PROBLEM TO BE SOLVED: To provide a farm implement capable of preventing failure of a subsoil crushing body and smoothly returning the subsoil crushing body to the original working state by a plurality of forcing bodies.SOLUTION: The farm implement 1 is equipped with an implement body 5 connected to a tractor, a tilling unit 11 installed to the implement body 5, and a land grading body 16 installed to the implement body 5. The subsoil crushing body 30 is installed to be rotatable upward and downward to a subsoil crushing body-attaching part 31 of the implement body 5. A plurality of coil springs 41 for forcing the subsoil crushing body 30 are arranged on both left and right sides of the subsoil crushing body-attaching part 31. The forcing force of each coil spring 41 can be individually adjusted.COPYRIGHT: (C)2010,JPO&INPIT【課題】心土破砕体の破損を防止でき、複数の付勢体にて心土破砕体をもとの作業状態にスムーズに戻すことができる農作業機を提供する。【解決手段】農作業機1は、トラクタに連結する作業機本体5と、作業機本体5に設けた耕耘体11と、作業機本体5に設けた整地体16とを備える。作業機本体5の破砕体被取付部31には心土破砕体30を上下回動可能に取り付ける。破砕体被取付部31の左右両側方には心土破砕体30を下方に向けて付勢する複数のコイルばね41を配設する。各コイルばね41の付勢力がそれぞれ個別に調整可能である。【選択図】図1
