Man you got an awesome deal. I had a vendor price that same setup at $275 right after I was checking on auxillary valves to set up my 3240. I ended up buying 2 valves off ebay for $40 each shipped with handles and brackets.
I cut and welded the deck lift handles to make them fit the other slots in the cupholder rather than buy separate aux handles.
Lol, everytime I see that cylinder I'm shocked at its size. Here it is next to a steering cylinder ith one of the 1" pins next to it. Thing is insane. My lift setup will be similar to this. https://www.mytractorforum.com/119-home-made-tractors-implements-accessories/131383-front-scoop.html
