Is AM119683 the same as AM121972?

No. AM119683 and AM121972 are separate John Deere STX clutch paths. AM119683 is associated with earlier STX38 and STX46 Black Deck models with serial numbers 270,000 and lower. AM121972 is associated with later Black Deck applications. Do not choose by model name alone.

Does this replace Warner 5217-35?

Does this replace Stens 255-511?

Yes. This listing cross-references Stens 255-511 when matched to the John Deere AM119683 / Warner 5217-35 clutch path.

What bore size does this PTO clutch use?

This clutch uses a 1-inch crankshaft bore. It will not fit a 1-1/8 inch crankshaft.

What pulley diameter does this PTO clutch use?

This clutch uses a 5-3/8 inch pulley class, commonly listed around 5.345 to 5.375 inches in aftermarket catalogs. Always compare the pulley size, belt profile, and product photos against your original clutch before ordering.

What rotation does this clutch use?

This clutch uses counter-clockwise rotation, commonly written as CCW, when viewed from the pulley side. Match rotation before installing a replacement PTO clutch.

What are common signs of a failing PTO clutch?

Common symptoms include mower blades not engaging, the PTO clutch clicking but the blades not spinning, slipping under load, intermittent blade engagement, a burning smell, or blades slowing down after the mower heats up. A worn PTO clutch coil can work cold, then weaken after 10 to 30 minutes of mowing.

Can PTO Direct USA help me confirm fitment?

Yes. Email support@ptodirectusa.com with your mower model number, serial number, deck color, deck size, original clutch number, and clear photos of the old clutch. Include photos of the pulley, bore, wiring connector, clutch label or stamped number, and anti-rotation bracket area.

Removal warning: If your old clutch will not slide off the crankshaft, do not pry or hammer against the clutch body. Read the PTO clutch stuck on crankshaft guide before removal.
