About the Cat 311F L RR Hydraulic Excavator

If you want a machine with the power to match your jobs but owning and operating costs to fit your business, then the Cat® 311F L RR excavator is your answer. Its reduced radius will get you into some pretty tight spots, and its reasonable price and miserly fuel burn will help you operate on a tight budget.

Features

Fuel Efficiency

The C3.4B U.S. EPA Tier 4 Final/EU Stage IV engine burns up to 14% less fuel than the model it replaces, the 311D.
The engine is equipped to run on up to B20 biodiesel fuel.
Two power modes, high power and eco mode, help operators manage fuel consumption.
Auto engine idle shutdown saves fuel, reduces emissions, and extends service intervals.
