The Level-Best Grading Box, made by ATI, is designed to provide finish-grade elevations to within 0.125- to 0.250-inch of specifications, depending on the laser system used. An ATI-designed hydraulic system automatically raises or lowers the grading box in response to laser signals. The grading box is available with a 48-inch drawbar that helps dampen the tractor's vertical movement, and with an adjustable top link that allows adjusting the pitch of the box for a neater finish.
