I notice that you have installed a lever on the left side of the steering wheel, looks like it is linked across the steering column to where the lever would be for the quick attach circuit.
I thought I have pretty much read all the threads on this board, and haven't run across a discussion of this mod before; the only ones I have found about adding or modifying hydrualic circuits were the ones for the electric selector on the joystick. I stalked you through your past posts and found the picture above, but didn't find a discussion of how you made your mod.
Any of the parts stock, or is it pretty much home-made (I am guessing you are pretty handy with the stinger based on the ROPS and pond rake in the picture).
Looks like a pretty good idea, since the quick attach lever is definitely one of the features I like least about my PT; it is a royal PIA to use it to curl the minihoe or operate the 4N1 bucket.
I think I would just as soon run another manual hydraulic circuit for those accessories (minimize the number of connections/disconnections done when changing attachments). Unfortunately, not being handy with the stinger, such a mod is probably a bit ambitious for me, and I will probably have to go with the electric selector valve idea.
EDIT: never mind, I found the thread with the discussion of the mod:
