Outline of the DRIVE SHAFT (PROPELLER SHAFT)
• The power from the transmission output shaft passes through center drive shaft (3), front drive shaft (1), and rear drive shaft (4), and is transmitted to the front axle and rear axle.

• When the body is articulated, or when the machine is traveling and there is shock from the ground surface, or when there is shock during operations, the position of the transmission and the front and rear axles changes. The transmission is designed so that even if the position of the components changes as a result of such shock, power can be transmitted without damage to any parts. With this design, the drive shafts have universal joints and flange bearings that enable them to handle any changes in the angle and length.
