Benefits

Maximum Durability

Ensure productivity in the toughest jobs with a 1.20 m³/1.57 yd³ wide severe-duty bucket, reinforced structures and front parts, and a robust undercarriage and carbody.

Up to 10% Lower Fuel Consumption*

The latest Electro-Hydraulic (EH) system, Eco mode, and optional fuel consumption tracking in VisionLink® provide more control to enable optimized fuel consumption.

* Compared to 323D3 model prior to Annual Product Update 2021. Productivity, fuel, and CO2 emissions
vary by application. Estimated average fuel consumption improvements are based on tests or
Product Link™ data where available. Productivity improvements are based on test data.

Up to 15% Reduced Maintenance Costs**

Maximize uptime and extended service intervals, thanks to advanced hydraulic oil filter design and no pilot and case drain filters. A two-stage fuel filter and anti-rust fuel tank help protect the engine against low-quality fuel.
