It came with the lawn mower I purchased so I wasnt going to argue about taking it. I cant see a model # or a brand name or anythign on it. Which probably means no serial #. Is there anyway I can figure this out, it looks nice so it was almost definitely made by someone int he business not just a homeowner welding metal scraps together. I also need to know how can I get this licensed? My wife had purchased a trailer from a family friend and the DMV of WI told her if it didnt have a VHIN # or serial # it could not be licensed. Will I be in big trouble if I use it to haul around my mower? So do I need to go out and purchase a big trailer to tow this mower around now?
