In the transition to Tier 3 emissions compliance, New Holland replaced a 5.9-liter engine in the 24-ton E215 with a 6.7-liter CNH six-cylinder developing 160 horsepower at 2,000 rpm. Lower rated engine speed should reduce noise and extend the engine’s life. Two larger-displacement pumps, pushing higher flow (58 gallons per minute), working at reduced speed (2,000 rpm, down from 2,150 rpm) also contribute to reducing noise, extending life, and improving reliability. Redesigned boom and dipper sticks are lighter, yet New Holland says they are designed for durability and increased lift capacity.
