Your long-term success is our goal here at Cat, so we’ve developed our 772 to be more productive and economical for our customers for years to come. Equipped with productive transmission controls, the 772 is built for heavy-duty, off-road applications and delivers quick haul cycles with automotive-quality shifting and comfort. The 772 is also built with a Cat C18 diesel engine and with our fuel saving strategies, you can adjust engine power to meet your specific needs. Ideal pass match options for the 772 are the Cat 986K or the 988K Wheel Loader and the 390F L Hydraulic Excavator. When you consider its fuel efficiency and performance, the 772 is the right Off-Highway Truck for all generations.
