Abrégé

Provided is a walk-behind self-propelled working machine. The walk-behind self-propelled working machine includes a main body, an operation switch, and a handle device. The main body includes a moving assembly and a drive motor configured to drive the moving assembly. The operation switch is connected to the drive motor. The handle device is connected to the main body and includes an operation member, a connecting rod, and a sensing module. The operation member includes a gripping portion for a user to hold. The connecting rod is connected to the main body. The sensing module is configured to sense a thrust that is applied to the handle device to drive the walk-behind self-propelled working machine and further includes a pressure sensor and a pressing member. The pressure sensor is disposed between the operation member and the connecting rod. When the gripping portion receives the thrust, the pressing member applies a force along a preset straight line to the sensor to drive the pressure sensor to deform.
