A power take-off includes a housing that is adapted to be supported on a source of rotational energy, an input mechanism that is supported within the housing and adapted to be rotatably driven by the source of rotational energy, and an output mechanism that is supported within the housing and rotatably driven by the input mechanism. At least one of the input mechanism and the output mechanism includes a pair of mating gears. An eddy current damper is supported within the housing and configured to exert a drag torque on either or both of the mating gears during operation of the power take-off. The eddy current damper may provide a variable amount of such drag torque, a constant amount of such drag torque, or a combination of both.

An integrated electric power take-off includes an electric motor that is driven by an electric motor of an electric vehicle, a hydraulic pump or a similar device that is adapted to operate a rotatably driven accessory provided on the electric vehicle, and a geartrain system connected between the electric motor and the hydraulic pump. The geartrain system is an integral portion of the integrated electric power take-off that permits an optimal selection of the electric motor and the hydraulic pump to be made for each specific application.

A shift lock-out device is used with a gearbox containing one or more gears and a clutch mechanism that is operable to selectively engage the one or more gears to provide first and second gear ratios. The shift lock-out device includes a housing having an inlet port that communicates with a source of pressurized fluid and an outlet port that communicates with the clutch mechanism. A valve element is supported within the housing for movement between an opened position, wherein fluid communication is permitted from the inlet port to the outlet port, and a closed position, wherein fluid communication is prevented from the inlet port and an outlet port. A pilot control valve selectively permits and prevents the application of pressurized fluid from a pilot fluid source against the valve element to selectively move the valve element between the opened and closed positions.
