The Chelsea 221 Series Power Take-Off assembly, part number 221ZEDAX-A3XK or 221ZEDAXA3XK, is a 6-bolt, wire/cable mechanical-shift PTO built for low-speed, heavy-duty vocational work. Output shaft is a 1-1/4" round shaft with keyway. Intermittent torque rating is 250 lb-ft (339 Nm); check application pages for your specific installation. Output power runs 46-55 HP (31-40 kW), with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. The cast iron housing uses tapered cone output bearings for strong load capacity, and greaseable pump shafts reduce spline fretting and corrosion.
