PTO Requirements Flowchart

Notice

The ZF-FreedomLine transmission is delivered pre-programmed to accept both a stationary PTO (for use in

neutral) and a non-stationary PTO (for use in the default PTO gear only). The installation of the PTO is the

responsibility of the owner. An improperly installed PTO may damage the transmission gearing, requiring

a transmission replacement.

The Transmission Controller Unit (TCU) actively monitors the PTO and acts accordingly. Pin A of the PTO

connector must be wired into the PTO switch. Pin C of the PTO connector must be wired into the series of

relays that activate the PTO. Pin B of the PTO connector must be wired into the ball switch that

acknowledges the engagement of the PTO.
