A work vehicle includes: an engine; a hydraulic pump that is driven by the engine; hydraulic cylinders that are extended and contracted by pressurized fluid delivered from the hydraulic pump; a work device that is moved according to the extension/contraction operations of the hydraulic cylinders; a travel device that is driven independently of the work device; an electrically driven motor that is driven by electric power generated by the engine to operate the travel device; and a controller that controls the hydraulic cylinders and the electrically driven motor. The controller controls the output power of the hydraulic pump and the output power of the electrically driven motor by changing the distribution ratios of a first torque consumed by the work device and a second torque consumed by the travel device among torques output by the engine, on the basis of a reaction force received by the vehicle body.

A tire slip control device comprises: an engine; a torque converter connected to an output shaft of the engine; a transmission for transmitting a traveling driving force from the torque converter to an axle; an engine rotation detector; an output rotation detector for the transmission; and a control for restricting the traveling driving force, wherein the control for restricting the traveling driving force judges that slip has occurred and restricts the traveling driving force when a rate of change of the ratio of an output speed of the transmission to an engine speed per unit time exceeds a first predetermined value in an initial condition in which the output speed of the transmission is a second predetermined value or smaller in a high-speed rotation area of a predetermined engine speed or larger.
