The Chelsea 447XSETX-A5RK is a 447 Series Power Take-Off built around 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 aperture. The 6-bolt mounting eliminates the need for an adapter plate on most installations. Output is delivered through a round shaft with a 1-inch, 1/4-inch key. Shift options for this series include wire/cable and mechanical. The 447 Series carries an intermittent torque rating of 201-300 lb-ft and shaft power of 21 HP at 500 RPM or 43 HP at 1,000 RPM, with output power in the 36-45 HP range. Tapered bearings replace needle bearings for greater load-bearing capability.
