## Abstract

A work vehicle provided with a traveling machine body in which a battery is disposed includes a first external power supply mode and a second external power supply mode in which electric power can be supplied from the battery to the outside of the traveling machine body. In the first external power supply mode, movement of the traveling machine body is prohibited, and in the second external power supply mode, movement of the traveling machine body is permitted.

## Claims

### Claim 1

A work vehicle provided with a traveling machine body in which a battery is disposed, the work vehicle comprising:
a first external power supply mode and a second external power supply mode, wherein electric power can be supplied from the battery to the outside of the traveling machine body in each of the first external power supply mode and the second external power supply mode, and
a remote control device that operates the traveling machine body,
wherein in the first external power supply mode, movement of the traveling machine body is prohibited, and
wherein in the second external power supply mode, movement of the traveling machine body is permitted, and
wherein in the first external power supply mode, an operating of the traveling machine body by the remote control device is prohibited.

### Claim 2 (depends on 1)

The work vehicle according to claim 1, wherein movement of the traveling machine body includes traveling of the traveling machine body.

### Claim 3 (depends on 1)

The work vehicle according to claim 1, further comprising:
a work machine to be connected to the traveling machine body, wherein the traveling machine body includes:
a lifting actuator that raises and lowers the work machine, and
a drive actuator that drives the work machine,
wherein movement of the traveling machine body includes at least one of driving of the lifting actuator and driving of the drive actuator.

### Claim 4 (depends on 1)

The work vehicle according to claim 1, wherein in the first external power supply mode, electric power consumption of the traveling machine body is suppressed.

### Claim 5 (depends on 1)

The work vehicle according to claim 1, further comprising a release operation unit that performs setting on releasing of the first external power supply mode.
