I finally found a nearby belly mower with the hydraulic kit; the mower only has 12 hours on it. In contacting my dealer he was very willing to install it and finally deliver my tractor; however, he has since learned that part of the holdup is that John Deere has improved the belly mowers. The new model is purportedly heavier and better (they are also now green in color rather than yellow). The new model will end up being the same price and so have decided to wait for the newer one.
