Abstract:
A work vehicle includes an engine mounted on a traveling body, a straight-traveling system transmission path including a first stepless transmission device, and a turning system transmission path including a second stepless transmission device, the work vehicle being configured to combine outputs of the straight-traveling system transmission path and an output of the turning system transmission paths to drive left and right traveling units. The work vehicle also includes control sections that control the outputs of the straight-traveling system transmission path and the output of the turning system transmission paths in cooperation with each other, a transmission operation tool that specifies the output of the straight-traveling system transmission path, and a detector that detects the output of the straight-traveling system transmission path. The control sections select one of an instruction value from the transmission operation tool and an actually measured value from the detector and set the output of the turning system transmission path.
