Figure 10-15.-Wheel lean on a ditch slope.the wheels in the direction of the flow of material (theheel of the blade). For example, as shown in figure10-14, viewed from the operator’s seat, the toe of theblade is extended to the right of the grader side castingthe material to the left. The material cut at the toe of theblade causes a pulling force exerted on the front end ofthe grader, wanting to pull the grader to the right. Byleaning the top of the wheels to the left (heel) counteractsthis pulling force.When grading a ditch foreslope, as shown in figure10-15, lean the top of the wheels enough to keep themin a vertical working position. This will leantechnique will do the following: (1) keep the grader fromdrifting down the bottom of the foreslope and (2) keepthe grader wheels from climbing the walls of thebackslope.On high bank-cutting operations, lean the top of thewheels toward the bank, as shown in figure 10-16. Theblade engaged in the bank cut causes a pushing force,wanting to push the grader away from the bank. Thewheel lean counteracts the force and helps keep theblade properly positioned for bank cutting.Turning AroundWhen jobs are confined to short stretches or narrowwidths, rotating the blade from forward to reversegrading position requires a circle reverse movement ofonly about 70 degrees (fig. 10-17). When reverseblading, the cut pass is normally made in reverse, whilethe side casting of the windrow pass is made on theforward trip, saving valuable time and speed inFigure 10-16.—Wheel lean on high bank-cutting operations.Figure 10-17.-Changing the blade from forward to reverse.10-7
