325 Hydraulic Excavator
The Cat® 325 Excavator brings premium performance with simple-to-use technologies like Cat Grade with 2D, Grade Assist, Lift Assist and Payload – all standard equipment from the factory to help boost operator efficiencies. Combine these features with a compact radius design for working in tight spaces, an ergonomic cab, extended maintenance intervals that help lower your maintenance costs, and a power system that helps reduce fuel consumption and you have a low-cost-per-unit-of-production excavator that’s perfect for medium- to heavy-duty applications. An optional blade allows for fast job site cleaning and leveling, and an optional heavy counterweight helps maximize the performance of this compact radius machine.

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) or 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. *Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer). **Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.
