Btw that hitch did not work. The lift rod was way too far out on the lift lever. Took three men and a little boy to lift the implements. I moved the lift point about 1/2 the way in and it works fine.
The only problem with a ball on the hitch is that without a positive stop the tongue of a trailer will slam forward and up upon braking. Not stable on a 7000/700 series with its cable lift but could work on a 300 series since there is a solid link between the rock shaft and the lift lever if the slide feature were eliminated.

The up/down movement seems fine. I added the stop bar on it so it won't slam forward. All seems lined up good. The rains have stopped so maybe I'll take it out and try moving something with it soon.
