Grass collecting mechanism and mower

The invention discloses a grass collecting mechanism and a mower. Comprising a grass collecting frame and at least one conductive detection sensor, and the conductive detection sensor is used for detecting whether the grass collecting frame is full; the conductive detection sensor comprises a detection unit and a processing unit, and the detection unit is arranged at the top of the grass collecting frame and used for being electrically connected with cut grass; the processing unit is electrically connected with the detection unit and used for judging whether the detection unit is electrically connected with the cut grass or not. According to the device, the detection unit is arranged in the grass collecting frame, when the grass collecting frame is not full of grass, the detection unit is in a disconnected state, as the grass in the grass collecting frame is more and more and reaches the top of the grass collecting frame, due to the electrical conductivity of the grass, the detection unit is conducted through
