Final Tier 4/Stage IV technology

Delivering our customer's expectations
We understand your concerns about Final Tier 4/Stage IV emissions regulations. That's why we're focused on adding the right engine technologies at the right time to maintain and maximize performance. This smart approach to meeting emissions regulations doesn't compromise on power, reliability, or ease of operation.

Meeting emissions while maximizing performance

You don't have to sacrifice one for the other. John Deere PowerTech™ Final Tier 4/Stage IV engines, 56 kW (75 hp) and above, are built on a proven platform of emissions control technologies including cooled exhaust gas recirculation (EGR), exhaust filters, and selective catalytic reduction (SCR).

Countless hours of testing in labs, field prototype machines, and in the toughest proving ground of all — rugged off-highway applications — have shown that John Deere engines have what it takes to get the job done.


Performance, reliability, and durability

These three words capture the core of the John Deere engine experience. You can count on John Deere engines to deliver reliable power day in and day out, year after year, and in the toughest off-highway working conditions. John Deere Final Tier 4/Stage IV engines maintain power density, torque, and transient response. It all adds up to more productivity, uptime, and value for your machines.
