Anybody have any experience mounting a Digger Universal hitch to a Yamaha snowmobile (96 Vmax XT)...the rear grab bar is circular metal wrapped in plastic, being that it's circular metal drilling holes in it isn't my first choice to mount the Digger, due to the small dia. not sure it's even possible. Thinking I'm going to have to mount it to the lower portion of the aluminum snow flap mount unless someone has a better idea...PM's and pics welcome!!
