(C) Problems to be Solved by the Invention However, with the snow plow having such a structure, the scraping device blocks the front in the direction of movement, so that the worker operating the snow removal device at the rear of the snow removal device cannot perform the work in front. There is a risk of colliding with obstacles on the work path and damaging the machine, making it difficult to perform snow removal operations that match the snow conditions, and the scraping device is Although it is difficult to adjust the tilt,
In order to fix the tilting state between the support rod and the frame,
The inclination can be finely adjusted, and the #4 rib can be operated with just one hand.
The work was complicated and had to be done manually, and it had drawbacks such as the inability to immediately perform tilting operations depending on snow conditions during scraping work.
