PROBLEM TO BE SOLVED: To solve such a problem that when the stem of a leaf vegetable such as spinach is cut by a reaping blade and only its leaf part is harvested, even weeds are reaped by the reaping blade when the weeds grow in a field, a large amount of weeds are mixed in a leaf vegetable part and a subsequent weed removal operation takes a long time.SOLUTION: In the leaf vegetable harvester with which the reaping blade 31 for cutting the stem Yb of a leaf vegetable Y cultured in a field is arranged at the front end position of a machine body frame 2 installed on a traveling apparatus 1 and a conveyor belt 41 for placing each leaf part Ya cut by the reaping blade 31 and conveying the leaf part to the rear side of the machine body frame is arranged on the machine body frame 2. The reaping blade 31 has a length to simultaneously cut the leaf vegetable Y cultivated in a field for each a plurality of right and left rows and is equipped with a weed pressing plate 70, which is brought into sliding contact with a field surface and pushes down weeds Z growing on an interrow space of each leaf vegetable line before the reaping blade 31 reaches the weeds at the front position of the machine body frame 2. Consequently, weeds growing on the interrow space of leaf vegetable in a field are not reaped.COPYRIGHT: (C)2009,JPO&INPIT【課題】ホウレン草のような葉菜の茎部を刈刃で切断してその葉部のみを収穫する場合に、圃場に雑草が生えていると該雑草まで刈刃で刈り取ってしまい、多量の雑草が葉菜葉部中に混入して、後の雑草排除作業に長時間がかかる。【解決手段】走行装置1上に設置した機体フレーム2の前端位置に圃場に栽培している葉菜Yの茎部Ybを切断し得る刈刃31を設け、機体フレーム2に刈刃31で切断した各葉部Yaを乗せて機体フレーム後方側に搬送するコンベアベルト41を設置した葉菜収穫機において、刈刃31は、圃場に栽培している葉菜Yを左右複数条ずつ同時に切断し得る長さを有しているとともに、機体フレーム2の前部位置に圃場面に摺接して各葉菜列の条間に生えている雑草Zを刈刃31が達する前に押し倒すことができる雑草押え板70を設けていることにより、圃場の葉菜条間に生えている雑草を刈り取らないようにしている。【選択図】 図4
