Additional Information
The Chelsea 272 Series was developed to replace and consolidate the earlier 230, 231, 236, 238, 270, and 271 Series PTOs into one medium-duty platform. The series includes a Smart Start option for high-torque start-up conditions and supports rotatable flanges for flexible installation. Direct-mount configurations can be ordered with the Wet-Spline option, which reduces wear on both the PTO and pump shaft over time. The 272 Series is documented in the Chelsea 272/282 Series Owner's Manual and the 272 Series Parts List (HY25-2272-M1_US).
