A gearbox is mounted at one of the stations having its output shaft in communication with the impeller and scraper. The gearbox is mounted detachably so that it can be repositioned between any one of the plurality of mounting stations by rotating the gear box about the output shaft. The gear box is generally comprised of a casing having first and second casing halves detachably mounted to each other and defining an enclosed chamber. Rotatably mounted in the casing is an input shaft carrying an enclosed gear. The output shaft is rotatably mounted in the casing, carrying an enclosed second gear. The gear box further contains a plurality of colinearly aligned bores for the mounting of a countershaft and associated gear for providing a means of communicating the first gear with the second gear.
