For me because I am in FL the Super with a XR7 is great so I will just update the mower as needed and as I see fit. I do not remember on this site who it was that had the back engine plate cracked twice but those are the only major failures I know of and that sounded screwie to me? The problem I have with the Super Z is not enough torque for hills,the XR7 could dispearse the clippings better for sure and I would like bigger wheels for traction on slopes. The throttle cable is cheesie as well and breaks, Handles for hydro engagement can bend,splindel shafts bend to easy but are easy and cheap to fix. Seems like the oil capacity is to small for Hydro system? but all this stuff is easy to update and other than those complaints I love the mower especially the way it cuts short at 15MPH and leaves no stingers and the XR7 can be run into practically anything at 15MPH and it would just take it on the chin. How is the new Super better and worse?
