Abstract
A work vehicle includes: a first oil supply passage causing hydraulic oil in a first hydraulic pump to be supplied to a first work device; and a second oil supply passage connected to the first oil supply passage and a mixing valve. The mixing valve is switchable between a mixing position allowing hydraulic oil in a second hydraulic pump to be supplied to the first oil supply passage through the second oil supply passage and a diverting position preventing the hydraulic oil in the second hydraulic pump from being supplied to the first oil supply passage and the second oil supply passage. The work vehicle includes a release unit configured to switch the mixing valve to the diverting position based on a load applied to the first work device.
