Claims5
An electric work vehicle, comprising:
- a work device;
- a battery;
- a motor drivable on electric power supplied by the battery;
- a travel device drivable by the motor;
- a hydraulic pump drivable by the motor to supply operating fluid to an operating mechanism of the work device;
- a transmission positioned backward of the motor to transmit a driving force of the motor to the travel device;
- a first rotor;
- and
- a second rotor;
- wherein
- the hydraulic pump is next to the motor;
- the transmission includes a transmission input shaft as an input shaft;
