A 2D laser-based systems offers even simpler setup and operation. Laser machine controls are typically used for these applications. "Although there are 3D systems that could be used for these applications and machines, the laser-based systems provide contractors with an economical and easy to set up and use solution for smaller machines," says Baker. "Rotating laser transmitters using hand-held receivers have been on construction jobsites since the '70s, so any possible drawbacks are understood and controlled."

The complexity of the 2D system hardware really depends on the chosen system. "Operator-controlled or 'display' systems use a machine-mounted laser receiver with red lights directing the user from above and below, and green on-grade lights directing the user as to which direction to move the blade or bucket to grade," says Baker. "These display systems are easily moved from machine to machine for a variety of applications. This is especially important for compact machines, which are used for both finish grading and general utility."

Automatic grade control systems take a little more initial setup. "Automatic blade control systems are currently more integrated than display systems and are a more challenging installation," says Baker. "The advent and implementation of EH (Electro-Hydraulics) is potentially enabling quicker and simpler installations."

Whether you chose a 3D or 2D solution, indicate lights or full automation, grade control can turn your attachment into a smarter tool. "Some of the key benefits," says Baker, "include consistently controlling materials at each level of elevation; managing costs better; reducing passes to grade and reducing/eliminating rework; and improving cost and time savings, which directly impact the bottom line."
