Getting Ready to Grade
Motorgrader System Five Operator’s Manual
4-4
Position the "L"-Bar horizontally so the Tracker will be over the
reference for the jobsite. For example, when tracking a stringline that
is offset from the edge of the road, set the end of the moldboard at the
edge of the road and slide the "L"-Bar so the Tracker is over the
stringline. When tracking a curb, keep the "L"-Bar in close to keep
the Tracker over the lip of the curb.
Raise or lower the Tracker bracket to position it at a proper height
above the grade reference. Although the Tracker can be set as close as
14 inches and as far as 55 inches from the grade reference, consider
the job application for the best set up. When tracking multiple
references, for example, elevated string on one pass then matching
grade on the next pass, consider the Tracker position so it works for
both applications without having to move the Tracker.
