Electric work vehicle
An electric work vehicle includes a rear housing, a first motor to drive a first rear wheel, the first motor being supported by the rear housing, and a second motor to drive to a second rear wheel, the second motor being supported by the rear housing. The first motor is connected to a first gearing to drive the first rear wheel. The second motor is connected to a second gearing to drive to the second rear wheel. An outermost portion of the first gearing is located inside of the first motor in a left-right direction of the vehicle. An outermost portion of the second gearing is located inside of the second motor in the left-right direction of the vehicle.
