Neat item, but it is not a new idea. Back in the mid to late 1950's International Harvestor came out with what they called "Fast Hitch". It was the same concept but a heavier duty design.
Their's involved a 1" thick tong added to the implement that came to a spear point that had a square notch cut into it, that hooked into a receiver that had a spring loaded latch.
I had such a hitch on my 1956 Farmall 100 which was a Farmall Super "A" Tractor with a Farmall Super "C" engine in it. For the Framall 100s, 130s, and 140s they had a single tong quick hitch receiver. For the larger Super "C" Tractors they had a double tong Quick Hitch arrangement.
It was very handy to use just backing your tractor into The implement tong, hearing it's quick hitch lock click then driving off with the implement hooked up without leaving the tractor seat. I had a small rope on my receiver lock so that I could drop the implement and unhook it without ever leaving the tractor seat.
I could never understand why this type of excellent quick hitch design did not flood the market and make the previous old school dinosaur 3-Point hitch a thing of the past.
With a quick hitch you did not need the center sway bar link like they used on the three point hitches. The tong supported all of the implement weight and kept it from swaying side to side. It looks like this one will spark new life into a quick hitch set up.
