yup I got the one from harbor freight on my TC18. I love it. Only problem is that for best results, you likely have to modify implements to make them all the same with regards to the vertical distance between lift arms & top link. Also the "mast" of the implement needs to have clearance for the hook to get under the top link pin. If you are just starting out collecting implements, get the hitch now & make sure all future implements are compatible.
Lastly, the pto shaft may come up short, but you can get an extender for $20 thru agri-supply or probably TSC or your dealer as well.
See attached for me destroying my counterweight to make it work.
