The Chelsea 447 Series Power Take-Off Assembly, part number 447KSESX-A3XQ or 447KSESXA3XQ, is a 6-bolt mounted PTO engineered around a one-piece input gear with a deliberate space between its two gear-tooth sets. That design eliminates internal interference within the PTO aperture on transmissions where adjacent gear clearance is tight. Compatible with Eaton/Fuller, ZF, and other transmission manufacturers, it uses wire/cable mechanical shift and accepts a 1-1/4" round output shaft with keyway. Output power runs 21 HP at 500 RPM and 43 HP at 1000 RPM. Intermittent torque is rated 201-300 lb-ft; verify your exact figure on the Chelsea application pages.
