A gearbox parking brake has a gearing assembly in which two or more interconnected gears can rotate at different directions or speeds. A first and second planetary gear assembly and a central gear are concentrically positioned about a central rotation axis, and the central gear is rotatably engaged with the two planetary gear assemblies. An input is engaged with the central gear in order to operate the planetary gear assemblies, which may function as outputs. A gear engagement block is provided with sets of gear teeth corresponding to the planetary gear assemblies and the central gear. An actuator mechanism is operatively connected to the gear engagement block in order to displace the gear engagement block between a disengaged position and an engaged position. The gear teeth of the gear engagement block are meshed with the gearing assembly in the engaged position, restricting any movement of the gearing assembly.
