Can you, sure, but theres a few things to consider. My experiences are with scrapers on the road are in ohio. I belive the requirement for permit is going to be based on weight and sq inches of tire in contact with the ground. That being said, if you have a truck in the lead and a truck following you shouldnt have any problems. If the job sites were less than a few miles away we would run our Terex Ts 14s and Cat 627s down the road. The 627s were always a pain as they are pretty wide. The 14s were down right dangerous, as you had to have the throtle wide open to turn. Also the only brakes they had were the big steel thing between the engines. We backed off on roading them when we had an operator take out a bunch of mailboxes with the draft arms. This is where it got interesting, because our operators could not move them so we called the lowboy. The driver would get there, park his truck, shut it down, fire up the pan and drive it down the road. In their defense getting these things on the trailer and chaining them down. We had a scraper trailer for the 627s, worked great, but in order to be legal there had to be an ungodly amount of chains on them. Took about an hour to hang and bind the chains.
