PROBLEM TO BE SOLVED: To provide a ridge-forming machine which has a ridge-forming tool for forming ridges with soil tilled with a rotary tiller located behind the tiller, has a gauge body which contacts a field for supporting machine frame load, is attached to the rear portion of a travel member, is moved on a field, forms a ridge on the field, can repair the collapsed upper side of the formed ridge, when forming a ridge adjacent to the formed ridge, while partially overlapping on the ridge formed, and can efficiently ensure the press force of an upper side-forming tool for the upper side of the ridge.SOLUTION: This ridge-forming machine includes an upper-side forming tool 66 for repairing the collapsed upper side Ra of the formed ridge R2, and disposes the upper-side forming tool 66 on a support member 67 which is erected vertically on the gauge body 37, when the ridge R1 is to be formed adjacent to the formed ridge R2, while making a part of it partially overlap the formed ridge R2.COPYRIGHT: (C)2009,JPO&INPIT【課題】 ロータリ耕耘装置の後方に、該ロータリ耕耘装置で耕耘された土で畝を成形する畝成形具を備えると共に、この畝成形具の側方に圃場に接地して機体荷重を支えるゲージ体を備え、走行体の後部に装着されて圃場を移動しながら該圃場に畝を成形する畝成形機において、既成形畝に一部オーバーラップさせながら該既成形畝に隣接する畝を成形する際に、前記既成形畝の、崩された側の上面を修復することができ、しかも、畝上面に対する上面成形具の押え力を十分に確保できる畝成形機を提供する。【解決手段】 既成形畝R2に一部オーバーラップさせながら該既成形畝R2に隣接する畝R1を成形する際に、前記既成形畝R2の、崩された側の上面Raを修復する上面成形具66を設け、この上面成形具66を、前記ゲージ体37に立設された支持体67に設ける。【選択図】図1
