Abstract
To provide a working vehicle that includes a first transmission mechanism for transmitting power of a first motor to a working power output part, a second transmission mechanism for transmitting power of a second motor to a travel power output part, a first inverter connected to the first motor, and a second inverter connected to the second motor, which can prolong a time allowing work to be continuous with a simple structure.SOLUTION: A working vehicle includes a cooling device 60 for circulating and supplying a coolant to a first motor 21, a second motor 22, a first inverter 23, and a second inverter 24. The cooling device 60 circulates and supplies the coolant in order through the first inverter 23 and the second inverter 24 to the first motor 21 and the second motor 22.SELECTED DRAWING: Figure 5
