| I bought a new machine in 2004. All machines have the same threshing and separating units. The difference was in the options and horsepower. A neighbor had a 9860 then and had problems in wheat with the air filter always plugging. He also said it liked it's fuel. However, he traded two years ago for another 9860 and this year has a new 9870. I suppose John Deere has addressed the air filter problem on the older machines by now. I would not buy a 9660...less horsepower, smaller grain tank. less options. Also I think the feederhouse gearbox is not as heavy as the others. What I did was buy a 9760 and added all the options so the only difference in mine and a 9860 is the engine and the decals. I am very happy with this machine. I would recommend a 9760. If horsepower is a problem, you can always buy a chip, which I have not. The most important advice I could give you is buy one with the 300 bushel grain tank and the high capacity unloading auger, you won't regret that. Wheat is the hardest crop to harvest with any machine. I would recommend the small wire concave for wheat. I use the standard round bar for soys and corn and they go through the machine like water. | |
