I purchased the hyd. cylindr from Surplus Center, which is advertised on TBN, and then bought the hoses made up at Napa. It was around $175-$200 for the setup. I wouln't have a tractor without a hyd. top link. It works great for boxbladding and makes it alot easier when hooking up implements. You will need to figure out the size and length cylinder you will need. Make sure you get the right type of eyelets at the end of the cylnder. My first hyd. cylinder was from a steering cylinder of an old JD combine. I bought about 2 feet of hoses with the Pioneer fittings X2 and assembled it together. Worked like a charm. Good luck, I just bought a D40 and am putting rear remotes so I can use my cylinder.
