４下方から風が逃げるのを防止する。 The bottom wall portion of the plate 24 serves as a wind guide portion 25 located below the cutter 6, and guides the wind generated by the blade portion 10 upward to guide the wind through the plate 2.
4. Prevent wind from escaping from below.
尚、第４図の仮想線で示すように、プレート２
４の天壁部及び風案内部２５を傾斜状とすること
もある。 Furthermore, as shown by the imaginary line in Fig. 4, the plate 2
The top wall section 4 and the wind guide section 25 may be inclined.
上記のように構成した実施例によれば、補強部
材９には、上方突出状とされて補強部材１９を補
強する上方突出部２１を形成しているので、補強
部材１９の強度は大であつて、モアーデツキ５の
前壁部１４及び左側壁部１９を剛強に補強でき
る。 According to the embodiment configured as described above, since the reinforcing member 9 is formed with the upwardly projecting portion 21 which is shaped to project upward and reinforces the reinforcing member 19, the strength of the reinforcing member 19 is high. Thus, the front wall portion 14 and left side wall portion 19 of the mower deck 5 can be strongly reinforced.
又、補強部材１９においては、石等の障害物と
