The implement sounds interesting. I wonder about the size of rocks that can be handled and what happens when bigger ones are encountered. I also wonder what happens when the bucket fills up with rocks. Sure does sound like a great thing for some soils. I have heard of 'rock pickers' but I think they are more expensive and may not be designed for compacts. I am curious about the idea of ‘T'ing’ into the loader hydraulics. I assume the unit requires a hydraulic connection, but I don't know if it requires a simple power-beyond connection or if a valve controlled pair is required. However, I didn't think a simple t-fitting in something like the power-beyond line from a loader valve would work in an open centred system. There would be an open line to the sump provided by the PB line and a parallel open centred line provided by the implement. One line would have to be closed before closing the centre on the other line would develop pressure. Something like a diverter valve would work, as would a 3rd valve on a loader SCV (such as I have) or series connection into a PB line (such as the JD rear hydraulics option). I've also heard of things called 'hydraulic multipliers' that convert one outlet into several outlets, but I'm not sure they're manufactured any longer. I guess it's possible that a t-fitting could be placed in a loader lift cylinder line, and the lift control valve could be held open during operation. In theory, the weight of the implement and rocks may create a load on the lift cylinders that is much greater than the load produced by the implement. In such a case, the implement would rotate but the bucket wouldn't move. However, the idea seems a bit shaky. If the implement encountered a high load, then the bucket would move--sounds a little like 3ph draft control. Anyway, these are just some idea on how the hydraulics might work. I am curious how they do work.
