At John Deere, we take our responsibility to the environment very seriously, and we took steps to monitor and reduce emissions before government regulations were ever set. We have never wavered in this commitment. John Deere emissions technology includes air-to-air intercooling, increased fuel injection pressure, a more efficient combustion bowl, guide seals, and more. Best of all, we’ve proven that you don’t have to sacrifice performance to meet regulations. John Deere engines apply the appropriate level of emissions technology while improving performance, increasing reliability, and reducing maintenance costs.
