| Never had any major issues and all we've had are 2wd combines.
Used to run 30.5's on the 9x00 series JD walkers, went to 66x44 floaters on the 50sts with the skinny rear tire, and now are on 20.8 duals with an oversize rear tire. I think a big rear tire is key, the front of the machine never really digs down as much as the rear. Have gotten stuck a few times in 2009 when the cornbelt had a miserable harvest and we broke through 6" of frost in quicksand, but thats a rare and odd combination. | |

How important is 4wd on a combine?
