The Chelsea 447KUESX-W3RK is a 447 Series Power Take-Off built on a 6-bolt mounting pattern with a round output shaft (1-1/4" key). The 447 Series uses a one-piece input gear with a gap between its two sets of gear teeth, which eliminates interference problems inside the transmission PTO aperture, a common obstacle on a wide variety of transmissions. Shift options include wire/cable and mechanical configurations. Intermittent torque for the 447 Series ranges from 201 to 300 lb-ft (305 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. Sold by Pro Gear and Transmission.
