PROBLEM TO BE SOLVED: To provide a drive control mechanism for a work vehicle which, when it is desired to improve the driving force of a work vehicle relative to a ground contact area, allows the driving force to be improved quickly.SOLUTION: A drive control mechanism for a work vehicle includes a four-wheel drive electromagnetic valve 34 that switches between a four-wheel drive state for transmitting driving force to front wheels 2,2 and rear wheels 3,3 of a tractor 1 and a two-wheel drive state for transmitting driving force to only the rear wheels 3,3, state detection means that detects a state in which it is desired to improve the driving force (traction) of the tractor 1 relative to a ground contact area, and a vehicle ECU 44. If it is desired to improve the driving force, the ECU 44 automatically switches the tractor 1 to the four-wheel drive state. |
