If your loader valve has "power beyond" then it is pretty simple. Tap into the power beyond ports on the valve, run pipe or hose to the rear of the tractor where you'd install 2 quick connects, tap a valve in those lines in a convenient place between the power beyond ports and the quick connects and there you have it. Some brands actually sell a kit that you can add to your tractor and do as a user install. Rough guess on a dealer installed set up price, $500. Could be as high as $1000 if you don't have power beyond or you want to do something a bit fancy. Prices would include the hardware and labor. I never priced a kit, but I know some are available, although they are tractor specific.
