An engine control device is adapted to a working vehicle that is capable of switching between a power mode and an economy mode, and capable of forcibly downshifting through gears of a transmission so as to shift down to a lower speed side. The engine control device includes an engine mode determining section configured to determine whether the engine mode is in the power mode or the economy mode, a gear detection section configured to detect current gear of a plurality of gears, a kick-down detection section configured to detect a kick-down instruction, and a control section configured to switch the engine into the power mode when the kick-down instruction is detected while the engine mode is in the economy mode and the gears are in the lowest gear.
