Claims (29)

1. A work vehicle comprising:

a hood comprising:

an upper surface;

an upper left surface abutted to the upper surface to form a left ridge line, wherein an edge of the upper left surface defines at least part of a left notch portion of the hood; and

an upper right surface abutted to the upper surface to form a right ridge line, wherein an edge of the upper right surface defines at least part of a right notch portion,

wherein:

the upper left surface and the upper right surface formed such that a width in the right-left direction is gradually reduced from a midway portion of the hood toward a front end of the hood;

a first end of the left ridge line and a first end of the right ridge line meet at the midway portion of a front end of the hood to form a vertex; and

the upper left surface abuts the upper right surface to form a ridge line having a first end positioned at the vertex and extending from the first end of the ridge line, in a direction toward the front end of the hood, line to a second end of the ridge line; and

head lights configured to illuminate in a forward direction, the head lights comprising:

a left head light arranged on a left side of the hood and positioned in and protrudes laterally outward from the left notch portion; and

a right head light arranged on a right side of the hood and positioned in and protrudes laterally outward from the right notch portion.

2. The work vehicle according to claim 1 , wherein a plurality of LED are disposed along the front end surfaces of the head lights.

3. The work vehicle according to claim 1 , wherein the left ridge line and the right ridge line converge at a center of a front portion of the hood in the plane view.

4. The work vehicle according to claim 1 , wherein the left ridge line and the right ridge line meet such that a first end of the left ridge line and a first end of the right ridge line are positioned at the same location on the hood.

5. The work vehicle according to claim 1 , wherein the ridge line extends continuously from the first end of the ridge line to the front end of the hood.

6. The work vehicle according to claim 1 , wherein:

a first plurality of LED are disposed along a front end surface of the left head light; and

a second plurality of LED are disposed along a front end surface of the right head light.

7. The work vehicle according to claim 1 , wherein:

the hood further comprising a left side surface and a right side surface;

the upper left surface is positioned between the upper surface and the left side surface; and

the upper right surface is positioned between the upper surface and the right side surface.
