I think you are fortunate because you are young an not color blind. Alot of us like to run what our families have been running because we are knowledgeble of those machines. This site should help you make a decision no doubt, just read the posts and ask questions about a machine that you maybe interested in, and help is just around the corner. Myself I would recommend a R series rotor, because of the rebuild ability of them, simplicity, and tremendous performance for the size of the machine. It would probably be better if your looking at one with the cummins engine, because of the cost to rebuilt the deutz (excellent engine but expensive to rebuild when it comes time). I would recommend having a Gleaner mechanic looking a machine over before you purchase it, just for a second opinion. labor is not cheap today. You can wrap up alot of money in a hurry with any machine on the market. From what I have read also the 8780 or 8780XP is a great performer also, but again Im on the AGCO side of the fence. The Massey rotor appears very simple and has a very long rotor which should give great seperator performance. Just keep asking questions, thats what we are here for!!!!

The N series before 1982 are the problem machines. For what they could and were expected to do they weren't built heavy enough or powered well enough. The 1982 Series 3 had most of the updates in and were built heavier to handle the loads. The 1982 change from the Roosamaster system to the AMBAC fuel system made a huge difference in power and engine reliability. The later N also had a longer throat that is capable of using new heads. The AC R series is basically an N with all the fixes in. The DA R series was modified and has less parts and in some areas loses some capacity over the N. All machines 1982 forward are great machines and very reasonably priced for the capacity and grain sample. Normally once you go rotary you won't go back to conventional.

R series! 8780! slow down a bit turbo i have student loans to pay for. thats why i'm looking at these older machines, i've looked at the N combines on dealers websites but don't really think i want to go through a dealer because the ones around here at least, keep their skinning knives sharp. what i was thinking about doing was finding one at an auction, anybody have any idea what a later model n7 would go for at auction, at the end of march there is a big 3 day consignment close to here and already there is an r72 sitting there but all i can do is dream right now. I have heard good things about the l2 and l3 as well can anybody tell me about themIJ Silver Shoes you said to have a gleaner mechanic look it over, can you tell me what to look for, and should i have a break down how much of it could i do myself. John when you say throat do you mean the feeder house, i've just never heard the term throat yoused before. one of the good things i've heard about gleaners was their simplicity. is this so with the Ns as wellIJ all the combines i've been around are conventionals my grandads 850, my uncles 7720, and my little 82 massey. its kinda funny listening to my uncle and grandpa go back and forth about whos machine puts more out the back while any one with any sence knows my combine does the better job of the three of them so what if its not as fast. so john why do you say that most don't go back to conventionals, i admit i've never really been around a rotary but i like the idea of the return grain going back into the separator. an as far as i know a rotary doesn't do this or does it need to. well i think i asked about all i wanted to know about thanks for posting Red

The two conveyors chains and their bottoms to the rotor like to wear. Open the panels around the rotor and look at the overfeed augers and bearing as well as the cage and bars themselves. The accelerator rolls under the rotor are very important and the condition and their bearing at both ends need to be checked. No light should be seen between the rolls. The connector between the engine and hydraulic pump age, it looks like three motor mount bushings and they will stop you dead where ever you are when the fail. Check the main clutch shaft(runs from one side of machine to the other) for trueness. Hard stops(plugs) were known to bend or break them, bearings on this shaft are VERY important. The half shafts are know to develop problems with age, (left front under the cab, clutch attached to it). Check the 2 speed gear box on the rotor for play or leakage. Some of the alternators used on the N series were troublesome, use as much current as possible and see if it the light comes on or gage drop too low, sign of alternator problems to come. I believe that is why he said have a dealer look it over, knowing what and where to look when unfamiliar to the machines can be quite a task, once you know the Gleaner rotary it is a very simple task. Checking my N6 is actually easier than checking over my former conventional machine.
