The Chelsea 447 Series Power Take-Off, part number 447XSETX-A3RK or 447XSETXA3RK, is a 6-bolt mounted PTO engineered around a one-piece input gear with a deliberate space between its two sets of gear teeth. That gap eliminates internal interference problems inside the transmission PTO aperture, a common fitment challenge on Eaton/Fuller, ZF, and other transmission brands this unit is rated for. Shift is accomplished via wire/cable mechanical actuation. The output shaft is a 1-1/4" round with keyway. Output power reaches 43 HP at 1,000 RPM, with intermittent torque rated at 201-300 lb-ft (check application pages for actual torque ratings). Tapered bearings replace the needle-bearing design found in comparable units, providing greater load-bearing capability. Call us to confirm proper fit for your application.
