- 走行車両に装備されるモーアデッキであって、
天井壁を有するハウジングと、
前記天井壁の下方で、縦軸周りで回転する少なくとも1つのブレードと、
前記ブレードの回転軌跡の外周領域を包囲するように前記天井壁から下方に延びて内部にマルチング用ブレード回転空間を作り出すブレードバッフルユニットと、
を備え、
前記ブレードバッフルユニットは、前記走行車両の前進側に位置する前バッフルと、前記走行車両の後進側に位置する後バッフルとからなり、前記前バッフルは、前記前バッフルの下端からの刈草の排出が阻止されるように、前記天井壁から下方に前記回転軌跡を超えて延設されており、前記後バッフルは、前記天井壁から、前記刈草の放出が可能となるところまで下方に延設されているモーアデッキ。 - 前記後バッフルの下端から前記天井壁までの長さは、前記前バッフルの下端から前記天井壁までの長さより10mm〜30mm短くなっている請求項1に記載のモーアデッキ。
- 前記後バッフルの下端から前記天井壁までの長さは、前記前バッフルの下端から前記天井壁までの長さより、15mm〜25mm短くなっている請求項2に記載のモーアデッキ。
- 前記ハウジングの前縁に設けられた左右一対の接地輪が接地した状態で、昇降リンク機構を介して前記走行車両に吊り下げ支持された草刈姿勢において、前記ブレードの回転軌跡の後端が先端より2mmから12mm高くなるように持ち上げられるように設定可能である請求項1〜3のいずれか一項に記載のモーアデッキ。
- 前記ハウジングの前縁には所定間隔をあけて左右一対の接地輪が設けられており、前記ハウジングの後縁の左右中央位置には単一のスキッドが設けられている請求項1〜3のいずれか一項に記載のモーアデッキ。
- 前記ブレードは平板からなり、前記ブレードの両側の先端から前記縦軸に向かって、ブレード長さの五分の1以上の長さを有するカッティングエッジが形成され、前記カッティングエッジの対向側に三角形状の起風部が立ち上がり折り曲げにより形成されている請求項1〜5のいずれか一項に記載のモーアデッキ。
