Abstract: A hydraulic four-wheel-drive working vehicle includes a front/rear differential-lock switch valve. The front/rear differential-lock switch valve fluidly connects forward-movement high-pressure lines of the pair of main operation fluid lines, which are fluidly connected to a main hydraulic motor, and the pair of sub operation fluid lines, which are fluidly connected to a sub hydraulic motor, and also fluidly connects the forward-movement low-pressure lines of the pair of main operation fluid lines and the pair of sub operation fluid lines. The front/rear differential-lock switch valve is capable of taking a throttling fluid-connection state of fluidly connecting the corresponding lines in a state where a throttle is interposed therebetween and a full fluid-connection state of fluidly connecting the corresponding lines in a state where the throttle is not interposed therebetween.

Abstract: There is provided an electric ground working vehicle including a left wheel and a right wheel, at least one caster, a working apparatus, an acceleration operating element for performing acceleration instructions, a turn operating element for performing turn instructions, and a control unit. The left wheel and the right wheel are independently driven by left and right electric motors respectively. The control unit controls a regenerative brake driving unit so that electric power is regenerated from the left and right electric motors to an electric power source unit when the acceleration operating element is not operated during traveling to regeneratively brake the left and right wheels. The control unit controls the brake force of the wheels so that the brake force of the wheel at the inside of a turn, among the left wheel and the right wheel, can be made greater than the brake force of the wheel at the outside of a turn when the acceleration operating element is not operated during traveling and turn instructions are inputted from the turn operating element.
