Hi! I'm new to the site too. I have had JD lawn tractors since 2004 and have replaced one Tuff Torq K46 and am now on my second. This one I got as a project because the trans was slipping. Took it apart and found that the pulley spline was stripped as well as the shaft. I was expecting to have to replace the pump and motor like most have done. I can't seem to find a parts blow up for the goofy thing. I found a bunch with the readily available parts but none showing the shaft and number I need. Any ideas would be great. Links if possible.
