Thanks for the info! I did some measuring and if my calculations are correct, reversing the drive tires from left to right should bring them out enough to straddle 4 30" rows (about 94")! I guess I might be answering my own question here, but if I were to select a "stalkier" hybrid of corn, I would be able to raise the cornhead high enough to leave a decent amount of stalk standing. I agree that it doesn't make economic sense to work the tar out of an almost $200,000 (Canadian dollars, relax tbran) combine, just for the sake of stover. Besides, it's nice to leave a little residue on the field, anyway! Thanks for all your help. I'm quickly finding this forum to be far more helpful than any owners manual out there today.
