The operation and effect of the present invention will now be described with reference to FIG.
To start mowing while rotating the rotary blade C and swinging it to the left and right. Then, when there is only one side grass without any obstacle, the tentacle bar 2 does not work, and the grass is cut into the rotary blade C without any trouble as a result of the wings being spaced apart from each other in a wing-like manner from the front. Now, when there are obstacles such as hard stones in the grass, the tentacle bar 2 first touches them to notify them of approach, so that direct contact and collision with the rotary blade C can be avoided, and the rotary blade C itself can be avoided. Is prevented from being damaged. When the ground is hard, the substantially elliptical frame 1 and the tentacle bar 2 prevent direct contact between the rotary blade C and the ground, and the rotary blade C itself is similarly protected. On the other hand, when working in the vicinity of a tree or a building, the tentacle action of the tentacle bar 2 prevents damage by the rotary blade C.

The protective tentacle attachment is provided with a height adjustment holder 8 and an angle adjustment holder according to the situation at the work site.
By changing the positions of the mounting screws 6 and 7 in 9, the distance (height) from the rotary blade C and the inclination with respect to the rotary blade C are adjusted.
