  1. are you allowed to haul oversize permit loads as well as extra attachments to the permitted load as well as other supplies on the same trailer ? for example I know you can remove the blade off the bull dozer and haul it with the dozer to get the width down the blade is oem equipment but if the blade is narrow enough to remain attached can you haul root rakes extra rippers ect ect . appreciate a response I’m almost positive you cant haul anything with it other than original manufacture equipment .

    • Brian so sorry for the delayed response as we lost you but now you’re found. So for the rest of you out there Brian is correct. A load that can be reduced must be reduced with special exceptions made for dozer blades but not the extras if it causes the load to be over weight or over-dimensional. Great question, thank you!
