The 38 inch deck on my Cub Cadet 70 did not sound right when in use this weekend. A close inspection revealed a slight wobble in the center pulley. We removed the deck, and the center pulley revealing a break in the key way located on the spindle. I cannot locate a parts manual for this deck, it is needed so I can remove the spindle properly, and locate the correct part. Any help locating a online manual or diagram would be appreciated.
