Grading a Road Using a Stringline

To accomplish this, the Tracker will need to be repositioned so the
sound waves will not pick up the window at the end of the blade.
Set the blade on a smooth, previously graded pass so that the cutting
edge is just touching the ground.
Figure 5-40.
Slide the "L"-bar out, and rotate it forward to a position where the
Tracker will not "pick up" the windrow. Be sure to swivel the Tracker
bracket so the Tracker is plumb. The Tracker may end up only 18
inches or so off the ground, which is OK for this application.
