The Xtreme PTO clutch for John Deere mowers delivers better performance and higher reliability than stock clutches. This clutch features a CNC machined billet pulley for quieter and smoother performance at fast blade speeds, while increasing overall strength and stability. The replaceable FatBoy pulley bearing is a massive upgrade, adding durability to the clutch, while making repairs simple. Designed for long life, Xtreme bearings use a blend of high temperature grease and harder races to minimize wear. Stainless steel brake rivets hold the entire clutch assembly together, adding both strength and safety. Xtreme clutches also use a “Cool Coil” to run 20 percent cooler than competitors, with a composite coil that runs around 175 degrees Fahrenheit.
