Abstract

PURPOSE:To widen the front field of vision of the operator and increase the angle of turn of front wheels at steering, by placing a radiator behind an engine and by gradually reducing forwards the width of a hood covering the radiator and the engine. CONSTITUTION:A radiator 9 is placed behind an engine 8. The width of the engine 8 is made smaller than that of the radiator 9. The side walls 11a of a hood 11 covering the radiator 9 and the engine 8 extend forwards alongside the radiator 9 and the engine 8 located in front of it, so that the width of the hood is gradually reduced forwards. The side walls 11a of the hood 11 have cooling air inlet openings 12 near a dashboard 13. The front wall of the hood 11 has cooling air outlet openings 14.

Generally, in a tractor, an engine is disposed in front of a driver's seat, and a radiator is disposed in front of the engine. The widths of the engine and the radiator are almost the same, so the hood that covers the engine and the radiator is also box-shaped with straight sidewalls along the sidewalls of the engine and the radiator. is normal. However, as described above, since such a bonnet is placed in front of the driver's seat, it obstructs the operator's forward view, so it is desirable to make it as small as possible.

The present invention has been made in view of the above points, and has a configuration in which, in a tractor in which an engine is mounted in front of the driver's seat, a radiator is arranged at the rear side of the engine, and the width of the engine in the left-right direction is equal to that of the radiator. It is characterized by having a narrower width than the radiator and the width of the bonnet that covers the radiator and the engine in the left-right direction is tapered. With this configuration, the forward visibility of the operator is improved, and Even when the steering wheel is fully extended to the left or right, the front wheels do not interfere with the bonnet, and therefore, the turning angle of the front wheels can be increased to create a tractor with a small turning radius. This is a tractor with many advantages.

The present invention has the above configuration, and generally, even if the engine is made smaller, as long as the horsepower remains the same, the radiator cannot be made smaller due to the cooling capacity.
With the conventional radiator placed in front of the engine, it was not possible to make the bonnet smaller, but according to the present invention, the radiator is placed at the rear of the engine, and the width of the engine is made smaller than the radiator. The width of the bonnet is small, and the width of the bonnet is tapered toward the front, providing good forward visibility from the driver's seat at the rear. The turning angle of the front wheels (2) when the handlebar (5) is turned all the way to the left and right can be increased, and a tractor with a small turning radius and therefore good workability can be obtained, and furthermore, Since the radiator is located at the rear side, the cooling air from the radiator can be taken in from the rear side and sent out to the front.Therefore, the hot air coming out of the bonnet is not sent out to the operator side. This has the effect of improving livability. Furthermore, since the bonnet of the present invention has a tapered shape, it is possible to obtain a tractor with a good external appearance that has a sharp cut toward the front.
