System Description
The EconoGrade Machine Control Systems were designed to let you achieve maximum control of
your grading system, at a very friendly price. The four congurations of the EG Series are versa-
tile and can be installed on a number of machines including box blades, box scrapers, graders,
mini-graders and skid steers. The system controls most valve packages, giving the user both LED
and a real-time LCD display so you are always in touch with the blade position. The EG Series Re-
ceiver can detect any rotating red beam laser within its 173mm (7”) capture range, and in turn indi-
cates the blade’s position to within a 2mm (5/64”) accuracy. The receiver has LED indicator lights
that give the same output as the control box LED indicators. So whether you’re standing on the eld,
or driving the machine you’ll always know where your blade needs to be. The control box allows
the user to congure the display to indicated variances from the on grade position in real time. The
receiver is able to attach to a 45mm (1 3/4”) standard pipe. The complete system requires 10 - 30vdc
to operate.
