The Chelsea 447KWESX-A3XJ is a 447 Series Power Take-Off (PTO) built on a 6-bolt mounting pattern. The 447 Series uses a one-piece input gear with a gap between its two sets of teeth, designed to eliminate interference problems inside the transmission aperture, a known challenge on a wide range of transmissions. Shift options for this series include wire/cable and mechanical. Output is through a round shaft with a 1-1/4" key. The series intermittent torque rating runs 201 to 300 lb-ft (301 to 400 Nm), with shaft power of 21 HP at 500 RPM and 43 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load capacity. Available from Pro Gear and Transmission.
