Abstract:
To provide a work vehicle capable of stable traveling with good fuel consumption by appropriate output changes being made while linear traveling and while turning traveling.SOLUTION: A travel vehicle body 1 includes a position information acquisition device 140 acquiring position coordinates; a speed gear 30 changing travel output of the travel vehicle body 1; a steering member 6 performing steering operation of the travel vehicle body 1; an automatic straight advancing device 401 which operates the steering member 6 to advance a machine body straightforward; a controller 200; and an operation member 402 acquiring a start reference point A and a termination reference point B while the machine body travels straightforward. The speed gear 30 has a variable capacity motor 30a, can control an increase/a decrease of a capacity of the variable capacity motor 30a with the controller 200. When the operation member 402 is operated and the starting reference point A during straight advancing is acquired, the controller 200 lowers the capacity of the variable capacity motor 30a; when the start reference point B of the straight advancing is acquired, the controller increases the capacity of the variable capacity motor 30a.SELECTED DRAWING: Figure 37
