TRANSMISSION MECHANISM FOR FARM TRACTOR

摘要

PURPOSE:To arrange a junction portion of a front and a rear transmission cases at a safe position in front of the center of gravity and to facilitate an assembly process by fixing a bearing supporting wall on a fixed wall inside the rear transmission case. CONSTITUTION:A bearing supporting wall 4 is made fixable on a fixed wall 110 projecting inside a rear transmission case M2, and a creep shaft 71, an auxiliary transmission shaft 72, a drive pinion shaft 61 and a front wheel driving shaft 63 is made supportable by bearings. A rear end of each shaft born by the bearing supporting wall 4 at its intermediate part is supported by a bearing part provided at a wall part 111 inside the rear transmission case M2. The bearing supporting wall 4 is fixed to the fixed wall 110 inside the rear transmission case M2. By this, a junction part of a front and the rear transmission cases can be arranged at a safe position in front of the center of gravity so as to facilitate an assembly process.
