PROBLEM TO BE SOLVED: To provide a motor-driven tractor in which a drive source is a fuel ceil without changing a structure of a conventional engine-driven tractor extensively. SOLUTION: An electric motor 13 for traveling which drives a fuel cell 10 and a differential gear 19 by using a vehicle structure which is equipped with a rear transmission case 8 in which a clutch housing 6, a front transmission case 7 and the differential gear 19 of the engine-driven tractor are housed is arranged in the front transmission case 7. The electric motor 18 for traveling of the motor-driven tractor which uses the fuel cell 10 can be loaded inside of the transmission case 7 with maintaining the structure of the clutch housing 6 and the front transmission case 7 of the engine tractor. Furthermore, the rear transmission case 8 of the motor-driven tractor can be constituted to be completely the same one as the engine tractor, thereby, even the tractor which uses new type of a drive source, the vehicle structure having the same format as the engine tractor is possible, and common use of parts or the like is possible. As a result, it is advantageous that a manufacturing cost of the motor-driven tractor is not increased. |
