PROBLEM TO BE SOLVED: To provide a farm working machine capable of performing proper offset work.SOLUTION: A ridge plastering machine 10 of a farm working machine has a fixing machine frame 11 for connecting to the rear part of a tractor T. The front end part of an extendable rotator 21 is connected to the fixing machine frame 11 rotatably around a vertical first rotation center axis X1. A movable machine frame 22 is connected to the rear end part of the rotator 21 rotatably around a vertical second rotation center axis X2. A ridge plastering means 23 is mounted on the movable machine frame 22. When progressing and turning the tractor T on the corner of the farm field, the ridge plastering means 23 moves linearly forward and concurrently performs ridge plastering work based on rotation of the rotator 21 to the fixing machine frame 11, expansion and contraction of the rotator 21 and rotation of the movable machine frame 22 to the rotator 21.COPYRIGHT: (C)2008,JPO&INPIT【課題】適切なオフセット作業ができる農作業機を提供する。【解決手段】農作業機である畦塗り機10は、トラクタTの後部に連結する固定機枠11を備える。固定機枠11に伸縮可能な回動体21の前端部を上下方向の第1回動中心軸線X1を中心として回動可能に連結する。回動体21の後端部に可動機枠22を上下方向の第2回動中心軸線X2を中心として回動可能に連結する。可動機枠22には畦塗り手段23を設ける。圃場の隅部におけるトラクタTの前進旋回時に、固定機枠11に対する回動体21の回動と回動体21の伸縮と回動体21に対する可動機枠22の回動とに基づき、畦塗り手段23が前方に向って直線状に移動しながら畦塗り作業をする。【選択図】図1
