[0094]

The present invention is embodied in the form described above, and has the following effects.

(1) According to the first aspect of the present invention, since the mowing device is provided on the bogie traveling on the work rail,
The mowing operation can be performed while moving the mowing device along the work rail, and the mowing height can be adjusted according to the height of the work rail. Can be improved.

(2) According to the second aspect of the present invention, since the mowing device is mounted on the bogie so as to be movable in a direction substantially orthogonal to the work rail, the mowing device can be small even if the mowing device is small. By moving the device on the trolley, the grass planted between the opposing work rails can be evenly cut. Therefore, it is possible to reduce the size of the mowing device and to reduce the weight of the bogie.

(3) According to the third aspect of the present invention, a transport vehicle is disposed at the end of the work rail, and the transport vehicle is configured such that a truck can be mounted on the upper portion thereof. For example, when mowing grass planted on a slope of a saw-shaped roof, a work rail is attached to each slope, and a mowing device is installed. By moving the truck provided between the adjacent work rails by the carrier, the mowing operation can be performed smoothly and easily.

Moreover, mowing can be performed by remote control, and a control device in which a series of operations are programmed in advance can be provided in the mowing machine, so that all mowing can be automatically performed. .

(4) According to the present invention, a bogie moving means for moving the bogie along a work rail is provided on the bogie, and the mowing device is provided with a bogie moving device. Since the mowing device moving means for moving the mowing device in a direction substantially orthogonal to the rail for use is arranged, the bogie and the mowing device can be moved independently, and complicated movement of the bogie and mowing device can be achieved. It can be done easily.

Further, the weight balance between the bogie and the mowing device can be improved, and the weight of the mowing device can be reduced as much as possible. Motor and the like can be small.
