The Chelsea 447 Series Power Take-Off Assembly, part number 447XWESX-A3AF or 447XWESXA3AF, is a 6-bolt mounted PTO engineered around a one-piece input gear with a space between its two sets of gear teeth. That design eliminates interference problems inside the transmission PTO aperture, making the 447 Series a practical choice where adjacent gear clearance is tight. Shift is air shift. The output is an SAE B 2 or 4-bolt flange with a 1" 15-tooth SAE BB shaft. Intermittent torque falls in the 201-300 lb-ft range; check application pages for the exact torque rating of this configuration. Output power is rated at 36-45 HP, with shaft power of 21 HP at 500 RPM and 43 HP at 1000 RPM. Compatible transmissions include Eaton/Fuller and ZF units, among others. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
