Additional Information
The Chelsea 272 Series consolidates the earlier 230, 231, 236, 238, 270, and 271 Series PTOs into a single medium-duty platform. The series offers nine speed ratios, eighteen shift options, and a choice of direct-mount or driveshaft outputs. The Wet-Spline option (where configured) extends PTO and pump shaft service life. The Smart Start option is available on driveshaft output configurations to handle high-torque start-up conditions. Rotatable flanges and an integral air control valve simplify installation. Typical applications include towing and recovery, aerial work platforms, construction equipment, and water trucks.Parts Manual: Chelsea 272 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
