The Chelsea 447 Series Power Take-Off Assembly, part number 447KWESX-A5XK or 447KWESXA5XK, is a 6-bolt mounted PTO engineered around a one-piece input gear with a space between its two sets of gear teeth. That gap is what sets the 447 Series apart: it eliminates internal interference problems at the transmission PTO aperture where adjacent gear clearance is tight. This unit shifts via wire/cable mechanical actuation and delivers a 1-1/4" round output shaft with keyway. Intermittent torque falls in the 201-300 lb-ft range, with actual ratings dependent on application. Output shaft power is rated at 21 HP at 500 RPM and 43 HP at 1000 RPM. Compatible transmissions include Eaton/Fuller and ZF models, among others. Call us to confirm proper fit for your specific transmission.
