thank you for your help. As an experienced plow man. i've tried everything pracitcal that i can think of. The plow draws at a left angle to the tractor and the front plow cuts to wide a furrow(28in-30in). The wheel setting is correct according to the operators manual that I have, but the manual is for a newer version of that plow. I have threee of those plows and the hitch is diffrent on every one of them.
