Caterpillar backhoe loaders can be factory-equipped with one of two of the company's AccuGrade machine-control and guidance systems. The Site Reference system is a grade-and-depth-check system that allows the operator to excavate to predetermined coordinates. Once points are established, an in-cab display provides information on cut, slope, pitch, roll, distance to target grade and bucket position. The Laser Reference system employs a remote laser transmitter typically used to set a grade reference over an entire work area. This system provides all the functions as the Site Reference system, and allows the machine to quickly engage in different tasks as it moves from job to job on the worksite.
