Реферат: A hydraulically operated shifter for use in a power take-off includes a shifter housing having an interior, a fluid port, and an opening. A shifter piston is disposed within the interior of the shifter housing and is movable in first and second directions. The shifter piston defines first and second chambers within the interior of the shifter housing. The fluid port communicates with the first chamber, and the opening communicates with the second chamber. The shifter piston includes a passageway that provides communication between the first and second chamber defined within the interior of the shifter housing. A shift actuator is supported on the shifter piston for movement therewith and extends through the opening provided in the shifter housing.
