Overview

Premium Performance with Simple-To-Use Technologies

The Cat® 325 Excavator delivers powerful performance with easy-to-use technology such as Cat Grade with 2D, Grade Assist, Lift Assist, and Payload to help operators work quickly and accurately. Its compact radius design fits tight spaces, while the optional blade speeds up cleanup and leveling. With a fuel-efficient power system, extended service intervals, and an optional heavy counterweight for additional lift, the 325 is built to help reduce your cost per unit and excel in medium to heavy-duty jobs.

Benefits

Low Fuel Consumption

The machine’s electro-hydraulic pump and main control valve are designed to work together for optimal power and efficiency. Smart Mode automatically adjusts engine power to match hydraulic demands. And with the Auto Reversing E-fan system, your cooling system stays cleaner longer.


High Performance

Boost your productivity with built-in technology that comes standard. An optional heavy counterweight enhances lifting capability, while the optional blade helps make backfilling easy and helps keep the machine stable when working on slopes.

Low Maintenance Costs

Long-lasting fuel, hydraulic oil, and air filters, plus no pilot or case drain filters to replace, reduce the overall filter changes throughout the life of the machine. Daily checks are also safer and easier too thanks to a ground-level engine oil check that keeps operators firmly on the ground.
