Key Specs
The Cat® 320 GC excavator balances productivity with easy-to-use technology features, a new comfortable cab, reduced fuel consumption by up to 20%, and longer maintenance intervals reducing maintenance costs by up to 20% to bring you a durable, low-cost-per-hour excavator for light- to medium-duty applications.
A precise combination of lower engine speed and a large hydraulic pump delivers top performance while burning less fuel.
An advanced electro-hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for precise digging requirements.
With extended and more synchronized maintenance intervals, you get more done at a lower cost compared to the previous model.
