PROBLEM TO BE SOLVED: To enable easily switching between tilling work and hilling work in a walking-type tiller capable of performing both tilling work and hilling work and to perform favorable tilling work and hilling work.SOLUTION: A walking-type tiller comprises: tilling tines (10) a tillage upper cover (11) for covering an upper part of the tilling tines (10) hilling plates (20) composed of a rigid flat plate in a shape of a reverse trapezoid seen from the rear and a tilling cover provided with a tillage flattening body (24) at its lower end part. In the walking-type tiller, the hilling plates (20) and the tilling cover are connected to the rear end part of the tillage upper cover (11) rotatably about the lateral axis, and the hilling plates (20) are connected or disconnectably connected with the tilling cover. For tilling work, the hilling plates (20) are connected with the tilling cover for hilling work in which ridges are formed, the hilling plates (20) are disconnected from tilling plates (21) and the tilling cover is turned to an upper flip-up position and secured there.COPYRIGHT: (C)2014,JPO&INPIT【課題】耕耘作業と培土作業を行える歩行型耕耘機において、培土作業と耕耘作業を簡単に切り換えられるようにする。また、良好な耕耘作業や培土作業を行えるようにすることを課題とする。【解決手段】耕耘爪(10)と、耕耘爪(10)の上方を覆う耕耘上部カバー(11)と、背面視で逆台形状の剛性の平板で構成される培土板(20)と、下端部に耕耘ならし体(24)を備える耕耘用カバーとを備え、培土板(20)と耕耘用カバーを耕耘上部カバー(11)の後端部にそれぞれ横軸心に回動自在に連結し、培土板(20)と耕耘用カバーを連結又は連結解除可能に構成し、耕耘作業時は培土板(20)と耕耘用カバーを連結し、畝を形成する培土作業時は培土板(20)と耕耘板(21)の連結を解除すると共に、耕耘用カバーを上方の跳ね上げ位置まで回動して固定する。【選択図】 図1
