The Cat® 325 Excavator delivers powerful performance with intuitive technology to help operators work faster and more accurately. Perfect for utilities, roadwork, and urban sites, its compact radius design fits tight spaces while a fuel-efficient power system and extended service intervals help lower operating costs.
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.
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.
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 safer and easy too, thanks to a ground-level engine oil check that keeps operators firmly on the ground.
The 325 emits lower CO2 emissions compared to the previous 325F.

| Note (1) | Net power advertised is the power available at the flywheel when the engine is equipped with fan, air intake system, exhaust system, and alternator with engine speed at 2,200 rpm. Advertised power is tested per the specified standard in effect at the time of manufacture. |
| Note (2) | ¹Cat® diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) and are compatible* with ULSD blended with the following lower-carbon intensity fuels** up to: 20% biodiesel FAME (fatty acid methyl ester)*** or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations”(SEBU6250) for details. *While Caterpillar engines are compatible with these alternative fuels, some regions may not allow their use. **Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels. ***Engines with no aftertreatment devices are compatible with higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer). |

| Air Conditioning | The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a or R1234yf. See the label or instruction manual for identification of the gas. If equipped with R134a (Global Warming Potential = 1430), the system contains 0.8 kg (1.8 lb) of refrigerant which has a CO2 equivalent of 1.144 metric tonnes (1.261 tons). If equipped with R1234yf (Global Warming Potential = 0.501), the system contains 0.75 kg (1.7 lb) of refrigerant which has a CO2 equivalent of 0.001 metric tonnes (0.001 tons). |
