Abstract

A lawn mower includes a pair of left and right main frames 17 , an engine E mounted to the pair of left and right main frames 17 , a radiator for cooling water that cools the engine E, a cooling fan 11 for feeding cooling air to the radiator, and a hood 9 accommodating the engine E, the radiator and the cooling fan 11 . An air deflector plate 34 is provided between the pair of left and right main frames 17 and configured to change direction of cooling exhaust air flowing toward a ground surface.

Claims (36)

1. A lawn mower comprising:

a pair of left and right main frames;

an engine mounted to the pair of left and right main frames;

a radiator for cooling water that cools the engine;

a cooling fan for feeding cooling air to the radiator;

a hood accommodating the engine, the radiator and the cooling fan; and

an air deflector provided between the pair of left and right main frames and configured to change direction of cooling exhaust air flowing toward a ground surface,

wherein in plan view, the air deflector is provided between one of the pair of left and right main frames and a lateral side wall of the engine associated with the one of the pair of left and right main frames.

2. A lawn mower comprising:

a pair of left and right main frames;

an engine mounted to the pair of left and right main frames;

a radiator for cooling water that cools the engine;

a cooling fan for feeding cooling air to the radiator;

a hood accommodating the engine, the radiator and the cooling fan; and

an air deflector provided between the pair of left and right main frames and configured to change direction of cooling exhaust air flowing toward a ground surface,

wherein the air deflector comprises a plate-like member that extends along a plane from one to the other of the pair of left and right main frames; and

the air deflector is tilted to be disposed more downward as it approaches the other main frame.

3. The lawn mower of claim 2 , wherein at an end portion of the air deflector on the side of the other main frame, there is formed a downwardly bent portion.

4. A lawn mower comprising:

a pair of left and right main frames;

an engine mounted to the pair of left and right main frames;

a radiator for cooling water that cools the engine;

a cooling fan for feeding cooling air to the radiator;

a hood accommodating the engine, the radiator and the cooling fan; and

an air deflector provided between the pair of left and right main frames and configured to change direction of cooling exhaust air flowing toward a ground surface,

wherein the air deflector is supported in cantilever manner to one main frame of the pair of left and right main frames.

5. A lawn mower comprising:

a pair of left and right main frames;

an engine mounted to the pair of left and right main frames;

a radiator for cooling water that cools the engine;

a cooling fan for feeding cooling air to the radiator;

a hood accommodating the engine, the radiator and the cooling fan; and

an air deflector provided between the pair of left and right main frames and configured to change direction of cooling exhaust air flowing toward a ground surface,

wherein the air deflector includes a flat face portion that is tilted to be disposed more downward as it approaches from one to the other of the pair of left and right main frames and a perpendicular face portion that extends downwards from an end portion of the flat face portion on the side of the one main frame.

6. The lawn mower of claim 5 , wherein a lower end portion of the perpendicular face portion does not protrude downward beyond a lower end of the one main frame.

7. The lawn mower of claim 5 , wherein in a front/rear direction of a vehicle body, the flat face portion has a length longer than a length of the perpendicular face portion.
