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.

Enhance jobsite safety. Add a swing alarm to alert people when you're rotating from trench to stockpile and back again.

*The system may not detect personnel in certain circumstances, such as fast swing speeds, people lying down or crouching, or when cameras are impaired by low light conditions (dusk, dawn, overcast), inclement weather (snow, rain, fog), or other similar conditions. For limitations of use, refer to the operation and maintenance manual.

Attachments

Tackle your jobs with a complete Cat® solution. Cat attachments are not just accessories – they are essential tools that define what your machine can do. When you pair a Cat excavator with Cat attachments, you unlock a fully integrated system built for performance, durability, and efficiency. Whether you are clearing land, breaking concrete, or compacting soil, the right attachment transforms your excavator into a powerful, multi-purpose tool ready for any challenge. Depending on your project or application, you could benefit from excavator attachments such as:Buckets: Handle everything from digging and grading to cleanup and debris removal with your excavator. Caterpillar® offers general duty, heavy duty, extreme duty, and severe duty buckets, as well as specialized designs for ditch cleaning, rock, and finishing work. Reinforced edges and wear-resistant materials ensure long-lasting performance in tough conditions.

Couplers (HEX): Cat® couplers for excavators enable fast, secure attachment changes, without the need to leave the cab. From Pin Grabbers to hydraulic quick connect options, couplers help reduce downtime, boost jobsite efficiency and promote versatility by allowing multiple machines to share a common attachment inventory.
Hammers: Break concrete, rock, and steel with up to 1,000 blows per minute. Built for high-production demolition, quarrying, and construction, they offer powerful impact energy and consistent performance. Their durability and low-maintenance design make them essential for demanding breaking applications.
Demolition and Sorting Grapples: Tackle larger debris or precisely sort materials into piles. These grapples are engineered for accuracy in demolition and material sorting, handling concrete, rebar, wood, and mixed debris. High clamping force and agile movement make them ideal for primary and secondary demolition and recycling operations.
Pulverizers: Built to crush concrete and separate rebar during demolition and recycling. With high crushing force and fast cycle times, pulverizers efficiently reduce material for easier handling. Primary models feature 360° bidirectional rotation and tackle structure teardown, while secondary models have a fixed jaw design and process debris after demolition.
Compactors (Vibratory Plate): Compact soil, sand, gravel and asphalt quickly and efficiently to create a stable foundation. Vibratory plate compactors deliver high-impact force and even coverage, reducing air pockets and improving surface integrity for trenching, roadwork, and patching.
Rotary Cutters: Get accurate, precise work with less noise and vibration. Cat® Rotary Cutters deliver high torque and precision for a range of applications: demolition, grinding, profiling, trenching, tunneling, and quarrying. Specifically designed for excavator-mounted use to handle heavy-duty materials like concrete, rock, and dense brush with ease.
Tiltrotators: Tiltrotators provide 360° rotation and 40° left/right tilt functionality, allowing attachments to move with unmatched precision and flexibility. This flexibility transforms your machine into a multi-functional tool capable of working from virtually any angle without repositioning. Ideal for grading, trenching, and complex excavation work, they deliver multi-angle control for tight and confined spaces.

Cat® attachments are engineered to maximize your excavator’s productivity, helping you get more work done with greater efficiency and confidence. Choosing the right attachment is not just about compatibility, it is about unlocking your machine’s full potential while avoiding equipment damage or safety risks.
