If you don't need to grade complex 3D profiles, 2D laser-based systems promise a rapid return. "When grade control systems for box blades and other landscaping tools are implemented, it eliminates the 'guessing' factor in terms of where finished grade is. [This increases] the efficiency and productivity of the skilled and unskilled operator, machine and process," says Baker.

"As these systems put the grade information on the machine with the operator, the time and cost of a grade checker is greatly reduced," he adds. "With the time, material and man-hour savings, it is conceivable to cover the costs of a new system on the first job."

Swapping between equipment
Unlike a production-based finishing tool such as a motor grader, the ability to move grade control systems around is important with attachments to maximize utilization. "For towed implements, quick and easy attachment to the tractor is a major consideration for cabling and hydraulic fittings," says Calvird. "Compact panel and sensor designs are needed to make moving from machine to machine simple."

According to Highfill, the Topcon GPS system can be easily swapped between different grading tools, so it is always on the proper tool for the given application. And once the system has been purchased for your production machines, it doesn't require much additional investment to be adapted to attachments.

"You have the versatility of swapping the control box, antenna and receiver. It is very simple," he says. "You can take a system off a dozer or a motor grader and put it on the box blade."
