Abstract: An agricultural harvester includes a chassis; at least one ground engaging traction member held by the chassis; a cutter held by the chassis; a sensor held by the agricultural harvester so that the sensor is directed in front of the cutter and configured to emit and receive sound and/or radio waves and produce a plurality of output signals; and an electrical processing circuit coupled to the sensor. The electrical processing circuit is configured to produce a field map from the plurality of output signals and adjust an operating parameter of the agricultural harvester based on the field map.

Abstract: The present invention provides a vibration dampening laminate that is lightweight and has superior sound insulation and vibration dampening properties. The vibration dampening laminate comprises a constraining layer, a viscoelastic adhesive layer, a foam spacing layer and a pressure sensitive adhesive layer including a release layer. The pressure sensitive adhesive layer and release layer are contoured to fit a profile of the article being soundproofed and vibration dampened.
