I've probably answered my own question, since I can't find one anywhere. But it got me thinking: why can't a trailer ball be pinned on instead of with the nut and lock washer? Of course the later is more secure, but I'd like to pull my little log splitter via the drawbar with the LX, unhook it at the work site, then use the drawbar for pulling chain/strap. I could buy another drawbar and mount a ball to it, but it sure would be nice to have a ball that could mount with a pin like my chain hooks and clevis hooks.
