The Chelsea 447XQETX-S3RB is a 447 Series Power Take-Off built on a 6-bolt mounting pattern. The 447 Series uses a one-piece input gear with a space between the two sets of gear teeth, which eliminates interference problems inside the transmission PTO aperture. Tapered bearings replace needle bearings for greater load-bearing capability. Shift options include wire/cable and mechanical. Output is via a round shaft with a 1-1/4" key. Intermittent torque for the 447 Series ranges from 201 to 300 lb-ft (301 to 400 Nm); shaft power is rated at 21 HP at 500 RPM and 43 HP at 1,000 RPM. Pro Gear and Transmission carries this genuine Chelsea unit.
