Lawn Mower Tractor PTO Clutch Warner - 5219-62

The 5219-62 is the Warner supplier number behind the John Deere AM141536, AM134397, and AM136787 - the reference point that consolidates the cross-reference web. Whether the failed clutch carries a John Deere number, another Warner 5219-series number, or the X0383 aftermarket reference, the trail leads to the same clutch. Ordering by the Warner master number eliminates the risk of matching one brand's number while missing another's.

One clutch serves the John Deere X300/X500 series (X300 through X534) and the EZtrak zero-turn line (Z425, Z445, Z335M, Z355R, Z820A through Z850A) - one of the broadest application bases in the John Deere parts world. For dealers and shops servicing the X and EZtrak family, one SKU covers the platform without cross-referencing between model-specific part numbers. The shared Warner architecture means identical fitment, torque, and installation procedure.

Rated at 125 ft-lbs, this clutch delivers the engagement authority to spin wide fabricated decks - the 42-inch to 54-inch configurations of the X-series and the 42-inch to 54-inch EZtrak decks - through thick turf from a standstill without slip or chatter. The rating provides crisp blade engagement through spring growth and wet grass, and supports the frequent stop-start cycling of zero-turn operation on the EZtrak models.

The 1-inch crankshaft bore fits the 20–26 HP Kohler and Kawasaki engines on the X/EZtrak family, and the 5.5-inch pulley uses the offset design that positions the belt plane to align with the deck input pulley - a dimensional requirement of these machines. Installing a centered-pulley clutch causes belt misalignment and accelerated wear. Combined with the CCW rotation and dual belt-width compatibility, the fitment package is complete and specification-correct.
