I"ve got a beloved "71 JD4320 that came with a top link on it"s 3-pt that ends in an upside-down hook-thingie** for attaching to implements. It looks like it was stock, so I assume at one point it was a standard 3-point variation that Deere sold back then. Possibly, some form of early quick-release mount than never became a standard.
I"m interested in figuring out what this style of top-link connector is, and what the "correct" specs are for it, and what its original purpose was.
Anybody know what this style of top-link was for, and what it"s name is so that I can look up information on it?
**Better description of hook-thingie: It as a big cast-metal piece on the end of the top link that is designed to be placed downward (IOW, the open end is on the bottom) onto a roughly 2 inch diameter hitch pin (much larger than a standard top link pin) When you lower it down, a small piece latches underneath to secure the implement, and there is a top lever you pull to retract the pin and release the top link.
