PROBLEM TO BE SOLVED: To solve such a problem such that it is difficult to make a ridge formation-working part go straight forward against the meandering of a traveling machine.SOLUTION: This ridge former equipped with an attaching frame 1, supporting frame 2, controlling part 8, detecting part 7, and ridge formation-working part 5 having a soil-banking part and ridge-forming part, and working by being attached to a traveling machine T, is capable of performing a standard ridge-forming work for forming the ridge R by traveling the traveling machine T in parallel to the ridge R, a separated ridge-forming work for forming the ridge by travelling the traveling machine T with a distance from the ridge R, and a narrowing ridge-forming work of forming the ridge by traveling the traveling machine T while narrowing the distance from the ridge R to make the narrowing traveling, and has a controlling part 8 capable of controlling the posture of the ridge formation-working part 5 automatically as capable of forming the straight line ridge even in the case that the traveling machine T travels while meandering.COPYRIGHT: (C)2009,JPO&INPIT【課題】 走行機の蛇行に対して畦成形作業部を直進させることが困難であった。【解決手段】装着フレーム1と、支持フレーム2と、制御部8と、検知部7と、盛土部及び成畦部とを有する畦成形作業部5とを具備し走行機Tに装着され作業する畦成形機であり、走行機Tが畦Rに平行して走行しながら畦Rを成形する標準畦成形作業と、走行機Tが畦Rとの間隔を離隔走行しながら畦を成形する離隔畦成形作業と、走行機Tが畦Rとの間隔を狭めながら幅寄せ走行しながら畦を成形する幅寄せ畦成形作業とを行なうことができ、制御部8は、走行機Tが蛇行走行した場合であっても畦成形作業部5の姿勢を自動的に直線の畦を成形できる向きに制御可能な畦成形機による。【選択図】 図7
