The Grade Mate Laser Grading System allows one operator to finish a fine grade to 50,000 square feet with accuracy to ¼ inch, all in one day, says the company. The unit is ideal for final preparation of a large site for concrete. The maneuverable machine provides even grading, thanks to the distance of the cutting blade from the tractor. Features include a machine-mounted console to monitor functions and a full-width roller that compacts sub-base materials and eliminates tire tracks and scraper bounce.
