Caterpillar 311 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. The 311F engine burns up to 14% less fuel than the model it replaces, the 311D, and is equipped to run on up to B20 biodiesel fuel. With proper undercarriage maintenance and parts, this earthmoving machine can outlast the competition. Be sure to always use high quality replacement undercarriage parts when needed to keep your CAT 311 small excavator working for you.
