PROBLEM TO BE SOLVED: To achieve labor-saving and efficient removal of the topsoil of a ridge.SOLUTION: This ridge topsoil cutting machine 101 is mounted on a tractor 301 to freely rock up and down in use. The ridge topsoil cutting machine 101 includes: a slope soil cutting part 111 for scraping the topsoil of a slope 502 of the ridge topsoil cutting machine 101 and an upper surface soil cutting part 121 for scraping an upper surface scraper 131 of a ridge 501. The slope soil cutting part 111 is caused to move up and down along the ground surface by a gauge wheel 408AA provided on the machine frame of the ridge topsoil cutting machine 101. A second rotating shaft 122 of the slope soil cutting part 121 is located above a first rotating shaft 112 of the slope soil cutting part 111, and provided on the machine frame to move up and down independently of the first rotating shaft 112. The power output from the tractor 301 rotates the first rotating shaft 112 of the slope soil cutting part 111 and the second rotating shaft 122 of the upper surface soil cutting part 121, whereby a first digging claw 113 and a second digging claw 123 are caused to scrape the topsoil of the ridge 501.COPYRIGHT: (C)2013,JPO&INPIT【課題】畦畔の表土を省力的かつ効率的に取り除く。【解決手段】畦畔表土削り機101は、トラクタ301に上下揺動自在に装着されて用いられる。畦畔表土削り機101は、畦畔表土削り機101の傾斜面502の表土を削り取る傾斜面削土部111と、畦畔501の上面スクレーパー131を削り取る上面削土部121とを有する。傾斜面削土部111は、畦畔表土削り機101の機枠に備えたゲージ輪408AAにより地表面に沿って上下動する。上面削土部121の第2回転軸122は、傾斜面削土部111の第1回転軸112よりも上方に位置するものであり、第1回転軸112とは独立して上下動するよう機枠に設けられる。トラクタ301から出力された動力は、傾斜面削土部111の第1回転軸112や上面削土部121の第2回転軸122を回転させ、第1掘削爪113や第2掘削爪123に畦畔501の表土の削り取りを行わせる。【選択図】図3
