Haven't tried the Deere chuck wagon yet if we have trouble it will likely go to hydraulic as well. We have put a hydraulic unload on our Roorda wagon after fighting the pto and chain trying to unload. It was fairly simple with two hydraulic motors and double 60 chain with sprockets. Run the hoses to the variable speed control and hoses for the tractor. Works fairly good just a little slower than pto and you will need a tractor with decent hydraulic capacity.
