Power supply device includes a power supply circuit with a low voltage load circuit and a high voltage load circuit connected to a plurality of batteries connected in series. A power supply circuit includes an equalizer that can prevent uneven consumption of each battery; a disconnect switch that enables the battery on the low voltage side to be electrically cut off; and a disconnect relay that enables the battery on the high voltage side to be electrically cut off. A machine controller starts an engine controller by turning on an engine key relay after turning on the disconnect relay.
