The Chelsea 447 Series Power Take-Off, part number 447KWESX-A3XK or 447KWESXA3XK, is built around a one-piece input gear with a gap between its two sets of gear teeth, a design that prevents interference inside the PTO aperture on transmissions where adjacent gear contact is a concern. The 447 Series mounts via a 6-bolt pattern and ships with shift options including wire/cable and mechanical. Output goes through a 1-1/4" round shaft with keyway. Intermittent torque ratings for this series fall in the 201-300 lb-ft range (verify actual rating on the Chelsea application pages for your specific transmission). Compatible transmissions include Eaton/Fuller and ZF models, among others. Call us to confirm proper fit for your application.
