The Chelsea 447XUITX-W3XK is a 447 Series Power Take-Off built on a 6-bolt mounting configuration 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 gear tooth sets, a design that eliminates interference problems inside the transmission PTO opening without requiring an adapter plate. Tapered bearings replace needle bearings for greater load-bearing capability. Shift options for this series include wire/cable and mechanical actuation. Intermittent torque for the 447 Series ranges from 201 to 300 lb-ft, with output power reaching 36 to 45 HP depending on application. The 447XUITX-W3XK is sold by Pro Gear and Transmission.
