Features At A Glance

Get to work with balanced weight and power in the Cat C7.1 engine.
Increase your fuel economy up to 5% with the standard ECO mode.
The powershift transmission works hard with machine balance to ensure drawbar power to the ground.
Power train components are specifically made to be rebuilt.
Stable Blade option senses blade bouncebefore you to reducemanual throttle use and site rework. When machine bounce is detected, the system automatically reduces ground speed eliminating bouncing to ensure a better grade finish.
Product Link™ provides location, machine hours, fuel usage,productivity, idle time, diagnostic codes, and other machine dataon demand through the VisionLink® online interface, which helps you improve job site efficiency with lower operating costs.
Update machine software with Remote Services without taking the machine out of service.
Aftertreatment systems apply proven technologies to strategically meet your high expectations for productivity,reliability, and service life (India CEV Stage V emission standards only).

Choose your comfort level in the cab with standard, comfort plus, and premium plus options.
