Abstract
A bearing support frame (10) is disposed within a rear end portion of a tractor front housing (1) having an open rear end. The frame is secured to internal boss (2c) on a transmission casing (1), which is fastened to the rear of the front housing and has an open front end, and is used for supporting respective one ends of transmission shafts (4, 5, 7, 8) for both of an additional speed change mechanism (6), which is disposed within a rear half of the front housing, and a main speed change mechanism (9) which is disposed within a front half of the transmission casing. An intermediate shaft (17) interposed between the additional and main change mechanisms is also supported by the support frame. The support frame which is preferably composed of front and rear bearing support plates (10A, 10B) facilitates an easy assembly of the change mechanisms.
