Combines Duals on rear of NON 4wd IJ

You don't need duals, just big radials. We run our rear tires at 6 psi and they never fall in. However, we have the 4WD to take the extra loads. The dealer in Holdridge Nebraska makes a heavy duty 2WD rear end that might be able to handle the bigger tiresIJ It probably all depends on the spindles. Maybe you could use JD spindlesIJ They look really heavy.

Do you already have the wheels and tires to use as dualsIJ If you have to buy them, I think you should get them a little smaller in diameter. The spindles on the older machines dont like too much leverage and they're quite expensive. First thing I would check is the clearence between the tire and your tailings elevator. Turn the wheel all the way and measure to see if you have space. If its that wet, well, you just have to do what you have to do to get the crop in. If duals are something you think will get you in the field, then go for it. Its what you have to do.

Been there, done that. From my experience it really didn't help. In fact I thought they were a detriment, always balling up with mud and made the combine hard to steer. When the backend did fall in then the only way to get out was with a tractor and chain. Before, at least I could back out of a mudhole. I went to larger single tires with much better success. No matter what you do there is always going to be a mudhole you can't get thru. A friend put a mudhog on his 1660 and the first day out with it got stuck twice and had to be pulled out. Don't know where you're at but when it gets that bad we harvest what we can and then wait till the ground freezes to finish.
