How to Confirm Fitment
The most reliable way to confirm compatibility is to match the OEM part number stamped on your original PTO clutch. If the number is worn or unreadable, compare the 5.35-inch pulley diameter, 1-inch crankshaft bore, CCW rotation, integral connector style, and anti-rotation slot or pin position before installation.
A matching bore size alone does not guarantee fitment. Similar PTO clutches can use different pulley diameters, torque ratings, connector styles, and mounting profiles depending on mower brand, model, deck size, engine package, and production year.
