Chelsea 272 Series is the most versatile medium duty hot shift PTO on the market. It is available in hydraulic or pneumatic shift with CONTINUOUS torque capabilities up to 300 lbs ft!

The 272 Series is a reinvention of our medium duty hot shift PTOs that consolidates the 230, 231, 236, 238, 270, and271 into one series. The moving parts have been upgraded to withstand 300 lbs ft intermittently or continuously. The 272 has (9) speed ratios, (18) shift options, and the most popular direct mount and driveshaft outputs. The direct mount options include Wet-Spline technology (optional) for longer PTO and pump shaft life, while the driveshaft outputs include Smart-Start for high torque start-up conditions. The 272 is the most flexible PTO on the market and it has raised the bar on medium duty hot shift PTOs that are used in the Towing and Recovery, Aerial, Construction Equipment, and Water Truck markets.
