Cat® 350 Hydraulic Excavator
The Cat® 350 is known for its premier productivity, low owning and operating costs, and easy-to-use Cat technology. With a bucket capacity ofup to 3.2 m3 (4.2 yd3) and outstanding digging force and swing torque, the 350 can move tons of material for top production. The cab features large windows at the front, sides, and rear, giving excellent visibility in all directions from the operator's seat. Narrow front cab pillars allow a wider field of view to the front. The 350 will help you get tons of work done on grade and on time.

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 1,800 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.
