PROBLEM TO BE SOLVED: To provide an agricultural implement not causing trouble in engagement between a fitting part on either one side and a fitting part on the other side and capable of adequately changing over a folding operation part to a desired developing operation state.SOLUTION: An agricultural implement 1 is equipped with a central operation part 2 and an extending operation part 3 rotating to the central operation part 2. A leveling body 8 of the central operation part 2 has one-side fitting parts 33 and 43 in which the cross section is nearly U-shaped. One-side fitting parts 33 and 43 are only composed of side plate parts 31 and 41 and opposite plate parts 32 and 42 protruded from these side plate parts 31 and 41. An extending leveling body 53 of the extending operation part 3 has the other-side fitting parts 77 and 81 fitting to the one-side fitting parts 33 and 43 in developing operation state.COPYRIGHT: (C)2010,JPO&INPIT【課題】一方側嵌合部と他方側嵌合部との嵌合に不具合が生じず、折畳作業部を所望の展開作業状態に適切に切り換える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、中央作業部2と、この中央作業部2に対して回動する延長作業部3とを備える。中央作業部2の整地体8は、断面略コ字状の一方側嵌合部33,43を有する。一方側嵌合部33,43は、側板部31,41およびこの側板部31,41から突出する対向板部32,42のみにて構成する。延長作業部3の延長整地体53は、展開作業状態時に一方側嵌合部33,43と嵌合する他方側嵌合部77,81を有する。【選択図】図1
