難であった。このため、刈刃ハウジングの底面が前方に
大きく露出せず、刈刃交換などのメンテナンスに手間が
かかっていた。According to the above-mentioned conventional construction, a portion of the upper surface of the mower's cutting blade housing, which is located forward of the center of gravity of the mower, is connected to the front free end of the lifting link. Because it was supported by lowering, the length from the hanging support point to the rear end of the mower becomes longer, and the rear end of the mower can be easily gripped on the ground side when setting to the maintenance posture,
It was difficult to increase Moore's rise angle from the ground. For this reason, the bottom surface of the cutting blade housing was not largely exposed forward, and maintenance such as replacement of the cutting blade was troublesome.

とで、メンテンス姿勢を維持することができる。The upper part of the mower's cutting blade housing, which is behind the mower's center of gravity, is suspended and supported by being connected to the front free end of the lifting link. The length to the rear end is shortened, and when the mower is artificially inverted to the maintenance posture, the rear end of the mower is difficult to hold on the ground side, and the rising angle of the mower from the ground is increased. Can be. In this case, since the center of gravity of the mower is located forward of the hanging support point,
The mower that has been reversed to the maintenance posture tends to fall to the front side, but by maintaining the posture of the mower by the posture holding unit, the maintenance posture can be maintained.
