John Deere Engineers and Equipment Progress

In 1837 John Deere began the quest to build the best equipment on the planet, and current JD engineers continue to pursue that passion. The John Deere team continues to move towards a cleaner and more efficient future with continuous emissions testing’s and improvements. In fact, product testing reports can be accessed weekly at John Deere’s Straightforward Blog.

John Deere Heavy Equipment News

Last month we shared results of the Nebraska Tractor Tests, which demonstrated superior performance from the engine featured in the John Deere IT4 744K wheel loader, proving that emissions reductions and fuel efficiency can go hand in hand.

This month we are proud to share the results of an internal test* showing the same excellent fuel efficiency and productivity from another John Deere machine, the IT4-certified 850K Crawler Dozer.

4 Fluids That Can Impact Interim Tier 4 Engine Efficiency

John Deere Engine Efficiency

In our recent post on Total Fluid Economy we discussed the importance of considering total fluid consumption (diesel fuel plus diesel exhaust fluid) in your purchase of Interim Tier 4-certified equipment. But it’s also important for owners and operators to understand that they must carefully evaluate not only the quantities of fluids consumed, but also the type and quality of fluids they utilize. When it comes to fluid quality, there are four key factors to be aware of:

John Deere Interim Tier 4

Are you new to the “Tier 4” conversation? You’re not alone.  Although the EPA has established and enforced emissions requirements in the form of “Tiers” since 1996, the biggest cuts in emissions are just a few years away from being enforced, bringing a surge of conversation and concern for the off-highway industry.  Interim Tier 4 (IT4) has become the hot topic recently and discussions regarding Final Tier 4 emissions standards will begin to rise to the surface in the coming months.

Interim Tier 4 Alert – Use Only ULSD For IT4 Machines

ULSD For IT4 Machines

A handful of recent diesel fuel samples across the United States underscores the importance of using only Ultra-Low-Sulfur Diesel (ULSD) on Interim Tier 4 machines.

Although the U.S. EPA has required large refiners and importers to produce only non-road diesel fuel with 15 ppm or less sulfur content since June of 2010, this requirement does not apply to small refiners. They are currently required to supply only Low-Sulfur Diesel (LSD). The maximum sulfur content for LSD is 500 ppm. The smaller refiners are not subject to the ULSD requirement until June 2014. Non-road diesel with sulfur content over 500 ppm from all suppliers is prohibited by the EPA.

Interim Tier 4 Engines Put to the Test

John Deere Testing

You could call the Nebraska Tractor Test Laboratory the Consumer Reports of the tractor industry.  As the designated official OECD agricultural tractor testing station for the United States, the lab conducts tractor performance tests and publishes credible and usable tractor performance data.

The tractors tested at the Nebraska lab are often powered by the same engines used in off-highway construction equipment. This makes the Nebraska tests somewhat of a bellwether for the construction equipment industry, providing customers with insights as to how their Interim Tier 4 (IT4) engine will perform when it comes to power, efficiency and total fluid economy.

Exhaust Filter Service Intervals: What to expect on your job site

John Deere Servicing

Many contractors who are beginning to educate themselves on the impacts of Interim Tier 4 (IT4) are expecting ash removal every 3,000 or 4,500 hours depending on engine horsepower for the diesel particulate filter (DPF) component of their non-road diesel exhaust filters. Those are the figures most often quoted in IT4 literature because those are the minimum maintenance intervals required by the U.S. EPA.

Passive Regeneration

In June, we revisited exhaust filter regeneration in a post titled “Exhaust Filter Cleaning: A Return to Basics.” Now that you have a better handle on the fundamentals, let’s take a closer look at the process — starting with passive regeneration.

Four Reasons Why CJ-4 is the Best Oil for Interim Tier 4 Engines Using Exhaust Filter Technology

Earlier this week, we dove into the issue of engine oil choices for John Deere Interim Tier 4 engines. We provided a list of key terms to know when navigating the engine oil decision, and provided John Deere’s best practice recommendation for your engine: Using CJ-4 oil grades to extend service life and maximize efficiency and performance.

Today we expand on the role of engine oil in Interim Tier 4 engines. Here are four reasons why CJ-4 oil grades are the best choice for your new Interim Tier 4 equipment:
