Popular John Deere PTO Clutch Replacement Paths
Common John Deere PTO clutch replacements include AM122969, AM141536, AM119536, GY20878, TCA20484, TCA21167, TCA21168, TCA19813, and TCA20380. Always confirm the original clutch number before ordering.
John Deere STX38 Yellow Deck vs Black Deck
The John Deere STX38 is a known fitment trap because yellow deck and black deck tractors use different PTO clutch paths. Some black deck applications also split by serial number, so do not choose by deck color alone.
- STX38 yellow deck: use the AM100979 PTO clutch replacement when your original clutch number matches AM100979, AM115090, AM118969, AM122969, or Warner 5215-35.
- STX38 / STX46 black deck, serial 270,001 and higher: use the AM121972 PTO clutch replacement when your original clutch number matches AM121972 or the Warner 5217 clutch path.

John Deere ZTrak PTO Clutch Fitment
For John Deere ZTrak mowers, deck size and serial range can change the correct clutch. Do not choose by model name alone. Use the original clutch number when readable, then confirm serial range, deck size, bore size, pulley diameter, rotation, connector plug, and anti-rotation setup.
Common commercial ZTrak paths include TCA19813, TCA21167, TCA21168, and TCA20380. These are separate clutch paths and should not be treated as universal replacements.
