Overview

Versatility at the Lowest Cost Per Hour

The Cat 320D3 GC is a smart choice for operations where high reliability and low
cost-per-hour performance are priority. Excellent engineering from the bucket
to the tracks and everywhere in between, the 320D3 GC gives you
dependable performance, low operating costs, and more comfort for operators.

Benefits

Low Fuel Consumption

Two power modes, Standard and Eco, deliver options for less fuel usage, and optional fuel consumption tracking in VisionLink® provides more control of fuel consumption.

Low Maintenance Costs

Maximize uptime with less extended service intervals for the hydraulic filter, 6,000 hours of hydraulic oil service, and no pilot or drain filters.

Simplicity Adds to Reliability

An integrated pilot system and a 6-cylinder mechanical engine without an Electronic Control Module (ECM) and integrated pilot system enable simpler hydraulics. Compatibility with a hammer and bucket add to the machine’s versatility.
