tb,
Not to make this obnoxiously contentious, but, can you make a mark on the ground and proceed straight out from it, immediately turning the wheel sharp? After the tractor has returned to a position 180 degrees from the start, you should be able to establish the uncut circle. Somehow, I expect it has to be less than the country mile you describe. /forums/images/graemlins/confused.gif Please help enlighten us! /forums/images/graemlins/tongue.gif
