We recognize the importance of biofuels to our customers and to the environment. Use of quality biodiesel in John Deere diesel engines has economic and environmental benefits, boosts development in rural areas, and helps provide energy security. Other advantages of quality biodiesel include improved lubricity, reduced sulfur emissions, and reduced aromatics. Biodiesel has a high cetane content for faster ignition. It also produces less visible smoke and lowers the amount of particulate matter, hydrocarbons, carbon monoxide, and life-cycle carbon dioxide emissions produced by an engine.
