PROBLEM TO BE SOLVED: To facilitate switching of a walking type tiller among earthing work, transporting work and tilling work.SOLUTION: A walking type tiller includes a tilling part (K) to till a field, an operating handle (13) extending backward, and wheels (17) freely rotatable at a back of the tilling part (K). The wheels (17) are supported by a supporting member (25), a flat earthing plate (B) is attached to the supporting member (25), and the wheels (17), the supporting member (25) and the earthing plate (B) are integrally tiltable in vertical direction to make the tiller switchable between an earthing work to position the earthing plate (B) between the grounding wheels (17) and the tilling part (K), and tilling work to retreat the wheels (17) and the earthing plate (B) upward and separate the parts from ground.COPYRIGHT: (C)2014,JPO&INPIT【課題】本発明は、培土作業、運搬作業、耕耘作業を切り換え易くすることを課題とする。【解決手段】圃場を耕耘する耕耘部(K)と後方に延びる操作ハンドル(13)を設け、耕耘部(K)の後方に遊転する車輪(17)を設ける歩行型耕耘機において、車輪(17)を支持体(25)で支持する構成とし、支持体(25)には、平面状に形成する培土板(B)を取り付け、車輪(17)と支持体(25)と培土板(B)を一体に上下方向に回動することで、接地状態の車輪(17)と耕耘部(K)との間に培土板(B)が位置する培土作業と、車輪(17)と培土板(B)を上方に退避させて非接地状態の位置とする耕耘作業に、切換可能に構成したことを特徴とする。【選択図】 図5
