Ed - Out of the nine Gleaners we have bought over the years, ranging from a K to an R52, we have owned exactly one new one, an F3. All the others have been preowned. We usually try to find a good, late model with 300 - 600 hours. We very seldom have any breakdowns that can't be attributed to neglect or abuse by a previous owner. On the last machine we had before our current 52, we had to replace the rear feeder chain because, believe it or not, the dealer we bought it from did custom work and continued to run it after the chain had jumped a cog causing it to run crooked. Also had trouble with the wires coming apart the powered the main separator clutch. When we asked the dealer about that, he admitted to turning around in some tall brush on the end of a field and tearing the wires loose. Instead of fixing it correctly, he spliced them back together and we ran into trouble several times after until we replaced the harness. The only trouble we had with our 52 this past fall (our 1st year running this machine) was with the open gears that run the accelerator rolls chipping teeth. There again, it was a previous problem that wasn't fixed correctly because the gears on our machine are actually from a 62_72. We have yet to get to the bottom of what is causing that problem but intend to before we start another year. Obviously, the previous owner just replaced the gears without trying to find what caused them to go bad. It is very possible, or probable, that the previous owner(s) of your machine neglected to maintain it correctly and you are having to pay the price. Every maker has it's lemons but I don't think you should blame Gleaner. Just my 2 cents....
