The Chelsea 280 Series power take-off device combines the 277 and 278 Series models into a single PTO model.

The 280 Series features a single continuous-duty torque rating with no intermittent rating. Pump clearance issues have been improved with rotatable cast iron flanges and the Wet Spline Pump Flange option that provides 7 to 10 times greater shaft life.

Broader coverage of speed ranges expands from five ratios to nine ratios and includes lower and higher speeds. The standard output shaft features a positive stop for Driveline outputs that eliminates the ability for shaft couplings to damage oil seals.

Three option positions for the integrated solenoid valve. A remote-mounted option provides maximum clearance under the truck. The new 280 Series includes a pressure/lube hose.
