Laser guided land leveling uses tractors, grading implements, a laser transmitter, laser sensor, and electronic/hydraulic control system to precisely level land for terracing, pond construction, drainage, and construction sites. The laser transmitter projects a 360-degree laser beam at the desired slope. Sensors on equipment receive the laser signal and controls hydraulics to automatically dig to the correct depth with less passes and time, reducing labor and errors compared to traditional methods. While the technology has a high initial cost, it saves substantial time and money by requiring less dirt movement, labor, and finishing passes.
