on an 07 3,000 pound trailor single axle 5 x 10. It broke and turned sideways and ripped the tire up on the side wall just not all the way through. I only put 2 walk behinds on at once a 54 20hp and 48 17hp. maybe 2,000 pounds max if you add the other **** like racks and so on. I wish I bought a dually. Lots of problems with this one. Is this normal because their are no shocks?
