The Chelsea 447XWETX-A5XD 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, a design that eliminates interference problems inside the transmission PTO opening without requiring an adapter plate. Shift options for this series include wire/cable and mechanical. Intermittent torque for the 447 Series ranges from 201 to 300 lb-ft (305 Nm), with output power of 36 to 45 HP. Tapered bearings replace needle bearings for greater load-bearing capability. Sold by Pro Gear and Transmission.
