The state’s largest fleet of excavators and articulated trucks are best suited for earthmoving in the Northwest, combined with scrapers, achieves more production per hour on mass grading projects.

GPS Capabilities

For decades, equipment operators took their instructions from stakes in the ground that had to be moved and reset as the work unfolded. Grade stakes will soon be obsolete, thanks to 35 Global Positioning Satellites that send radio signals to earth.
