First off, a 3 point for a 140 is entirely different than one for a 318, since one is a closed frame tractor while the other is an open frame tractor. With the right skills, tools, patience, time, and knowledge, anything can made to fit.
Also, keep in mind, that the older 3 points were category 0, while the X series had limited category 1 hitches.
I looked at those online there.
My main reason for asking about the 140 3ph is, I got one that's been completely rebuilt and powder-coated, ready to go.
I guess I'll sell it and use the funds to get the Ruegg.
You don't happen to know anyone looking for a nice hitch by chance, do ya? LOL
I bought the thing from a fella on eBay about 5 years ago. It come from somewhere in the Eastern U.S.
