A mobile work platform includes an operator platform (6), a base (2) and a lift mechanism (4) for lifting the operator platform relative to the base. A hydraulic drive system for the mobile work platform includes an internal combustion engine (14), an electric motor (24) and a hydraulic pump (26). The internal combustion engine (14) and the electric motor (24) are constructed and arranged so as to be capable of driving the hydraulic pump (26) either separately or together.
