Interim Tier 4/Stage III B technology

Right technology. Right now.

John Deere chose EGR with an exhaust filter to meet Interim Tier 4/Stage III B emissions regulations. Our approach uses cooled exhaust gas recirculation (EGR) for NOx reduction and an integrated exhaust filter for particulate matter (PM) reduction. It is simple to install, operate, and maintain while delivering the power, fluid efficiency, reliability, and low cost of ownership you've come to expect from John Deere.
