Additional Information
The Chelsea 272 Series consolidates several earlier medium-duty hot shift PTO lines - the 230, 231, 236, 238, 270, and 271 series - into a single platform. The 272 Series offers nine speed ratios and eighteen shift options, giving fleet maintenance and upfit shops wide flexibility across a single part family. Rotatable flanges simplify installation in tight mounting environments. The optional Wet-Spline design extends PTO and pump shaft service life by maintaining lubrication at the spline interface. For high-torque start-up conditions, the Smart-Start option is available within the 272 Series. Markets served include aerial, construction equipment, towing and recovery, water trucks, defense, and material handling.
