2D Grade Control

The Trimble® 2D Grade Control System for Excavators is a highly flexible laser-based system designed for excavation, trenching, grading and profile work. The Trimble 2D is ideal for earthmoving, site preparation and general contractors looking for a flexible, economical, and easy-to-use grade control system to improve their productivity and profitability.

The 2D Grade Control System uses Trimble AS450 Angle Sensor, AS460 Angle Sensor, and LC450 Laser Catcher that measure the relationship between the body, boom, stick and bucket to determine where the cutting edge is and should be, directing the operator to the desired depth and slope. You know exactly where the bucket is at all times-with no guesswork. The system also offers the Trimble CB450 Control Box to give you a powerful range of features specifically designed for unobstructed vision and in-cab excavator control.

Using the Trimble 2D system gives you a system that indicates depth and slope, or a combination of both. You can control and carry out desired depth or slope without a grade checker or laborer in the ditch. This capability significantly reduces the costs and downtime associated with staking or in the ditch grade checking, and also increases site safety by eliminating the need for a person to be present near the operating excavator.


The 2D system can improve your excavator operations on projects such as:

     • Excavating basements, foundations and footers
     • Flat bottom and simple slope trenching
     • Flat and simple slope grading and embankments
     • Profile excavation and canals or batters
