Interesting, I also recently had a weld failure on my Landpride T&T top cylinder. I emailed Landpride and they said they hadn't been aware of any such failures. I ended up just re-welding it so that I wouldn't be out of commission too long.
Built a no-weld chainsaw mount out of parts I had lying around. Uses beam clamps, aluminum angle, 80/20 aluminum extrusion and the scabbard from my old Husqvarna saw.
Not to change topic, but I've been looking at those for making it easy to hook up a 12V external fuel pump to my tractor for refueling. I would like to hear others that have used these and their experiences.
Take this for what its worth... I just emailed my dealer yesterday asking the same, since I'm waiting for a particular tractor he's ordering, his response was "Kubota extended terms through the end of the year."
