Abstract
A work vehicle equipped with: a straight-traveling system transmission path including a first stepless transmission device, a turning system transmission path including a second stepless transmission device, left and right traveling units that receive a driving force from an engine and move the work vehicle in forward and in reverse, and a brake operation tool that actuates a brake mechanism. The output of the straight-traveling system transmission path and the output of the turning system transmission path are combined to drive the traveling units. When the operation amount to the brake operation tool exceeds a first predetermined amount, a control section blocks the driving force output from the first stepless transmission device, and at the same time, sets a swash plate of the second stepless transmission device in a neutral state.
