Caterpillar has added another GC-designated machine to its equipment lineup, the Cat 120 GC motor grader. The machine is engineered for a range of applications that include government and municipal work, county road maintenance and finish grading.

The GC tag represents a value-oriented design for small to medium-size contractors that don’t necessarily need all the bells and whistles of a high-spec production machine. It's a simpler machine for a variety of tasks. The owning and operating costs for the new 120 GC can be 20 percent lower than a standard Cat 120 motor grader, thanks to better fuel economy and a lower price, says Eric Kohout, product application specialist.

“The Cat C4.4 twin-turbo engine pairs nicely with the torque-converter drive transmission,” says Kohout. The transmission with torque converter eliminates the need for an inching pedal, so only throttle and brake pedals are required, which simplifies operation. “If you’re on and off of that inching pedal all day and wearing your leg out, this is an alternative where you can control the machine with just the throttle and brake,” says Kohout.

The 171-horsepower engine is matched to the standard rear-wheel drive and optional all-wheel drive, and the eco mode operation increases fuel economy up to 5 percent. The hydraulic cooling fan, with an optional reversing fan for high-debris applications, only runs when necessary to further reduce fuel consumption. The 120 GC is also Cat’s lowest-weight motor grader, some 2,000 pounds lighter than the standard 120, says Kohout.
