We traded off four of those with about 1100 hours on. They all had holes blown through the top rotor housing. They needed new concaves, tines, threshing elements, rotor housings, fountain augers, shoe auger bearings, feeder house floor, new supports for feeder lift cylinders, maybe final drive overhauls since one broke, pieces for the clean grain elevator, etc., maybe $20,000 worth of parts per machine, just for a rough guess.
