Power Take-Off (PTO) Description and Operation: Notes
The power take-off (PTO) is an upfitter integrated system that allows the user to create an auxiliary power source. The PTO system specifically controls engine speed to values higher than normal base idle, PTO load relay engagement, and remote starting and shutdown of the engine. When the operator requests PTO, the PTO switch will be turned ON and the engine RPM will go to a default standby speed.
The PTO system is integrated with the cruise control and engine control system. The PTO system utilizes the following:
Factory Installed PTO Components
- The transmission driven PTO gear
- The in-cab PTO switch
- The power take off module (PTOM)
- The remote PTO upfitter connector
- Revised underbody structure and floor covering
