Abstract

In a work vehicle, a cutoff-pressure-setting part sets cutoff pressure at a predetermined first pressure value when vehicle speed is greater than a predetermined first speed threshold, and at a second pressure value greater than the first pressure value when vehicle speed is equal to or less than a second speed threshold less than the first speed threshold. When the vehicle is moving forward and the forward/backward switch lever is in forward motion position, or when the vehicle is moving backward and the forward/backward switch lever is in backward motion position, the second speed threshold is set to a predetermined first value. When the vehicle is moving forward and the forward/backward switch lever is in backward motion position or when the vehicle is moving backward and the forward/backward switch lever is in forward motion position, the second speed threshold is set to a second value lower than the first value.
