The new Cat 320F L is built for those who need strong, reliable performance at a low cost per hour. The machine features an efficient C4.4 ACERT engine that’s light on fuel. It also has a proven hydraulic system that will help you take on a variety of tasks. Unlike other brands in its size class, the machine comes equipped with more unique attributes: Robust structures, strong and stable undercarriage, a quiet and comfortable roll-over protective structure (ROPS) cab, and easy-to-reach service points are just a few. Bottom line: If you are looking for a reliable, durable, low-cost-per-hour excavator to get your work done – backed by unmatched support from a brand you can trust – look no further than the 320F L. It simply makes a great deal of business sense.
