The invention is a working vehicle that has high practicality and a high degree of freedom of a turning operation. A lawn mowing vehicle includes a lawn mowing unit that includes drum wheels driven so as to rotate about an axis Axextending in a vehicle width direction as a rotational center, a frame that is connected to the lawn mowing unit, and a steering drive device that is provided in the frame. The steering drive device includes a pair of steered wheels that is disposed in the vehicle width direction, steering units that can independently steer the pair of steered wheels respectively, and wheel driving units that can rotationally drive the pair of steered wheels.

Working vehicle

In one embodiment, a circuit device that performs a certain processing operation with respect to an input signal by referring to a reference voltage and outputs the result is caused to have a function of switching the reference voltage, whereby a circuit device from which a stable output can be obtained is disclosed. The circuit device includes a comparator and a reference voltage setting circuit. The comparator compares an input voltage fed from outside with a reference voltage selected from a reference voltage set including a plurality of voltage values that are different from one another. The reference voltage setting circuit selects a voltage value lower than the reference voltage from the reference voltage set when it is detected that the input voltage in a rising transition reaches the reference voltage, selects a voltage value higher than the reference voltage from the reference voltage set when it is detected that the input voltage in a falling transition reaches the reference voltage, and sets the selected voltage value as the reference voltage of the comparator.
