There is a difference in the laws in PA for hauling commercially, which includes your own business, or private/personal. In PA, you need four separate chains for the tractor, each capable and rated for at least half of the tractor weight, and each connected to the tractor frame/axle separately with separate trailer connection points. Billrog's picture above shows two straps connected to another just going around the brush guard. If one strap breaks, you lose all the front tie down. Therefore the reason for each to be separate. Kind of dumb but the fel bucket is to be chained down and if you have a bh, the bucket has to be chained down. The laws may have gotten crazy but maybe if followed, I wouldn't have had a bulldozer laying on it's side in my front yard. If you have any hauling questions, just call the state police in your area. Around here, they're always willing to answer a question or advise you how to stay legal.
