Abstract
A motor control device for a working vehicle includes: a travel drive device that transmits rotation of a motor to wheels through a torque converter; a first selection device to be operated so as to select one of a power mode and an economy mode; a second selection device that is different from the first selection device; a mode switching device that switches from the economy mode to the power mode if the second selection device is operated in a state where the economy mode has been selected by the first selection device; and a speed restriction device that, when the economy mode is set, restricts a maximum rotational speed of the motor to a lower speed side than that when the power mode is set.
