At the heart of the top three 6D Series Tractors is an electronic 4.5L PowerTech E diesel engine. It's the driving force behind every job you want to do with this tractor. Baling. Mowing. Light tillage. Pulling box blades. Loading. Whatever it is, this engine puts you in the driver's seat. You can count on constant power over a wide range of rpms without sacrificing fuel efficiency.

The 6100D has the proven efficiency of the field-proven PowerTech engine with a rotary fuel injection pump. The three other models step it up a notch with the PowerTech E engine with the high-pressure common rail (HPCR) injection system for increased engine performance at low rpms. All models also deliver up to 25 percent torque rise. You'll get your work done quickly and efficiently - more quietly, too, thanks to the multiple-rated speeds. High-pressure common rail fuel (HPCR) injection system is standard on the 6115D, 6130D and 6140D models. With the high-pressure common rail fuel injection system, you'll get increased engine performance at low rpms for excellent fuel efficiency.
