The Chelsea 880 Series Power Take-Off, part number 880XBAKX-V3XS or 880XBAKXV3XS, is an 8-bolt, lever mechanical shift PTO rated for up to 500 lb-ft intermittent torque. The output shaft is a 1-1/2″-10T spline with a 1410 companion flange, and shaft power reaches 48 HP at 500 RPM and 95 HP at 1000 RPM.
