You were just too unlucky in the end. I pulled a pulltype combine with no flags, signs or anything else 375 miles through Wisconsin, Illinois, & into central, Indiana. Was 1.5 feet over the legal width, was seen by probably 20 - 30 police cars, & never stopped. Young guy trying to make a name for himself interupted your day it sounds like.
One thing You could have done; but wouldnt be my first choice; possibly remove the gangs, & load them in the truck, Or strap them to the top of the disk frame. Depends on the disk though!
