Overview

Productive hauling begins with the operator, who sits in the new state-of-the-art cab, designed for efficiency and equipped with features that automate functions. The Next Generation 785 offers a new integrated speed coaching feature to give feedback on how to operate the truck most productively. Truck responsiveness and controllability are enhanced through multiple upgrades such as Anti-lock brake system, dynamic stability control (DSC), enhanced traction control, machine speed limiting, hill start assist with anti-rollback, and cruise control. Additionally, new Auto Hoist control reduces dumping time and unburdens the operator.
