Abstract
With regard to a tractor having a high-powered engine, universal joints must be enlarged, whereby the attachment work of a power transmission shaft becomes difficult. Furthermore, the kind of the universal joints to be used is limited, thereby being inconvenient. Therefore, a tractor is constructed so that a transmission casing is arranged in a rear portion of a vehicle body, a front axle casing is arranged in the front portion of the vehicle body, and power from an engine is transmitted from an output shaft supported by the transmission casing through a power transmission shaft to an input shaft supported by the front axle casing. The tractor is characterized in that a gear casing is disposed between the transmission casing and the front axle casing, the output shaft of the transmission casing and an input shaft of the gear casing are arranged on a same line and connected to each other, and the input shaft of the front axle casing and an output shaft of the gear casing are arranged on a same line and connected to each other.
