Case Construction Equipment introduces the 721E wheel loader, which features enhanced operator comfort, Tier 3-certified power, and improved maintainability and serviceability, including ground-line service checks. The 721E wheel loader is powered by a fully electronic 6.7-liter Tier-3 Case engine that produces 183 net hp. The machine has an operating weight of 30,644 pounds and a bucket capacity of 3.01 cubic yards. The engine allows operators to match power and fuel economy to their application by choosing between three power curves (max, standard and economy power), and four work modes (max, standard, economy and auto). In auto mode, the electronically controlled engine adjusts between power curves to move the maximum amount of material per pound of fuel. The quiet, roomy cab features tilt steering and infinitely adjustable seat and arm rests.
