There's a lot of threads on this, and I've read a lot of them. I ended up with a Rankin brand Quick Hitch for my JD 3320. It appears to be the same as the Worksaver from the link above. I'm sure these are all made by Speeco and rebranded for various parts of the country. My JD dealer doesn't carry the iMatch and instead carries the one I purchased as it is more flexible in terms of what can be hooked up to it. There will be implements that do not fit onto any quick hitch and if I were to do it again I would look closely at Pat's Easy Change. To some degree it depends on what you want out of a quick hitch- if your goal is to back up and drive away with a new implement without getting off the tractor, Pat's is probably not for you. If you want to be able to hook up all your implements, with ease, but still may need to get off the tractor (which I usually do with my quick hitch anyway) then Pat's may be the way to go.
