An R50 would be nice step up from currant machine. The small inline 6 cylinder needs a little more TLC than any other Deutz I know of. It needs good fan blade to pump right amount of air and or not wore to point of being out of balance. Operators that like to just start and rev cold engine or shut down without a idling cool down period could have shim sneak out of place from under the jug. This will cause a snaping noise when starting engine and reving engine. This would be snaping noise coming from head gasket leaking compression because jug isn't being held down square. This will also show up as leaking oil at base of jug. Listen for snaping and have blade inspected and if no oil leaks it should be just as safe of a buy as any other machine with similar hours. The 9690 that Kevin talks about has the same series Deutz as the R60 only in a turboed inline six cylinder. That inline six and the naturally asperated V8 in the R60 have been rock solid. Blower blade in these machines need to be in good shape as well. I've seen blades in tractor applications last beyond 10,000 hours while combines very dependant on the abrasiveness of dust in the air. A couple R50s running together in edible bean dust may get only 500 hours out of blade while I've seen V8 blades with 2000 plus hours in good shape. Anyway hopefully that gives you something to look at. The R60 can be quite an animal with it's 228 horse power if the cylinder is set up to flow straw properly. The R60 is a more complex machine as compared to an R50 or machines you are used to. The R60 is for the most part a very refined N series. '90 and '91 R60s would have very similar rotor setup (P3) as R62s. The R50 had the P3 right from the get go. The replacement for the R60 was what was so called the fat 50 project.
