Abstract

PURPOSE:To make the environment of an air cleaner desirable and attain the low center-of-gravity of a body and the reduced height of a rear part bonnet so as to easily obtain the large capacity of a grass collecting container by the disposition of an engine through the effective use of spare space below a driver's seat and the rational disposition structure of a motive power part due to auxiliary machinery such as an air cleaner being disposed in the height suppressed state. CONSTITUTION:An engine E is disposed below a driver's seat 19 provided at the body front part in a front mounted lawn mower, in a position between front and rear axles 3a, 4a. A radiator positioned right behind the engine E, and a fuel tank 8 positioned behind the radiator are equipped in bonnet 2 provided at the body rear part. An air cleaner 17 is disposed at a left side place above the radiator in the bonnet 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reasonably arranged prime mover in a front mount lawnmower.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Laid-Open No. 2-80026, a driver's seat is arranged at a position above a front axle, and a body equipped with an engine hood is installed behind the driver's seat. There is known a front mount lawn mower that is configured as a wheel steering type and has a grass container above the engine bonnet.

[0003]

In the above-mentioned prior art, the fact that the driving part is housed in the bonnet at the rear of the machine body has the advantage that engine noise over the operating part can be kept relatively low, but the bonnet is bulky. Then, the position of the grass container attached on top of it also becomes high, and the center of gravity becomes high, or there is a demerit that the volume of the grass container cannot be increased so much, and there was room for improvement. An object of the present invention is to reduce the center of gravity of the airframe so that the grass container can have a large capacity.

[0004]

In order to achieve the above object, the present invention provides a front mount lawn mower with an engine disposed below the driver's seat at the front of the machine body and at a position between the front and rear axles. A radiator located immediately after the engine and a fuel tank located on the rear side of the radiator are installed in the bonnet at the rear of the fuselage, and an air cleaner is installed in the bonnet at a lateral position above the radiator. It is characterized by

[0005]

In the prior art described above, paying attention to the fact that there is relatively room in the space below the driver seat, the engine is
The position is changed to the lower abdomen of the aircraft. According to this, since the heavy engine can be arranged between the front and rear axles at a position below the driver's seat, that is, in the lower abdomen of the body, the center of gravity of the body can be lowered and a radiator should be mounted immediately after the engine. As a result, the height at which the radiator, which is located in the front portion inside the bonnet, can be reduced, and the upward protruding height in the bonnet can be reduced. In addition, it is easy to set the fuel tank to a shape that suppresses its height, such as a flat shape that is wide in the lateral direction, and an air cleaner that tends to be a relatively bulky three-dimensional shape is installed on the side of the radiator. By arranging them in places, the height of the hood that covers these radiator, fuel tank, and air cleaner can be made lower than before, and the air cleaner is located near the engine, which is convenient for reducing intake resistance. It is possible to place it at a relatively high position where it is difficult for dust to rise as the vehicle travels and it is difficult for dust to rise.

[0006]

Therefore, the engine can be arranged below the driver's seat, and the ratio of the prime mover to the engine can be reduced by the auxiliary parts such as the air cleaner. It was possible to provide a front-mounted lawn mower that can lower the center of gravity of the airframe and reduce the height of the bonnet at the rear of the airframe, and can easily increase the capacity of the grass container.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 4, the mower M that can be raised and lowered is provided in front of the machine body, and the control unit 1 including the driver's seat 19 at the front of the machine body is
An engine bonnet 2 is provided at each of the rear portions, an engine E is disposed at the lower abdomen of the machine body, and drive front wheels 3 and steering rear wheels 4 are provided to constitute a riding type lawnmower capable of traveling. The left and right front wheels 3 are pivotally supported by a mission case 5 fixed to the front end of the machine frame F, and the pair of left and right rear wheels 4 are steered around the vertical axis P at the rear part of the machine frame F. Installed. The body frame F is composed of a pair of left and right main frames 6 and 6 and a lower frame 7 suspended from the main frame 6, and the engine E is mounted on the lower frame 7 in a state of being positioned between the front and rear axles 3a and 4a. I am doing it. As shown in FIG. 3, the engine bonnet 2 can swing and open / close about a horizontal axis X provided at a rear portion thereof. When the grass collection container 9 is mounted, as shown by a solid line in FIG. The posture can be freely changed and maintained between the open posture in the inclined state along the bottom surface and the closed posture shown by the phantom line. A fuel tank 8 is mounted at a position closer to the rear in the engine bonnet 2, and a grass container 9 is detachably mounted at a position directly above the bonnet so that dumping can be performed around the left and right axis Y of the rear portion. It is located at. As shown in FIGS. 1 to 3, a rear blow-off type cooling fan 10 and a radiator 12 are arranged in this order from the front behind the engine E, and an intake grill 11 provided on the front surface of the engine bonnet 2 and The cooling exhaust air after cooling the radiator 12 by the outside air sucked from the side of the engine E is discharged toward the rear of the machine body. The pipe connecting portion 13 above the radiator 12 is mounted rearward, the pipe 14 connecting to the engine E is routed so as to bypass the right side portion of the radiator 12, and the air cleaner 17 is provided on the left shoulder opening portion of the radiator 12. It is located at. Further, a dustproof net 18 that can be pulled out upward is arranged on the front surface of the radiator 12, and a partition wall 20 is further provided between the radiator 12 and the fuel tank 8.

The grass container 9 can be installed via a four-legged support member 15 bolted to the machine body, and as shown in FIG. 5, the side surface of the portion to which the duct 16 is connected is slightly inward. And is formed in a substantially trapezoidal shape that straddles the engine bonnet 2 left and right.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
