My mower has the factory “hitch” on it. This is just the short lip that allows me to hook anything that used a vertical pin to the back. I’d like to either put a 2” ball on it or maybe even a 1 1/4” receiver on it so that I can remove when not needed. That way I can put the hitch kit on my small dump trailer and not have it rattle around as much when I’m in the yard. I don’t see anything online that is made to fit my mower in the way of a receiver mount and the holes in the factory hitch are way to small to drop a ball through it. Any ideas? I’m sure the factory hole could be drilled out, but I have nothing that size in the way of a bit.
