The Chelsea 447 Series Power Take-Off Assembly, part number 447GWGPX-S5RB or 447GWGPXS5RB, is engineered around a one-piece input gear with a space between its two sets of gear teeth. That design eliminates interference problems within the PTO aperture on transmissions where adjacent gear interference is a concern. The 447 Series mounts with a 6-bolt pattern and requires no adapter plate on most applications. Shift is accomplished via air shift with a PTO/dump pump combo valve. The 447 Series delivers up to 43 HP at 1,000 RPM and up to 225 lb-ft intermittent torque (check application pages for actual torque ratings). Compatible transmissions include Eaton/Fuller, ZF, and other manufacturers. Call us to confirm proper fit for your specific transmission and application.
