New Holland CR9.90 Elevation vs. John Deere S690 PAMI Results

New Holland commissioned the Prairie Agricultural Machinery Institute (PAMI) to conduct independent combine productivity comparison tests on Model Year 2015 New Holland CR9.90 Elevation and John Deere S690 combines.

PAMI has 40 years of experience testing harvesting equipment in various locations worldwide with a specialty in Western Canadian crops and conditions. The combines were tested in September 2015 in wheat and canola in Saskatchewan. Testing focused on harvesting productivity and fuel consumption efficiency.

Summary of Results:

  • New Holland has a 4% better harvesting productivity in wheat and up to 10% in canola.
  • The CR Elevation combine harvested 9% more grain per gallon of fuel and DEF than Deere S690.
  • There is an incredible difference of 13% gallons of fuel per acre in wheat and a 9% difference in the canola. On a 5,000-acre farm with 2,500 acres of wheat and 2,500 acres of canola, this would translate to a savings of up to $18,000 CAD per year (or approximately $13,000 USD) just by using the New Holland combine — a savings of $3.60 per acre!

NH T8 SmartTrax vs. JD 8335RT 2-Track System

The T8 SmartTrax tractor is fundamentally different from any two-track system. A recent trade in on a T8 Smarttrak unit at New Holland Rochester was used to demonstrate just how much different they really are and what that impact has on the operator.

One salesman, who was attempting to video the ride with his phone, drove the JD 8335RT over a block of wood. As you can see, the bounce from the tractor was severe and you can see that the track actually was airborne as it came off the piece of wood. The lack of a suspension cab (JD doesn’t offer one) didn’t help.

The T8 was driven over the same block, same speed and while the track ‘snaps’ over the piece of wood, the impact on the driver is nominal and the track doesn’t appear to come close to leaving the wood.

This video clearly demonstrates why the New Holland system provides better traction (much more even ground pressure) and a smoother ride. See us for a demo and experience the T8 SmartTrax for yourself.

NH T8 CVT vs. JD 8370R IVT

The Nebraska tests are now coming out on Tier IVb tractors with CVT transmissions.   We reviewed  the Nebraska test 2102 for a JD 8370R with an IVT transmission, DEF and CEGR engine using two turbochargers to stuff enough heated air in the engine to achieve a 16:1 compression ratio is and compared it with the NH T8.420 with CVT:

JD 8370 with IVT Neb Test | NH T8.420 with CVT Neb Test

Notice that while the horsepower at rated RPM is identical (351) the NH uses less fuel (18.44 for NH vs. 18.93 for JD), the torque rise is higher (50.7% for NH vs. 43.6% for Deere or a 16.2% advantage to NH) and the while the report says that Deere claims regeneration occurs only once every 50 hours, the tractor did regenerate in the 32 hour test period.

This test is just one of the many reasons why we believe we have the best high horsepower tractor on the market. We would enjoy speaking with anyone interested in these results, and give a demo of our tractor to get the real feel of the superiority of the product.

Deere runs with Exhaust Gas Recirculation + DEF

The Deere high horsepower tractors use CEGR and DEF technology to meet Tier IVb emission levels. Using two systems to accomplish what New Holland accomplishes with DEF technology only greatly increases complexity and cost for the owner throughout the life of the tractor as well as higher operating costs on fuel. The CEGR technology adds a second turbo charger (NH uses one, Deere uses compound (2) turbo chargers), a Diesel Oxidation Catalyst (non on New Holland tractors), a Diesel Particulate Filter (none on New Holland tractors), and an Exhaust Gas Cooler (New Holland has none) in order to cool the recirculated air and a larger Air-To-Air Intercooler than New Holland uses because the hot recirculated air has to be cooled.

The DEF equipment on the Deere tractor has similar components as New Holland’s DEF equipment. All of the Deere CEGR equipment is ‘extra’ machinery that the New Holland owner doesn’t need to buy or maintain:

One might ask why New Holland uses CEGR technology on smaller tractors if it isn’t a good idea? Fact is, CEGR has benefits in small engine applications simply because small engines use a fraction of the air that larger tractors use and typically, smaller tractors don’t have constant high engine loads typical of high horsepower tractors’ applications. The lower combustion temperatures needed for CEGR to meet emission levels occurs more naturally in the smaller tractor.

The use of dual technologies (DEF plus CEGR) in high horsepower Deere tractors presents a huge liability for the owner throughout the life of the tractor that the New Holland single technology (DEF only) doesn’t provide to the New Holland owner. Deere points out that the DEF use will be lower because of the dual technology. While this remains to be seen in real world use, we would point out that diesel currently sells for about $4.00 per gallon whereas our Open House price on DEF was $1.39 per gallon.

Nebraska tests on Deere’s Tier IVa tractors showed higher diesel use than the New Holland Tier Iva tractors and the Deere tractors didn’t meet Deere’s advertised horsepower levels OR torque rise. See Nebraska tests 1990 and 1991 attached:

Exhaust Technology: New Holland vs. John Deere

New Holland uses Selective Catalytic Reduction (SCR) technology to meet mandated emission levels for engines above 175 hp. John Deere has elected to used Cooled Exhaust Gas Regeneration (CEGR) technology. We’ve seen significant improvement in fuel economy in our tractors using SCR technology over our prior Tier III powered units and we’ve had customer reports of better fuel economy with NH tractors vs. Deere Tier IVa tractors in side-by-side field use. There are issues of rpm limits and maintenance requirements with an engine using CEGR. We wanted to bring some things to the attention of customers so that a clear understanding of this engine technology might be possible. While Deere has announced that their Tier IVb solution will include SCR technology, their announcement included information that the CEGR technology will be incorporated into the engine going forward as well – meaning that two systems will have to be maintained instead of one.

Deere Auto Exhaust Filter Cleaning Mode This is from the Deere Operator’s manual and it mentions that there may be higher idle speeds induced during regeneration and that elevated exhaust temperatures are possible. Additionally, the operator may be advised to change how the tractor should be operated. With the NH tractor, the operator is always able to operate the tractor in a normal manner without being directed by the engine controller how to do things.

E-Zoil Particulate Filter Technical Bulletin This July 2011 bulletin from a respected oil additive company is very direct. It flatly states that regeneration does not remove ash from the filter.

It also states that “All DPF’s are subject to premature plugging because of ash”. If a customer is considering purchase of a used machine – regardless of brand or type of machine – using CEGR technology, it would be wise to know how the previous owner maintained and operated the machine. As you can see in other items posted here, running the engine in certain ways that would save fuel (less than 1800 rpm) will have the effect of decreasing filter life.

Deere Exhaust Filter System Overview This information is from the Deere 8000 series Operator’s Manual. It describes the modes of operation and includes mention of disabling the system when the unit is inside for maintenance as well as a ‘Parked Regeneration’. The NH engines with SCR technology can be operated normally without intervention by the operator at all times.

Deere Operating The Engine This page from the Deere Operator’s Manual (the yellow highlight is added for emphasis) clearly indicates how incorrect operation (letting an engine idle more than 5 minutes) “promotes rapid accumulation of engine sludge and fuel buildup in the exhaust system”. The New Holland SCR-equipped engines have no such operating restrictions. Note that in the paragraph following the yellow highlight there is mention of a restriction on operating the engine below 1800 rpm under heavy draft load. The New Holland Ground Speed Management, which is software that automatically selects the right RPM and gear for peak fuel efficiency, has the engine running at 1600-1650 rpm under heavy loads. We can demonstrate that fuel use for a given ground speed at 1800 rpm as opposed to 1600 rpm will vary by as much as 1/3 (less fuel efficient at 1800 rpm where the CEGR engine must be run) in some draft conditions.

Deere Parked Exhaust Filter Cleaning This information is also from the Deere Operator’s Manual. Notice that an operator may be forced to park the tractor in order to comply with a need to do a parked regeneration that may last beyond 40 minutes. While this regeneration is going on, fuel is being used and no work is being done and the operator is non-productive. The New Holland SCR-equipped machines have no parked regeneration or any other restriction that would cause the operator to have to cease use of the machine.

Wikipedia Info This copy is from the online Wikipedia site and it refers to some pertinent regeneration issues such as Thermal Runaway and failed regenerations. The entire article – which we suggest one should read – describes much about the DPF system. It is available online at http://en.wikipedia.org/wiki/Diesel_particulate_filter.

We have customers with experience with CEGR and SCR equipped engines and we’d be happy to provide information from their experiences in real-life use of the technologies on the farm!
