Mtd Yardman Hydro Gear Hydrostatic Gearbox

MTD Yardman Hydro Gear hydrostatic gearbox. I saved the gearbox from being scrapped as it may be of use to someone. I didn t remove it from the tractor but a friend did was removed due to a half shaft , unusually, breaking. I understand it was working till this point. The shaft could be welded or a new one fitted if keen enough to strip it.I believe it was removed from a Yardman HN5200 but with a bit of research may fit other makes or models.The numbers on the label are 618-0398A 331-0510.Thanks for looking.
