Abstract

A work vehicle includes an engine, an authentication processing unit for permitting the engine to be started only when stored authentication information and authentication information inputted by a manual operation are identical to each other, storage means for pre-storing the stored authentication information, a first switch and a second switch for performing the manual operation, authentication information identifying means for comparing the inputted authentication information acquired by the authentication processing unit with the stored authentication information, and power controlling means for allowing power to be supplied to a starter motor of the engine when the inputted authentication information is identical to the stored authentication information at the authentication information identifying means. The authentication processing unit is configured to acquire, as the inputted authentication information, the number of operation iterations of the first switch and the number of operation iterations of the second switch.

Claims

1. A work vehicle, comprising:

an engine;

an authentication processing unit for permitting the engine to be started only when stored authentication information and authentication information inputted by a manual operation are identical to each other;

storage means for pre-storing the stored authentication information;

a first switch and a second switch for performing the manual operation,

wherein the stored authentication information is the number of operation iterations of the first switch and the number of operation iterations of the second switch, at least one of the number of operation iterations of the first switch and the number of operation iterations of the second switch being set to at least two, and the authentication processing unit being configured to acquire, as the inputted authentication information, the number of operation iterations of the first switch and the number of operation iterations of the second switch;

authentication information identifying means for comparing the inputted authentication information acquired by the authentication processing unit with the stored authentication information; and

power controlling means for allowing power to be supplied to a starter motor of the engine when the inputted authentication information is identical to the stored authentication information at the authentication information identifying means.

2. The work vehicle according to claim 1, further comprising:

operation iteration number displaying means for displaying, on a display, the number of operation iterations of the first switch and the number of operation iterations of the second switch.

3. The work vehicle according to claim 1, wherein

the first switch and the second switch are configured to be operable by a single operational tool.

4. The work vehicle according to claim 1, further comprising:

authentication restricting means for not allowing the authentication processing unit to provide authentication when the authentication information cross-checking means determines, for a set number of times of consecutive iterations, that the inputted authentication information is not in conformity with the stored authentication information, until a set period of time elapses thereafter.
