Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a structure preventing the generation of output of a hydraulic continuously variable transmission at the time of restarting of an engine, even when the engine is stopped while the hydraulic continuously variable transmission is not neutral, in a work vehicle equipped with the hydraulic continuously variable transmission.SOLUTION: A tractor is equipped with an engine; a battery; a hydraulic continuously variable transmission 120; an electric cylinder 143; and a power transmission mechanism 70. The hydraulic continuously variable transmission 120 gear-changes the output of the engine, and changes an angle of a moving swash plate to change a transmission ratio. The electric cylinder 143 is driven by being supplied power from the battery at least during the stopping of the engine. The power transmission mechanism 70 is transmitted power generated by the electric cylinder 143, and changes the angle of the moving swash plate of the hydraulic continuously variable transmission 120.SELECTED DRAWING: Figure 9
