The Xtreme X0325 electric PTO clutch is engineered as a direct replacement for OEM part numbers John Deere TCA12522 and Warner 5218-91. It features a 1.125-inch (1-1/8") crankshaft bore and a 6.3125-inch (6-5/16") machined pulley diameter compatible with 1/2-inch or 5/8-inch belt widths. The unit operates at 12V DC with a clockwise rotation direction and delivers a torque rating of 205 ft-lbs. Construction incorporates Cool Coil technology for thermal management, a heavy-duty FatBoy series upgrade for increased durability, and a replaceable pulley bearing design to extend service life. The pulley is billet machined to Xtreme Precision standards. The integrated wire harness utilizes a 3-layer Xtreme TOUGH construction for water-tight and impact-resistant performance. This clutch fits John Deere ZTrak 737, 757, 777, and 797 zero-turn mowers.
