A power take-off (PTO) system for a motor vehicle includes a PTO housing. The PTO housing is mounted to a transmission case. A disconnect clutch assembly is positioned within the PTO housing acting when supplied with a first volume of a pressurized oil from the transmission case to engage an output shaft member. A controlled lube oil circuit is isolated from the first volume of the pressurized oil. The controlled lube oil circuit supplies a second volume of the pressurized oil directly to the disconnect clutch assembly to lubricate the disconnect clutch assembly. A lube oil drain return is connected to the PTO housing. The lube oil drain return receives oil that collects inside the PTO housing to be returned to the transmission case.

A method and apparatus for delivering power to a hybrid vehicle is disclosed. The apparatus includes an apparatus for delivering power to a hybrid vehicle, the hybrid vehicle including a powertrain having a power take-off coupling, the powertrain including an engine and a transmission. The apparatus includes an electric motor operable to generate a torque, the motor being coupled to transmit a starting torque through the power take-off of the powertrain for starting the engine.

A work vehicle includes two types of PTO shafts, a PTO drive unit, a storage unit, a PTO gear shift operation unit, a PTO shaft detection sensor, a PTO gear shift sensor and a control device. The storage unit stores a PTO shaft, which is not connected to the driven portion, of the two types of PTO shafts. The PTO gear shift operation unit performs gear-shifting of the gear shift mechanism. The PTO shaft detection sensor detects a type of the PTO shaft stored in the storage unit. The PTO gear shift sensor detects an operation state of the PTO gear shift operation unit. The control device decides a propriety of a combination of a detection value of the PTO shaft detection sensor and a detection value of the PTO gear shift sensor.
