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.
How is engine-only rated and maximum power determined?
 
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.
PTO power and power bulge
 
The John Deere exclusive single-injector control, electronic fuel injection system, and other key engine parts work together to sense engine load and instantly respond as needed to pull through tough spots. This reduces engine rpm fluctuation resulting in the reduced need to downshift the transmission. Fewer shifts results in fewer ground variations, providing more overall tractor productivity.
 
To match the engine power characteristics and improve economy of operation, the rated engine speed is 2300 rpm.

Torque rise comparisons
 
All 6030 Premium Series Tractor engines have a working speed range of 1000 to 2300 rpm. Constant horsepower range is from 1500 to 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-percent power bulge at 2100 rpm with 33-percent torque rise at 1600 rpm. The PowerTech Plus weighs in with even more: A 7-percent power bulge at 2100 rpm and a torque rise of 35 percent at 1800 rpm.
 
There are updated performance characteristics of the 4.5 L engines that ensure excellent performance in most any situation. On the PowerTech Plus engine, key features such as the 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 percent faster.
 
The PowerTech Plus (4-valve) provides 14 percent more torque rise, 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 PowerTech E (2-valve) engine incorporates proven technology. Torque rise is 2.3 percent 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 the 6030 Premium Series 4.5 L engine will achieve peak torque at a 40-percent-quicker rate than the models it replaces.
 
The operator of a 6030 Premium Series and 7130 Premium Tractor will experience the increased tractor performance made with plenty of torque and overall power. Improved load starting, pulling through tough spots, and transporting will be appreciated.
Reduced fuel consumption
 
There are several updated designs in all of the 6030 Premium Series and 7130 Premium Tractors that have made a favorable impact on fuel economy. These designs work together to provide a more efficient use of engine power resulting in less fuel consumption.
 
The updated features are as follows:
The PowerTech Plus (4-valve) 4.5 L engine features include:
  • Sixteen-valve head (4 valves per cylinder)
  • Variable geometry turbocharger
  • High-pressure common rail injection
  • Single injector control
  • Center injection control
  • Cooled exhaust gas recirculation
John Deere PowerTech E (2-valve) 4.5 L engine features include:
  • Eight -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 NOT utilized on the PowerTech E.

John Deere factory-observed testing has shown that most users operating the PowerTech Plus (4-valve) engine at 75 percent load factor will see between a 4 and 9 percent 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-percent increase in fuel economy and in fuel economy will depend on how the tractor is operated.
 

Additional reduction in fuel consumption can also come from the IVT™ (Infinitely Variable Transmission) on the 6330 and 6430 Premium Series Tractor. See the IVT section of this manual for more details. Engine basic specifications:

Oil and coolant drain intervals
 
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 ensure 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 and 7130 Premium 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 required on an annual basis for your cooling system is a simple test of coolant conditioner.
