What do you want to know, I have one on my 555dtc, but it is a 3pt hook up with brackets on top to beef up the top link. I can tell you it digs ok, lacks for power a bit, but we have not been unhappy with it.
We run ours off the remotes. Ours is 3 point hitch so no frame. Longer 3pt arms needed for 3pt mounting. IIRC the manual states the 3 PT linkage needs to be removed to install subframe and/or backhoe. No provisions that I see to add a thumb. Just to give an idea it was 7k new.
Anything else let me know. I think I have the manual somewhere.
