BLADE PRO® MOTOR GRADER CONTROL SYSTEM OPERATION DESCRIPTION.
Operator Interface Box. Puts all control
functions within easy reach of the Operator. One
Mode Switch is required to select operating
Mode switch (1) position and operating
Selected operating mode is shown in two
display windows. The left window is for the130G Grader's left side and the right window is for the
130G Grader's right side. Left and right Increase/Decrease switches (2) and (3) adjust for elevation
and slope values. Change blade slope direction, using bottom center Slope Switch (4). Set Tracer®
Sonic Grade Controller to a reference surface by pressing RESET button (5) for side controlled by
the Tracer® Sonic Grade Controller. Two remote switches, located on the left and right manual
control levers, provide control of automatic or manual operation for the left and right sides.
When desired cross-slope is entered into the Operator Interface Box, the Remote Interface Box
reads Mainfall Slope Sensor, Blade Slope Sensors, and Circle Rotation Sensor, and calculates cross-
slope. Calculated cross-slope is compared to the desired cross-slope. If an error is determined, LED
Grade Indicator displays type of correction (i.e., fine, medium, or coarse) and direction (raise or
lower) required to reach desired cross-slope. With Blade Pro® Motor Grader Control System in
automatic operation, the displayed correction is sent to hydraulic valves to reposition the blade to
desired slope. This operating speed provides very fast, smooth response to changing grade
