I find a good deal on a 2011 Sportsman 500 and picked up a Groundhog disc plow, and I think I’m set. I go to put on the disc, and it doesn’t fit. The receiver is a different size than the common 2" hitch. I contacted Groundhog and was told the receiver that comes with the Sportsman is too lightweight to use with the Groundhog, so I’ve been contacting various companies that have ATV receiver hitches. Unfortunately, I’ve not been able to find anyone that has one that will work. I did find something that looked like a coupler (fit into the receiver on the Sportsman) and in turn the disc fits into that. I don’t think it will work – if the original hitch is too lightweight, increasing the lever arm will only increase the torque on receiver. I’d appreciate any ideas. I’m trying to get an old Wards PowrKraft welder going, so before too long, I’ll have to make my own.
