The PA28 Series is a constant mesh, constant drive PTO designed to suit the 10 bolt transmission openings on the MD and HD series Allison automatic transmissions. This PTO has a very high torque rating which is well suited to heavy duty applications such as transit mixers. Being driven from the input to the transmission, this PTO provides a live drive output that is available whenever the engine is running, and can be compared to an engine flywheel PTO.
