The Chelsea 447 Series Power Take-Off Assembly, part number 447XUESX-A3RA or 447XUESXA3RA, is a 6-bolt mounted PTO engineered around a one-piece input gear with a space between two sets of gear teeth. That design eliminates interference problems within the PTO aperture on transmissions that may have adjacent gear clearance issues, so no adapter plate is required for a clean installation. Shift is accomplished via wire/cable or mechanical actuation. The output shaft is a 1-1/4" round configuration, with a keyed option available. The 447 Series is compatible with Eaton/Fuller, ZF, and other transmission manufacturers. Shaft power is rated at 21 HP at 500 RPM and 43 HP at 1,000 RPM. Intermittent torque ranges from 201 to 300 lb-ft; check the Chelsea application pages for the actual rating for your specific configuration. Genuine Chelsea from Pro Gear and Transmission.
