The Chelsea 447XUETX-A5RK is a 447 Series Power Take-Off built on a 6-bolt mounting pattern with a round shaft output (1-inch, 1/4-inch key). The 447 Series uses a one-piece input gear with a space between its two sets of gear teeth, designed to eliminate interference problems inside the transmission PTO opening without requiring an adapter plate. Shift options include wire/cable and mechanical. The series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 43 HP at 1,000 RPM at the output shaft. Tapered bearings replace needle bearings for greater load capacity. Available from Pro Gear and Transmission.
