Additional Information
The Chelsea 272 Series was designed to replace and consolidate the earlier 230, 231, 236, 238, 270, and 271 Series medium-duty hot shift PTOs into a single, more capable platform. The series offers nine speed ratios and eighteen shift options, covering a broad range of transmission and application requirements.
