Description
The Chelsea 447 Series Power Take-Off Assembly, part number 447XSETX-A3AF or 447XSETXA3AF, is a 6-bolt mount PTO engineered around a one-piece input gear with a space between its two sets of gear teeth. That design eliminates interference inside the PTO aperture on transmissions where adjacent gear contact is a concern. Compatible with Eaton/Fuller, ZF, and other transmission manufacturers, it accepts wire/cable or mechanical shift and delivers output power in the 36-45 HP (31-40 kW) range at the shaft. The 1-1/4″ round output shaft is also available with a key. Intermittent torque ratings for the 447 Series run 201-300 lb-ft (301-400 Nm); consult the application pages for the actual rating for your specific configuration. Call us to confirm proper fit for your application.
