diesel-powered products. This announcement is just the latest step in John Deere's ongoing 35-year commitment to the 

development of bio-based alternative fuels that benefit both the environment and the agricultural community.  "We're

excited to be able to support the use of Biodiesel in our products,"notes Ted Breidenbach, Manager of Worldwide Engine

Engineering for John Deere Power Systems. "Biodiesel is a valuable tool for helping reduce engine emissions. It also

stands as one of the linchpins in the movement to develop alternative uses for commodity products that can ultimately

deliver more value to our producer customers.  "The quality of Biodiesel as a fuel source has improved tremendously in

recent years, "Breidenbach adds. "We're confident that when it's used per factory specifications it will generate the 

performance producers have come to expect from their John Deere equipment."After thorough testing and analysis John 

Deere engineer have developed the following guidelines to help ensure optimum use of Biodiesel:

* Customers should consult with their local fuel suppliers to be sure the Biodiesel fuel meets the ASTM PS

  121-99 or DIN 51606 fuel specifications.

* Biodiesel, by definition is biodegradable, so the higher the concentration of Biodiesel in a fuel blend, the

  more susceptible the fuel is to degradation and water absorption. While rapeseed methyl ester (RME)

  concentrations up to 100% have been run successfully, concentrations of up to five percent Biodiesel have

  shown improvement in fuel lubricity while minimizing the potential problems associated with fuel  

  degradation.

* Operators should keep storage and vehicle tanks as full as possible to prevent moisture. Storage tanks

  should be protected from extreme temperatures and extended storage of Biodiesel fuel should be limited.

  Routine monitoring of the fuel's water content is also recommended.  Following these guidelines will ensure

  normal warranty coverage on products fueled by Biodiesel blends.

* John Deere will continue to support further development and use of Biodiesel and additional alternative uses

  for agricultural commodities. This commitment is evident in the company's support of renewable fuels

  legislation and in John Deere's ongoing exploration and use of soy-based resins to replace sheet metal on

  products. An example of this technology is the HarvestForm panels that will be used on John Deere Combines

  built in 2002. These panels are made from a special polymer derived from corn and soybeans.  "These are

  exciting technologies that will have long-term benefits for producers, consumers and every citizen with

  environmental concerns,"Breidenbach says.  Biodiesel can also be used in older model tractors and engines.

  Please check with your local John Deere dealer or fuel supplier for details. One of the world's oldest and

  most respected enterprises, John Deere

* Users of John Deere Emission Certified Engines, are responsible for obtaining any appropriate local, state,

  and national exemptions required for the use of Biodiesel.
