Adjustment relative to the same position. When thedistance is too short, backup and start on the oppositeshoulder with the opposite blade angle adjustment. Byrepeating overlapping passes made in this manner, youcan side cast two windrows from the shoulders to thecenter line where they are combined into one. Thecenter windrow is then spread with the blade set at 0degrees. Material spill around the blade ends is spreadevenly among the slope of the crown.NOTE: When grading, the operator cannot obtaina full-visual view of a project site from the operator’sseat. For this reason, the operator should stop and climboff the grader periodically to take a visual look at thework area to determine work progress and areas thatneed attention.High Bank CutsHigh bank cuts are used to cut or trim slopes onditches, deep cuts, and high fills. The circle and bladeare positioned vertically on the side of the grader. Thetoe of the blade is angled forward of the heel.NOTE: Read the operator’s manual for the type ofgrader you are operating to receive instructions onsetting up the circle and blade for high bank-cuttingoperations.When performing high bank cuts, lean the top of thefront wheels towards the bank or slope. Move the graderinto position and set the blade on the slope (fig. 10-30).When cutting, make light cuts with the toe of the blade.Figure 10-29.—Flat-bottom ditch cut.The heel of the blade does not require many adjustments.When too much down pressure is placed on the blade,you will lift the side off the grader or cut a gouge in theslope. After the high bank cut is performed, clean thecut material from the base of the slope, using theditching technique.Wide Side Reach (Spreading)A grader may be used in spreading piles of loosematerial. When there is space to work around the pile,Figure 10-30.-High bank cut.10-13
