Hi west illini. I have some pictures posted on farmphoto.com of my track setup for a sprayer. If you want to look at it, it is in the sprayer section under "unfinished sprayer chassis". Its a red chevy up on a track frame I built. It may give you some ideas if you were thining about doing it yourself. Its setup so there is no stress on the drive axles, much like you're concerned about the finals. If you drive the tracks with small enough sprockets, you could potentially get away without the final drives all together. I've been thinking about having four wheel steer on the combine like my track chassis to be able to turn at the end of a windrow without backing up. If you were to put an entire subframe under the combine, you could easily make it a quick change setup. Also with a subframe, you could extend the length and not worry about hitting the tailings elevator. I would put four tracks on it and put the front tracks a little further foward to distribute a little extra weight to the rear. Then put the same size tracks on the rear. This way you would really have a low ground pressure setup. If you do like what I've done and want to see more detail pictures, I'll be glad to send some. I would also share any info I found on tracks and undercarriage design. The tracks on the pickup are metal inbedded tracks like what is used on a mini excavator. They're a little cheaper and the undercarriage is easier to build, but the tracks wont take high speed very well.
