The Chelsea 447GWGPX-A5RA is a 6-bolt mounted Power Take-Off from the Chelsea 447 Series, engineered around a one-piece input gear with a space between its two sets of gear teeth. That design eliminates interference problems inside the transmission PTO aperture, making it compatible with a wide variety of transmissions without an adapter plate. Shift type is wire/cable or mechanical. Output is a round shaft with a 1-1/4" key. The 447 Series carries an intermittent torque rating of 201 to 300 lb-ft (check application pages for actual torque ratings) and delivers up to 43 HP at 1,000 RPM. Tapered bearings replace the needle bearings used in comparable PTOs, providing greater load-bearing capability. Available from Pro Gear and Transmission.
