Rated engine horsepower ratings are included for reference to competitor’s gross or engine only power ratings.  There are several ratings systems used by other manufacturers.  John Deere uses the horsepower rating standard 97/68 EC, which is widely used in Europe for various regulations.

John Deere engineering uses a precise procedure to measure engine only power levels.  The 97/68 EC standard is required in the European Union (EU) as an emission test, so there is some relation to the power a tractor has as a whole functioning unit.  However, the procedure requires only that a production engine and radiator are used on a dynamometer test. 

You can use the 97/68EC horsepower ratings in the above chart to compare to competitor claims of “engine only” power.

All 6030 Premium Series tractor engines have a working speed range of 1000 – 2300 rpm. Constant horsepower range is from 1500-2300 rpm.

Both the PowerTech E (2-valve) and PowerTech Plus (4-valve) deliver the power when you need it the most. The 2-valve PowerTech E boosts a 5% power bulge at 2100 rpms with 33% torque rise at 1600 rpms. The Power Tech Plus weighs in with even more. A 7% power bulge at 2100 rpms and a torque rise of 35% at 1800 rpms.

There are new performance characteristics of the 4.5L engines that assure excellent performance in most any situation.   On the PowerTech Plus engine key features such as the Variable Geometry Turbocharger (VGT) and 4-valve head provide the ability to accomplish faster torque rise and increased fuel economy.

Both PowerTech  engines reach peak torque quickly. In the charts you can see when compared with previous models, 6030 Premium Series tractors reach peak torque 35% faster.

The Power Tech Plus (4-valve) provides 14% more torque rise and faster than technology utilized on the 6020 series.  Maximum torque rise is achieved at 1800 rpm compared to the previous 1500 rpm. 

This provides:

·         Power through tough spots, faster

·         Return to target speed faster

·         More constant working speeds

·         Reduced operating costs

The Power Tech E (2-valve) engine incorporates proven technology.  Torque rise is 2.3% greater than that of the 6020 Series with maximum torque rise achieved at 1600 rpm - which is 100 rpm faster than the 6020 series.

From rated speed to peak torque the 6030 Premium Series PowerTech Plus engine drops only 500 rpm to reach peak torque, a 300 rpm increase over the 6020.  Dividing the rpm change, it shows that the 6030 Premium Series 4.5L engine will achieve peak torque at a 40% quicker rate than the models it replaces.

The operator of a 6030 Premium Series tractor will experience the increased tractor performance made with plenty of torque and overall power. Improved load starting, pulling through tough spots or transporting will be appreciated.

The comparison chart also shows that, regardless of engine selection (2-valve or 4-valve) a current 6020 Series owner will be satisfied with the 6030 Premium Series model performance.

The new features are as follows:

The PowerTech Plus (4-valve) 4.5L engine features include:

·         16-valve head (4 valves per cylinder)

·         Variable geometry turbocharger

·         High pressure common rail injection

·         Single injector control

·         Exhaust gas recirculation
 

John Deere PowerTech E (2-valve) 4.5L engine features include

·         8-valve head (2 valves per cylinder)

·         Multiple injection strategy which includes two small pre-injections prior to top dead center followed by the primary injection

·         Fixed Geometry turbocharger

·         Exhaust gas recirculation technology is NOT utilized on the Power Tech E.

A head-to-head comparison lists the four key comparative features

Controlling fuel consumption while meeting U.S. emission regulations of Tier III mandates will be a challenge for all manufacturers to address. The technological approach which John Deere has pursued with the 4-valve PowerTech Plus ™ engine is showing best-in-class performance utilizing factory observed data against the competition.  (Note: Official Nebraska Testing will occur in Spring-2007).    

When evaluating hp-hr/gal fuel consumption under 75 % load (which is the normal operating load for Utility Tractors), the Power Tech Plus (4-valve) is:

• 10.8% better than Cummins
• 11.2% better than Perkins
• 8.8% better than the 2-valve John Deere PowerTech E (2-valve)

John Deere factory observed testing has shown that most customers operating the PowerTech Plus (4-valve) engine at 75% load factor will see between 4 and 9% increase in fuel economy when compared to a 6020 Series tractor. To ensure accuracy when conducting this fuel consumption comparison, both 6020 Series and 6030 Premium Series must be in the same conditions under the same load.  When John Deere engineers make a comparison test, every effort is made to test tractors with the same load, ground speed, and environmental conditions.  Your results may vary from the 4-% increase in fuel economy and actual gains in fuel economy will depend on how the tractor is operated.

Engine basic specifications

The large oil sump provides oil capacity for long, 500 -hour change interval when John Deere PLUS-50™ oil and a John Deere oil filter are used.

There is special engine break-in oil used at the factory to assure proper seating of all components.  The oil and filter should be changed after the first 100 hours of operation.

To further reduce maintenance requirements, long life coolant/antifreeze with coolant conditioner is used as the factory fill on all 6030 Premium Series tractors.  The first required change interval is at 3 years or 3000 hours.  If John Deere Cool-Gard™ is not used as the replacement fluid; intervals are reduced to 2 years or 2000 hours.  The only item that is required on an annual basis for your cooling system is a simple test of coolant conditioner.
