Abstract:
A forestry machine includes a frame, and a felling saw carried by the frame. The felling saw includes a saw head. A tree counter associated with the saw head includes an audio sensor providing an output signal representing an audio parameter associated with a cutting action of the saw head. An electrical processing circuit is coupled with and receives the output signal from the audio sensor. The electrical processing circuit determines a tree count associated with the saw head, dependent upon the output signal from the audio sensor.
