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.
Reduced radius is ideal for work in space-restricted areas.
Site prep and finishing work are quick and easy with a wide range of Cat work tools.
Utility work is fast and flawless with a Cat bucket and compactor.
A coupler lets you swap between attachments in seconds without leaving the cab.

The roll-over protective structure (ROPS) certified cab is quiet and comfortable.
Automatic climate control helps maintain consistent cab temperature.
Joystick consoles and armrests are adjustable.
Seats are adjustable and feature air suspension and heated and cooled options.
The LCD monitor is easy to navigate and programmable in 42 languages.
Booms and sticks are built with baffle plates for enhanced service life.
Box-section structures with multi-plate fabrications, castings, and forgings are used in high-stress areas.
Greased track link between pins and bushings increases undercarriage life and reduces noise.
Many routine service and maintenance points can be accessed from ground level reducing the time taken to check and service your machine.
Service doors are designed to prevent debris entry and to make access to fluid taps and filters easy.
The cooling package is designed to prevent plugging and has wide clearance to help make blowing off debris easy.
The side-view camera is offered to enhance visibility on the boom side of the machine to help make operators more effective and efficient.*
*Regulation requirement for Europe only.
Cat Connect technology improves job site efficiency.
Product Link™ system connects owners to their equipment, providing access to machine data such as location, hours, fuel consumption, idle time, events, and diagnostic codes.
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.
