Volvo EC140D, EC160D and EC220D excavators are up to 14-percent more fuel-efficient with Tier 4-Interim engines and offer up to 7 percent more gross horsepower. Greased and sealed track chains are standard, and a new rear access located behind the cab of the EC140D and EC160D models allow better reach to the main hydraulic components and engine. Operating modes include I-idle, F-fine, G-general or H-heavy with the machine automatically setting the appropriate engine speed for the work mode.
