Tractor
A tractor in which a basic shape of a hot-wind blocking plate disposed between a motor unit and an operation unit is commonalized as a sharable element, and cutting of an outer edge portion of the hot-wind blocking plate enables application to various specifications including different sizes of motors and operation units, thus achieving convenience in assembling the tractor, enabling mass production by using the sharable element, enabling an efficient inventory storage, and providing an advantage in costs. The tractor includes: a hot-wind blocking plate disposed between a motor unit and an operation unit, the dimension of the hot-wind blocking plate being adjustable by cutting an outer edge portion of the blocking plate; and an operation unit component mounted in the outer edge portion of the hot-wind blocking plate, a position where the operation unit component is mounted is changeable depending on a specification of the operation unit.

8. The apparatus of claim 7 , wherein:
the first and second angle are non-orthogonal to the centerline;
the first axis and the second axis intersect;
the first set of openings are spaced at equal intervals with respect to a left-right direction that is substantially orthogonal to the centerline; and
the second set of openings are spaced at equal intervals with respect to the left-right direction.
9. The apparatus of claim 6 , wherein:
the heat cover defines:
a first end that defines one or more flanges configured to couple the heat cover to a wind blocking plate disposed between the hood and the dashboard;
a second end;
an upper surface that extends between the first end and the second end and defines an inverted U shape; and
a lower surface that opposes the upper surface; and
the plurality of openings extend between the upper surface and the lower surface.
10. The apparatus of claim 9 , wherein:
each opening of the first set of openings includes a first portion that is closer to the first end than is a second portion of the opening; and
the first portion is closer to the centerline than is the second portion.
11. The apparatus of claim 9 , wherein the upper surface defines:
a plurality of guide pieces protrude over at least portion of a respective heat opening of the plurality of openings;
a first edge portion that defines a first recess at the first end of the heat cover; and
a second edge portion that defines a recess at the second end of the heat cover.
12. The apparatus of claim 11 , wherein:
the plurality of guide pieces are positioned such that heat discharged from the first set of openings is directed toward a left side of the hood and heat discharged from the second set of openings is directed toward a right side of the hood; and
the work vehicle includes a tractor.
13. The apparatus of claim 5 , wherein the work vehicle includes a tractor.
14. A tractor comprising:
a blocking plate disposed between a motor unit and an operation unit of a tractor;
a dashboard coupled to a first side of the blocking plate;
a hood configured to cover the motor unit; and
a heat cover coupled to a second side of the blocking plate, the heat cover positioned between the blocking plate and the hood, the heat cover defining:
a plurality of openings that include:
a first set of openings extending along a first axis that is angularly disposed relative to a centerline of the hood; and
a second set of openings extending along a second axis that is angularly disposed relative to the centerline of the hood.
15. The tractor of claim 14 , wherein each opening of the plurality of openings include:
a first end; and
a second end that is opposite the first end, the second end positioned further from the centerline of the hood than is the first end.
