The 2-valve PowerTech E boosts a 5-percent power bulge at 2100 rpm with 33-percent torque rise at 1600 rpm. Constant horsepower range is from 1500 to 2300 rpm.īoth the PowerTech E (2-valve) and PowerTech Plus (4-valve) deliver the power when you need it the most. PowerTech Plus (4-valve) performance curveĪll 6030 Premium Series Tractor engines have a working speed range of 1000 to 2300 rpm. ![]() To match the engine power characteristics and improve economy of operation, the rated engine speed is 2300 rpm. Fewer shifts results in fewer ground variations, providing more overall tractor productivity. This reduces engine rpm fluctuation resulting in the reduced need to downshift the transmission. 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. You can use the 97/68EC horsepower ratings in the above chart to compare to competitor claims of engine-only power. 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. John Deere engineering uses a precise procedure to measure engine-only power levels. How is engine-only rated and maximum power determined? John Deere uses the horsepower rating standard 97/68 EC, which is widely used in Europe for various regulations. There are several ratings systems used by other manufacturers. Rated engine horsepower ratings are included for reference to competitor's gross or engine-only power ratings. *Note: These engine horsepowers are for 30 Series Premium Tractors with serial numbers starting at 634684 and higher. Rated engine hp 2300 rpm 97/68/EC standard* These air-to-air after-cooled engines deliver constant power over a wide range of rpm with a power bulge above rated power and excellent torque characteristics.
