New Machine Technology

You asked for the best technology choice to meet the current emissions regulations. John Deere responded by taking a building block approach to meet each new level of emissions standards. We started with our proven Tier 3 technology foundation and added an easy-to-maintain, high-uptime exhaust filter system without the need for a second fluid to meet Interim Tier 4/Stage III B standard. To meet stringent Final Tier 4/Stage IV standards, we're building on our IT4 solution with selective catalytic reduction (SCR) to deliver the best blend of performance, efficiency, and reliability.

Interim Tier 4

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

 

The John Deere Advantage

Exhaust Filter Cleaning


Soot cleaning

We use an exhaust filter made up of a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF) to reduce particulate matter (PM). John Deere engines and exhaust filter components are designed for uninterrupted operation using passive regeneration, a natural cleaning process where engine exhaust temperatures are sufficient to oxidize the PM trapped in the exhaust filter. The process is continuous during normal engine operating conditions — greater than 30 percent load factor — and is the most fuel-efficient way to clean.


If conditions (temperature, load, or speed) for passive regeneration cannot be achieved, then PM must be removed using active regeneration, also an automatic cleaning process. This requires injecting a small quantity of fuel into the exhaust stream for a short duration and elevating exhaust temperatures to clean the filter. It's important to remember that, in most applications, active regeneration cleaning occurs only when passive regeneration isn't possible based on temperature, load and speed. It serves as a backup system. In either case, regeneration does not impact machine operation.

 


Exhaust Filter Servicing

Maintenance to remove accumulated ash is a key system health component of your FT4 exhaust filter. Ash removal from John Deere FT4 machines is condition based, not hour based. The time when this service should actually be performed will be flagged by your machine with a dash indicator or as required by diagnostic codes. Field results on John Deere machines equipped with a DPF have shown this service is often not required until the first major engine overhaul. Actual intervals will be a result of your specific machine application and regular maintenance practices, such as the lube oil used.  Contact your John Deere dealer when ash removal service is required.

 


Fluids and Other Maintenance


Ultra-Low Sulfur Diesel (ULSD)

Only use ULSD fuel in your IT4 engine, and fill your machine at the end of the day to reduce the chances of condensation from overnight cooling. Inspect and maintain fuel filters on the machine and storage tanks. Follow good bulk fuel storage practices. Ask your local dealer for details on fuel specifications and recommendations.


Biodiesel

If you opt to run biodiesel, we suggest using a 5-percent blend (B5), but a biodiesel concentration of up to a 20-percent blend (B20) can be used. All biodiesel must meet ASTM D6751 (U.S.), EN14214 (EU), or equivalent specifications.

Use only our approved fuel additives, found in your operator's manual. Regardless of what fuel or additive you use, frequent fuel sampling and analysis is a good fleet-management practice that we highly recommend.






Image of oil productsLow-ash oil
Use only low-ash CJ-4 oil such as John Deere Plus-50™ II. This oil reduces the ash in your exhaust filter and prolongs intervals between filter ash removal service. We also recommend frequent oil sampling and analysis.





Coolant
Our IT4 machines will notify your operator if the coolant level is low. Use only Cool-Gard™ II antifreeze developed specifically for your IT4 engine.


Engine crankcase filter maintenance
Our earlier-Tier vent tubes have been replaced by open crankcase ventilation systems. No service is required for engines rated above 130 kW (175 hp). For engines rated below 130 kW (175 hp), the open crankcase ventilation system must be serviced every 2,000 hours.

Diesel Exhaust Fluid (DEF)
The best way to ensure you are getting high-quality DEF for your engine or equipment is to purchase DEF through your John Deere dealer. When you buy DEF from Deere, you can be confident you are getting a high-quality product that will provide maximum performance while protecting your engine investment. Other DEF may be used only if it meets certification.


DEF should be stored in a sealed container, in the shade where possible, and out of extreme temperatures. DEF freezes at 12 deg. F (–11 deg. C) but may be used upon thawing. Exposure to high heat for sustained periods can degrade the quality of DEF. When stored properly, DEF has a shelf life similar to oils and coolants. DEF should be crystal clear with a light ammonia smell. If DEF appears cloudy or has a colored tint or a profound ammonia smell, it should not be used.

Hybrid Technology

Technologies like hybrid electrification are rapidly progressing from theory to reality. Hybrid electric technology makes it easier for you to meet a variety of environmentally driven demands. We introduced the 644K Hybrid Loader and 944K Hybrid Loader at the 2011 CONEXPO-CON/AGG show with availability scheduled for 2013.


Definition of Hybrid Electrification Terms


Hybrid electrification means two sources of energy — such as diesel fuel and electricity — are powering a vehicle or equipment. Hybrid-electric technology includes electric traction, auxiliary electrification, energy management, and integrated starter/alternators.


Electric traction involves the engine driving a generator to create the electricity used by an electric motor or motors to drive tracks or wheels. This technology has been applied in our industry for years, like large mining trucks. We are heavily involved in electrification research and development, and have already launched a number of electric drives on our mowers, like our E-Cut Series Mowers.


Auxiliary electrification generates enough electric power to run an attachment or a component of a machine, such as a machine's HVAC or hydraulic pumps.


Energy management shows great promise as battery technology improves and manufacturing costs are reduced, and will soon provide contractors with viable payback on equipment used in repetitive motion applications, such as loaders and excavators.




Benefits of Electric Traction


Productivity

  • Smooth propulsion control
  • Consistent hydraulic performance
  • Faster ramp climbing (in the case of wheel loaders)

 

Uptime

  • Long component life goals
  • Advanced diagnostics/prognostics
  • Redundant systems in some designs

 

Low Daily Operating Cost

  • Lower fuel consumption
  • Reduced tire wear on machines with traction control
  • Fewer wear parts for reduced long-term maintenance cost
