operations by eliminating frequent turning around of thegrader.NOTE: Reverse grading is only for operators whohave developed superb skills in grader operations.For reverse blading, if the scarifier unit is locatedjust in front of the blade (behind the front axle), removeall of the scarifier teeth and fully retract the scarifier unit.This allows a clear area when changing the direction ofthe blade. When reverse blading, set the blade so the toeis just outside of the rear tires, and the heel side castsoutside the front tire on the opposite side.NOTE: Store scarifier teeth in collateral equipageor in a location so they will not be lost. The operator isresponsible for all of the scarifier teeth assigned to thegrader. When you are grading on a project where the passesare less than 1,000 feet, it is more efficient to grade inrecerse or vack the grader the entire distance to thestarting point than it is to turn around and continue workfrom the far end, as shown in figure 10-18. When you are grading on a projuct where the passesare 1,000 feet or more, it is then more efficient to turnthe grader around and start blading from the far end backto the starting point, as shown in figure 10-19. The combined maneuvering advantages of theleaning front wheels and the rear tandem drive are a bigFigure 10-18.-Elinimate unproductive turning around.Figure 10-19.-Turning around.10-8
