A hydraulic pump drive for use in conjunction with an engine having a drive shaft in which the pump drive is adapted to be secured to the rear end of the engine. The pump drive comprises a housing secured to the engine and having an aperture for receiving the drive shaft therethrough. A first gear is rotatably carried within the housing and is coaxially secured to the drive shaft. A second gear is also rotatably carried within the housing in a spaced and parallel relationship to the first gear and meshingly engages the first gear. The second gear is coupled to a hydraulic pump so that the drive shaft rotatably drives the hydraulic pump via the first and second gears.
