Command for dozing enables remote, line-of-sight operation using a portable console, which allows the equipment operator to stay out of hazardous areas, such as under highwalls, near slides or pushing to underground feeders in stockpiles. Command for dozing differs from aftermarket add-on systems, because it is fully integrated with the Caterpillar designed components, systems and electronic control modules (ECM) used on the D10T and D11T. Integration reduces complexity and cost and enables the system to deliver higher performance, better reliability, longer life and enhanced safety. The system also allows using Autocarry and Auto Blade Assist for high productivity.

Command for Dozing is the first globally available commercial product in the Command capability set of Cat MineStar System, the comprehensive and fully integrated mine and mobile equipment management system from Caterpillar.

Command for dozing has the ability to use avoidance zones set up in Terrain, another Cat MineStar System capability set. A tractor equipped with Terrain uses GNSS to create three dimensional electronic fences around fixed objects and hazardous work zones. The boundaries are then communicated to Command for dozing to warn the operator and, if necessary, to stop the machine before it enters an avoidance zone.

Command for dozing features a console from which the operator can perform virtually all machine functions—including engine startup, acceleration, deceleration and shutdown; shifting, steering, directional control and braking; blade and ripper control; and auxiliary functions such as lights and horn. Critical information normally displayed in the cab via gauges and other displays is replicated on the operator console. The operator console weighs approximately 8.5 lbs (3.85 kg) and is fitted with a shoulder harness for convenience and portability. It is available as a 900 MHz unit with an operating range of up to 2,625 ft (800 m) and as a 2.4 GHz unit with an operating range of up to 1,600 feet (500 m) depending on environmental conditions.

Caterpillar will introduce the next generation of Command for dozing in late 2011. That version of the remote control system will deliver audio and video feeds to the operator, who will work from a cab-like environment in a remote location.
