I have the clutch pack you need if you still have the mower? I had the same problem and made some myself, and have a few extra setsHi there,
I have a Craftsman 12.5 HP 30" Riding Mower (944.601380). which unfortunately the the drive stopped worked on basically the clutch plates broke. Cross referencing part #s the actual component is discontinued. Part I am looking for is #441097 or 532441097 - Plate Clutch Drive its called, which is #59 on blow up diagram.
Looking to see if anyone has any ideas or help on how to tackle this and potentially find a replacement that would work.
