Overview

This aftermarket 917-3403 electric PTO clutch is a replacement for 717-3403, 717-3403P, 917-04180, 717-04180, and Warner 5218-6. It is commonly used on older Cub Cadet garden tractor and super garden tractor applications, including the GT2186, GT2523, 1863, 1864, 2086, 2176, 2186, 2206, and 2284 clutch paths.

This clutch is built for applications using a 1-1/8 inch crankshaft bore, 6.00-inch pulley, CCW rotation from pulley side, and A/B belt profile. Match your original clutch number first, then confirm bore size, pulley diameter, connector style, anti-rotation setup, and deck belt path before ordering.

Important: This is not the same as the 1-inch Cub Cadet clutch paths. Do not substitute this clutch for similar-looking 1-inch bore clutches unless the original part number and physical specs match.
