Cat Small Excavators 311F L RR
Product Feature
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.
Versatility
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.
Durability
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.
Maintenance
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.
Safety
The side-view camera is offered to enhance visibility on the boom side of the machine to help make operators more effective and efficient.*
