Additional Information
The Chelsea 272 Series consolidates several earlier medium-duty hot shift PTO families, including the 230, 231, 236, 238, 270, and 271 series, into one platform. The series offers 9 speed ratios and 18 shift options. Common markets include aerial, construction equipment, water trucks, towing and recovery, material handling, and defense applications. Rotatable flanges allow flexible installation orientation. The Smart-Start option is designed for applications requiring high-torque engagement at start-up.
