PROBLEM TO BE SOLVED: To provide a continuous levee-reshaping operation method for a levee plastering machine, which improves the efficiency of continuous levee plastering operation from one ridge to the next.SOLUTION: Once a traveling machine body reaches a corner part of a farm field, an operation part 50 performs a straight levee-reshaping operation to a ridge of the farm field in an automatic straight-traveling operation control mode in which the operation part 50 operates in a straight line while adjusting the position and direction of the operation part 50. From an end edge to an adjacent ridge, by using an operation position at the end of the straight traveling operation control mode as a starting position, in a corner-part arc finishing operation control mode in which the operation part 50 operates in an arcuate line at an unfinished portion remaining in the corner part of the farm field, the operation part 50 performs a curved levee-reshaping operation continually. From a start edge to an end edge of an adjacent ridge where the traveling machine body is located away from the ridge, the operation part 50 performs the straight levee-reshaping operation in a levee-gathering traveling control mode when the traveling machine body approaches the next ridge side.COPYRIGHT: (C)2014,JPO&INPIT【課題】畦から次の畦までの連続的な畦塗り作業の能率が上がる畦塗り機の連続整畦作業方法を提供する。【解決手段】圃場の隅部に走行機体が到達すると、作業部50の位置、方向の変化を調整しながら作業部50が直線作業する自動直進作業制御モードにて作業部50が圃場の畦に対し直線整畦作業を行い、その終端部から隣り合う畦の始端部にかけては直進作業制御モードの終了時の作業位置を起点とし、圃場隅部に残存する未作業部分を円弧状に作業する隅部円弧仕上げ作業制御モードにて作業部50が曲線整畦作業を継続して行い、走行機体が畦から離れた位置に位置する隣り合う畦の始端部から終端部にかけては走行機体の次の畦側への接近時に直線作業する畦寄せ走行制御モードにて作業部50が直線状整畦作業を行う。【選択図】 図7
