PROBLEM TO BE SOLVED: To improve durability and reduce the cost of a front wheel differential mechanism in a rice field working machine.SOLUTION: A front part of a machines body includes: transmissions for traveling 18, 19; a traveling transmission shaft 20 to which power from the transmissions for traveling 18, 19 is transmitted; and a front wheel differential mechanism 21 that transmits the power to right/left front wheels 1. The power of the traveling transmission shaft 20 is transmitted to the front wheel differential mechanism 21 through the first transmission mechanisms 20a, 21b. A rice field working machine includes a rear wheel transmission shaft 22 that transmits the power to right/left rear wheels 2, and transmits the power of the traveling transmission shaft 20 to the rear wheel transmission shaft 22 through the second transmission mechanisms 20b, 22a. |
