That's one impressive bucket. I sure like the way it separates the clamping function from the bucket rotation. Not being able to separate those two motions is the downside of a traditional BH thumb. Your's seems like a better way to do it. I hope you are patenting some of these designs.
Also noticed that the Aux. Hyd. outputs changed sides. And that reminds me that I wanted to ask what your preference was for size and quick connector type. On the JD310 those aux connectors are dash 12 size - which is 5/8" hose and fitting flow diameter. Yours look like a similar size.
