PROBLEM TO BE SOLVED: To provide a guide system for an agricultural implement capable of more appropriately guiding an operation of an implement mounted on a tractor and capable of performing a forward operation and a backward operation.SOLUTION: In a system for guiding an implement mounted on a tractor for performing agricultural work, the implement 50 can be changed at least to a forward operation state and to a backward operation state. Based on the information of position detection means 11, movement distance detection means 12, stop detection means 12, direction detection means 13, posture detection means 12, and operation state detection means 14 and 15, a control unit 20 causes a display unit 26 to display a guide on an operation from a forward operation completion position to a backward operation start position.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】トラクタに装着して前進及び後進作業が可能な作業機の操作の案内をより的確に行うことが可能な農作業機用案内システムを提供することを目的とする。【解決手段】トラクタに装着して農作業を行う作業機を案内するシステムであって、作業機50は少なくとも前進作業状態と後進作業状態に変更可能であり、制御部20は、位置検知手段11と移動距離検知手段12と停止検知手段12と方位検知手段13と姿勢検知手段12と作業状態検知手段14、15の情報に基づいて、表示部26に、前進作業終了位置から後進作業開始位置までの操作の案内をする表示をさせる。【選択図】図1
