New John Deere Mid-Frame E-Series Skid Steer Loaders and Compact Track Loaders Meet Final Tier 4 Requirements

In December, John Deere began shipping new mid-frame models in the E-Series line of skid steer loaders and compact track loaders.

Let’s look under the hood to see how these machines meet emissions requirements:

The Yanmar Final Tier 4 diesel engines feature cooled exhaust gas recirculation (EGR) with an exhaust filter consisting of a diesel oxidation catalyst (DOC) and diesel particulate filter (DPF). Unlike larger FT4 engines (for machines >75hp), these smaller machines do not require a selective catalytic reduction (SCR) system as an additional element. That also means that diesel exhaust fluid (DEF) is not required.

Operators will find that there is very little impact to machine operation under most conditions. Periodic DPF cleaning to oxidize soot happens automatically while the machine continues to operate. Ash service intervals for the DPF are condition based, meaning that the machine will inform the operator when service will be required. Machine application, regular maintenance practices, and type of lubricating oil may impact length of those intervals.
