Dieselshadow asked me to post some photos of my Fit Rite hydraulic top link on my 2720. I only have a few photos at the moment. Please note, my first top link had some clearance problems due to the fittings being located on top. Brian made me a new cylinder toote-sweet with the connections on the side and it works perfectly. Unfortunately I did not take any photos of the new cylinder and I had to remove it for winter as I needed all four of the hydraulics ports for my 54" snow blower.
I installed the JD rear hydraulic port kit which basically just provides hoses and a mount to re-route the side ports to the back. Since all I needed was a single set of connections for the top link and routing and clearance was a bit tight behind the wheel, I only installed one set of hoses.
I wish I had the 3rd SCV so that I could leave the hydraulic top link connected all the time because it is MACK DADDY. It allowed infinite control of my boom pole, makes adjusting the pitch of my rear blade a snap, it allows for easy control of my 3PH Pallet Forks and I even use it with my Land Pride quick hitch for fine adjustments. Since putting the OEM top link back on I am really missing the hydraulic link.
