Additional Information
The Chelsea 272 Series was developed to replace and consolidate the earlier 230, 231, 236, 238, 270, and 271 PTO lines into a single, more versatile medium-duty platform. The 272 Series offers nine speed ratios and eighteen shift options, giving it broad compatibility across vehicle and application types.
