A gearbox arrangement couples an input shaft to an output shaft whereby the output shaft is driven by the input shaft in a constant rotational direction but at two different rotational speeds depending upon the particular direction of rotation of an input shaft for a given rotational speed of the input shaft. The input shaft has an input gear integral therewith and the output shaft has an output gear integral therewith. A first unidirectional clutch couples the input shaft with the output shaft such that rotation of the input shaft in a first input direction at a first input speed rotates the output shaft in a first output direction at a first output speed, but rotation of the input shaft in a second, opposite input direction causes the first unidirectional clutch to slip. An idler gear meshes with and is driven by the input gear. An intermediate shaft has a first intermediate gear integral therewith. The first intermediate gear is meshed with and driven by the idler gear. A second intermediate gear is meshed with the output gear. A second unidirectional clutch couples the second intermediate gear with the intermediate shaft such that rotation of the input shaft in the second input direction at a second input speed rotates the output shaft in the first output direction at a second output speed, but rotation of the input shaft in the first input direction causes the second unidirectional clutch to slip. A floor maintenance machine utilizes the gearbox arrangement.
