The Chelsea 447 Series Power Take-Off, part number 447KSESX-A5RK or 447KSESXA5RK, is built around a one-piece input gear with a deliberate space between its two sets of gear teeth. That design eliminates internal gear interference in the transmission PTO aperture, a problem that disqualifies conventional PTOs on certain Eaton FS series and other transmissions. Mounting is 6-bolt with no adapter plate required. Shift is air shift. The 447 Series delivers up to 43 HP at 1,000 RPM, with intermittent torque ratings in the 201-300 lb-ft range (verify actual torque on the Chelsea application pages for your specific unit). Compatible with Eaton/Fuller, ZF, and other transmission makes. Call us to confirm proper fit for your application.
