PROBLEM TO BE SOLVED: To provide a power supply notification system of an agricultural machine for notifying of a power supply state when supplying power to a working machine mounted on a tractor for performing agricultural work through wireless power supply.SOLUTION: A power supply notification system includes a power transmission unit 14 installed on a tractor 1 side, a power receiving unit 21 installed on a working machine 2 side, a working machine side radio unit 22 installed in the working machine 2 to which power can be supplied from the power receiving unit 21, a power storage unit 23 installed in the working machine 2 that can store power by the power from the power receiving unit 21, a control unit 24 installed in the working machine 2, an actuator 27 installed in the working machine 2 to which power is supplied from the power storage unit 23, and a first notification unit 45 installed in the working machine 2. Wireless power supply can be made from the power transmission unit 14 to the power receiving unit 21. The first notification unit 45 performs notification when the wireless power supply is made from the power transmission unit 14 to the power receiving unit 21.SELECTED DRAWING: Figure 1【課題】トラクタに装着して農作業を行う作業機へワイヤレス給電を介して給電するときの給電状態を報知する農作業機の給電報知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１側に設置される送電部１４と、作業機２側に設置される受電部２１と、作業機２に設置され受電部２１から電力が供給可能な作業機側無線部２２と、作業機２に設置され受電部２１からの電力により蓄電が可能な蓄電部２３と、作業機２に設置される制御部２４と、作業機２に設置され蓄電部２３から電力が供給されるアクチュエータ２７と、作業機２に設置される第１の報知部４５とを有し、送電部１４から受電部２１へはワイヤレス給電が可能であり、第１の報知部４５は、送電部１４から受電部２１へワイヤレス給電がされている場合の報知をする。【選択図】図１
