Re: hydraulic tiller for a 425 JD
Deere hydraulic tillers run off a pump that is driven by the mid-pto. The 42inch hydraulic tiller for the 425, 445, 455, run off a pump which is shaft driven and runs off from the mid 2000 RPM PTO.
Well, if your buying a Deere 425 thru 455 and don't want to put a 540 rpm rear pto on, you can still till because you use the mid pto. Still need the 3 point hitch, though.
The pump moves the hydraulic fluid which in turn moves the tiller motor. With the JD hydraulic tiller you can reverse the tiller on the hitch and back till with them. They really dig in better than the conventional tiller.

So, no need for a rear pto. The pump (on a bracket) locks under the tractor and is attached to the output 2000 rpm shaft. Hydraulic lines attached to that, run back to the tiller.
The 3 point hitch is physically tied to the rockshaft, and lift and lowers with the same piece that lowers and raises the mower deck, I believe.
