In this article, we will explore the history of DEF in John Deere tractors.

What is DEF and Why is it Important?

DEF is a solution made up of urea and deionized water that is injected into the exhaust stream of a diesel engine. It helps to reduce harmful nitrogen oxide (NOx) emissions that are produced during the combustion of diesel fuel. With the implementation of DEF, John Deere tractors meet the strict EPA Tier 4 emissions regulations. DEF is important because it helps to reduce the environmental impact of diesel engines and improves air quality.

The Year John Deere Put DEF on Tractors

John Deere started using DEF on their Tier 4 engines in 2011. They were one of the first companies in the agricultural industry to adopt the use of DEF in their tractors. The first John Deere models to use DEF were the 9R, 9RT, and 9RX tractors. These tractors were equipped with John Deere's Selective Catalytic Reduction (SCR) system, which uses DEF to reduce emissions.

The Benefits of Using DEF in John Deere Tractors

The use of DEF in John Deere tractors offers a number of benefits. Firstly, it helps to reduce harmful emissions, making John Deere tractors more environmentally friendly. Secondly, it improves fuel efficiency and engine performance. By using DEF, John Deere tractors are able to optimize engine combustion and reduce engine wear, resulting in longer engine life. Lastly, the use of DEF helps to reduce maintenance costs. John Deere tractors using DEF require less frequent oil changes and have longer service intervals.

Conclusion

In conclusion, John Deere put DEF on their tractors in 2011. This was a significant move in the agricultural industry, as John Deere was one of the first companies to adopt the use of DEF. The use of DEF in John Deere tractors brings about a number of benefits, including reduced emissions, improved fuel efficiency, and reduced maintenance costs. As we move towards a more environmentally conscious future, the use of DEF in tractors is likely to become more common.
