several burned DA 71 and 91 series tractors. Engine compartment fires, salvage yard has no history as to why they burned. But with that said, the dealers are still willing to trade in the tractors. I honestly haven't seen a Deutz engine Gleaner in the local area running, in over 5 years. The local man that had the R60 burn on him said that he missed blowing the engine out 1 day and blew the back 2 jugs, and had a minor fire going when the monitor went off. He very proudly owns an R62. I, as a pilot, looked over the design and designs of air cooled engines decided that the Deutz would not be good in extremely dusty conditions. Mount St. Helens ash destroyed many airplane engines in the era of that disaster. The Volcanic ash is smaller particles than bean fuzz and corn chaff and it plugged and destroyed many engines. Consider yourself lucky. Note that no North American related manufacturer uses the Deutz design in a combine but still uses the design in tractors. That says alot in itself!
