Combines duals or 30 5 s

Duals are generally for extra width to help stabilize the machine with wide heads. Also , to put the tires between the rows with corn heads. We run 30.5's and like them. I think they get around better than dual 18.4's. Neighbor has an R-60 with duals and I can go places he can't with a 1480. A lot of that could have to do with difference in weighting of machines, though. I know some JD's are having wheel problems with duals and a couple of IH guys are having problems breaking wheel bolts. If you're concerned about flotation, I would just look at a wider single tire.

Id go with duals weve been running our 2388's on duals for a long time now and weve been very happy with the traction and how the combines run with them on on a side note everything we do is no-till but on the ocasionall conventional ground weve had no problems running kinda figure we will never do tracks again. we'll just stick with duals

We have a 2388 with duals now but had a 2188 with 30.5 before. From our experience the duals will give you a more stable machine floating over bumps where each single tire absorbs more of the uneveness than a 30.5 will. It's quite noticeable. As far as mud goes, I don't think there is much difference between them. We'll never go back to singles.

Cousins just went from duals to the 55 inch wide(I think) flotation tires and a wide metric on the back. They say they like them better than duals. I'd like to try them, but don't like the price tag! Chads

55" wideIJ I think the Firestone 76x50-32 is the widest one on the market right now at 48.6".

For ridge till you need to have duals or you're defeating your ridge till purpose. Duals are fine, if you never have to take those of for hauling on a trailer, etc. and want to spend the extra money. If you cross a pivot track in a 45 degree angle you will notice it 4 times instead of only twice. Duals put more stress on final drives, especially if they are not factory. The factory duals with axle extensions are much stronger and much more work to mount. I had a Kirschner dual break off this fall. For mud I think the new 800 or 900 singles are just as good. They also steer nicer in dry conditions. In wet conditions the duals follow the corn rows better, especially in ridge till. That's my experience from operating both for the last two years.

You're probably right, for some reason 55 inches was stuck in my head. At 50 inches that's still a heck of a tire! Chads

How about saving 100's of thousands. 15 thousand will go a long, long way to restoring even a pretty wore out IH combine. Our old 1480 with 5500 hrs now gets by on about $3 per acre per year, and very few in field breakdowns. However, McCormick is apparently doing the impossible with the tractor line. CaseIH said their cost structure was way to high to be competitve, but they are. One of these machines from McCormick would likely be more affordable than you think, and a 60, or especially a 66 is not a small machine. Chads

Having had 35x32 and now 18x42 duals I would never go back to singles. They ride so much better and if it gets wet those two small ruts are much easier to close than that big old sow hole a big single leaves. Plus you can replace duals for less money than the big singles. They don't get the stubble damage and your flex header control will work less_better. The only downfall we have seen is transport width. The only tire that might be better in mud would be the logger tires and they are big $$$$.
