PROBLEM TO BE SOLVED: To provide an agricultural implement capable of avoiding giving of unrest to an operator riding the agricultural implement or to a monitor outside the agricultural implement.SOLUTION: An automatically-travelable agricultural implement includes a vehicle speed setting part 24a capable of setting an individual target vehicle speed relative to the state of an automatically-traveling machine body, and a vehicle speed control part 24b for controlling the vehicle speed based on the target vehicle speed set by the vehicle speed setting part 24a. The vehicle speed control part 24b makes the vehicle speed asymptotic to changed vehicle speed which is a target vehicle speed corresponding to the changed state of the machine body, upon change of the state of an automatically-traveling machine body.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2020,JPO&INPIT【課題】農作業機に搭乗しているオペレータや農作業機の外部の監視者に不安感を与えることを回避できる農作業機を提供する。【解決手段】自動走行可能な農作業機であって、自動走行中の機体の状態毎に個別の目標車速を設定可能な車速設定部24aと、車速設定部24aにより設定された目標車速に基づいて車速を制御する車速制御部24bと、を備え、車速制御部24bは、自動走行中における機体の状態の変化時に、変化後の機体の状態に対応する目標車速である変化後車速に車速を漸近させる。【選択図】図5
