Abstract
A travel control unit of a working vehicle includes an HST which is a hydraulic continuously variable transmission having a hydraulic pump and a hydraulic motor, a pedal sensor which is an operator sensor which detects a position of an acceleration pedal which is an acceleration operator, and a controller which changes a displacement of the hydraulic pump based on the position of the acceleration pedal. The controller increases the displacement of the hydraulic motor as the displacement of the hydraulic pump is reduced due to a displacement of the acceleration pedal to a low-velocity side.
