Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mower equipped with a hammer knife type cutting blade device in front of a machine body and suitable for cutting grass on the upper surface of a ridge.

[0002]

2. Description of the Related Art A mower having a hammer knife type cutting blade device in which a large number of flares are pivotally supported on a laterally extending spindle is known from U.S. Pat. No. 3,433,003.

[0003]

When such a hammer knife type cutting blade device is installed in front of a machine body having left and right wheels and the grass on the upper surface of the ridge is to be mowed, a hammer knife in front of the machine body is provided. Since the weight of the type of cutting blade device occupies a considerable weight of the entire mower, when the wheels run near the left and right sides of the upper surface of the ridge, the mower easily slips off the ridge.

Therefore, an object of the present invention is to allow the wheels on the left and right sides of the machine body to run near the center of the upper surface of the ridge while cutting the grass on the edge side of the upper surface of the ridge by the hammer knife type cutting blade device in front of it. It is to provide a mower capable of preventing slipping from a ridge.

[0005]

In order to solve the above problems, the present invention is directed to a hammer knife type in which a large number of flares are pivotally supported by a support shaft extending in the lateral direction in front of a machine body having left and right wheels. A grass mower provided with a cutting blade device, characterized in that the cutting blade device is configured to overhang one side of the machine body.

[0006]

Operation: With the wheels on the left and right of the machine running near the center of the ridge, the grass on the edge side of the ridge can be cut by the hammer knife type cutting blade device that overhangs to one side of the machine in front of the wheels. ..

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 showing a schematic appearance of a mower to which the present invention is applied, 1 is a body, 3 is a wheel, 5 is a handle,
Reference numeral 7 is an engine, 9 is a power transmission device, and 11 is a cutting blade device. The machine body 1 includes wheels 3 and 3 on both left and right sides, a pair of left and right handles 5 and 5 standing upright, and an engine 7.

In the embodiment, the engine 7 is provided on the right side of the machine body 1.
A power transmission device 9 is provided by means of a belt pulley device, and power is transmitted to a hammer knife type cutting blade device 11 provided in front of the machine body 1 together with the left and right wheels 3 and 3. That is, the cutting blade device 11 is formed by connecting the rear part of the cutter housing 13 to the front part of the machine body 1, and inside the cutter housing 13, a rotary shaft 15 extending in the lateral direction is supported as shown in FIG. The power transmission device 9 is connected to the rotary shaft 15.

Disc rotors 17 are coupled to the left and right ends and the central portion of the rotary shaft 15, and a plurality of (for example, three) support shafts parallel to the rotary shaft 15 through the disc rotors 17 ... 19 ... is erected. A plurality of (for example, three or four or more) bifurcated flares 21 ... Which function as hammer knives are swingably supported on the support shaft 19, and a flare stopper shaft is provided between the support shafts 19. 23 are arranged.

Further, the cutter housing 13 is provided with a steered wheel support frame 25 extending forward, and the steered wheel support arm 2 is provided at the front end of the frame 25 via a vertical shaft 27.
The steering wheel 31 is supported by the arm 29. A steering arm 33 is provided on the vertical shaft 27, and a tie rod 35 connected to the arm 33 and extending rearward is connected to a projecting rod 39 provided on a steering operation lever 37 provided near one of the handles 5. Has been done.

As described above, in the grass mower provided with the hammer knife type cutting blade device 11 in front of the machine body 1, the cutter housing 13 accommodating the flares 21 is overhung to the left side of the machine body 1 in the embodiment. It is configured. That is, as shown in FIG. 2, the wheels 3 on the left side of the machine body 1
The left side is further overhanged by a predetermined amount.

Next, a description will be given of the work for mowing the upper surface of the ridge by the above mower. First, as shown in FIG. 4, the grass mower of the present invention is for cutting grass grown on the upper surface of the ridge, and specifically, the grass on the upper surface of the ridge is reciprocated once to remove grass up to both ends of the upper surface of the ridge. It is reaping. That is, as shown in FIG. 4, in a state in which the wheels 3 and 3 on the left and right of the machine body 1 are running near the center of the upper surface of the ridge, in front of the wheel 3 on the left side of the machine body, the inside of the cutter housing 13 overhangs a further. By the hammer knife actuated by the rocking motion of each flare 21 ..., the grass on the end side as well as the grass on the center of the ridge can be mowed. Weed the grass at both ends by making one round trip of.

Therefore, since it is not necessary to drive the wheels 3 and 3 to the right and left sides of the upper surface of the ridge, the hammer knife type cutting blade device 11 is overhanged to one side as in the present invention, and the hammer knife type cutting blade device 11 is provided in front of the machine body 1. The lawn mower will be able to prevent slipping off the ridges. It is needless to say that the specific detailed structure and the like can be appropriately changed other than the embodiment. For example, the overhang margin a can be arbitrarily set.

[0014]

As described above, according to the mower of the present invention,
A hammer knife type cutting blade device provided in front of the aircraft with left and right wheels was constructed by overhanging to one side of the aircraft, so that the left and right wheels of the aircraft were running near the center of the ridge upper surface, At, the grass on the edge side of the ridge can also be mowed by a hammer knife type cutting blade device that overhangs on one side of the machine body, therefore,
It is possible to prevent the lawn mower from slipping down from the ridge by eliminating the need for the wheels to run just to the left or right of the upper surface of the ridge.
