Your not likely going to get many that openly say they haul overweight.
It can be deceiving just looking at the rigs, example bobcat T650 wights in around 9500lbs so that might meet restrictions but a T650 with roller suspension is like 10400lbs so it wouldn't.
Its not that hard to get the proper license and can you afford to be caught without it? Likely will need it down the road when you upgrade machine or get more so you might as well just get the proper license.
Plus the fact if you get in an accident (maybe not even your fault) and insurance finds out you were towing on overweight load you can forget about getting anything from them.
Truck, Mower, Trimmer, Blower.....same as everyone else.
