The 325F compact-radius excavator has a Tier 4-Final Cat C4.4 ACERT engine paired with a responsive hydraulic system. It can run on bio-diesel up to B20. It will consume up to 22 percent less diesel fuel compared with its Cat 321D Tier 3 predecessor, with no loss of swing torque and bucket and stick forces, Cat says. With a maximum lifting capacity of 27,000 pounds at 15 feet over the front at ground level, the 325F exceeds its predecessor model's capacity by 8 percent. The 325F has isochronous control that automatically manages pump and engine speed for improved fuel efficiency. Boom and stick recirculation valves reduce fuel consumption and speed up cycle times. A variable-speed fan for less energy consumption and noise, high-ambient cooling capability to work in extreme heat, and altitude capability up to 9,840 feet with no engine de-rating are also included.
