Does anyone know a source for a good heavy swinging drawbar? My 3710 didn't come with one. I bought one at TSC and found it to be junk - bent and then broke within a few weeks of hauling trailer loads of firewood. To haul the trailer I designed and built a hitch that goes on the 3pt, but now I'm getting into haying and I need a swinging drawbar for pulling implements. Any suggestions? Thanks!
