Such problems as deterioration of work efficiency due to tire slip, lowering of durability due to damage of a tire, and increase in burden of tire exchange expense on the user are solved by preventing repetitive occurrence of tire slip under a situation with the risk of occurrence of tire slip, e.g. during excavation work. The working vehicleof the present invention includes a working machine by which engine power is transmitted as driving force to a tire through a transmission passage. In the driving force transmission passage of the working vehicle, a driving device varying means for varying the driving force transmitted to the tire freely is provided. A tire slip detection means detects the occurrence of tire slip. When tire slip is detected by the tire slip detection means, a driving force measuring means measures the driving force at the time when tire slip is detected. A driving force control means controls the driving force varying means such that the driving force becomes lower than that at the time when tire slip is detected. |
