PROBLEM TO BE SOLVED: To provide a compact tiller capable of performing tilling work and ridging work.SOLUTION: The tiller includes a ground resistance bar 14 vertically passing through a tilling rotor cover 13 and also vertically passing through the rear side of a tilling rotor 12, a rubber-made ridging plate 22 whose upper end part is supported at the rear end part of the tilling rotor cover 13 and stretched over in the horizontal direction and whose lower end side is hung down to the rear side of the tilling rotor 12 and the ground resistance bar 14, and a ridging plate supporting part 21b supporting and acting at the central part in the ridging plate width direction of the lower end of the ridging plate 22 so that the movement to the rear side, caused by work reaction of the lower end of the ridging plate 22 is suppressed to maintain the ridging plate 22 to be acting state.COPYRIGHT: (C)2010,JPO&INPIT【課題】耕耘作業も培土作業も行なうことができる耕耘装置をコンパクトな状態で得る。【解決手段】耕耘ロータカバー13を上下方向に貫通するとともに耕耘ロータ12の後側を上下方向に通る接地抵抗棒14を備えてある。耕耘ロータカバー13の後端部に上端部が横幅方向に亘って支持されて、下端側が耕耘ロータ12及び接地抵抗棒14の後方に垂れ下がるゴム板から成る培土板22を備えてある。培土板22の下端部の作業反力による後方側への移動を抑制して培土板22を作用状態に維持するように培土板22の下端部の培土板横幅方向での中央部に支持作用する培土板支持部21bを備えてある。【選択図】図3
