Abstract: 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.

Abstract: In a work vehicle according to the present invention, a control device calculates, for each of a plurality of speed-changing stages in a PTO transmission, an expected maximum rotational speed of PTO rotary power that is output from the PTO shaft when an engine rotational speed changing operation member is operated to a maximum extent, and shows, in a listed manner, the calculated results in a liquid crystal display part of a display device. The present invention can inform an operator of the maximum rotational speed of PTO rotary power that is output from the PTO shaft for each speed-changing stage in the PTO transmission without performing a speed changing operation on the PTO transmission.
