Add me to this list. I was using my 4710 And MX-6 cutting nothing more then tall field grass and heard the RPM shoot up. Yanked the tractor to idle, looked behind me and saw the stump pan and blades lying behind me. The main shaft sheared right in two. Clutch discs were fine and not frozen. I assumed I could replace one or both of the planetary gears in the gearbox but found that was not to be. Seems John Deere changed the ENTIRE setup on this mower and now you can only buy complete replacement gearbox on down. Cost about $1600. Gee......I wonder why John Deere changed the entire gearbox if they had no problems with the old style??
