Fine Grade Made Easy Concept The Level Best laser grading box utilizes lasers, machine control technology, and a digital proportional valve to dramatically increase grade accuracy. Using this technology, operators can reach grade faster and easier. The Level Best laser grading box's accuracy allows for more precise material estimates which reduces overages and saves time. How It Works The laser machine controls are easy to learn and use. As the operator grades, the system's receiver detects laser light from a rotating beacon and transmits a signal to the Level Best hydraulic controls. The proportional hydraulic valve uses the signal from the receiver and automatically lowers or raises the grader box to the required grade. Precise finish grade is attained when the on-grade light remains illuminated. The finish grade elevation is consistently level to within 1/4 or 1/8, depending on the laser system used and the deadband setting.
