Blade Control Settings

Allows the operator to specify which part of the soil profile under the blade has priority in determining blade position.

Classic: This position uses the design elevation as the target elevation under the center of the blade, and the cross-slope is determined by the design elevations under the left and right points of the blade. With Classic, it is easy to over-dig when driving down the midline of ditches, or to clip the top o a bank when straddling the ridge.
Average: This position looks at the design surface under the blade and goes for the overall trend. This is great for taking any full-field design and giving you basically that. It’s not so good for abruptly changing slopes, however.
Average, on top: This position is one step up from the trend method, literally. It determines the slope in the same way as the ‘Average’ method, but it always avoids overcutting.
Snap fit: This position attempts to find the best blade position, without overcutting. If you are going over a break line, you will see the blade snap from one position to the other as you traverse the break line. What it means, though, is that you will be cutting and filling most eciently, minimizing the number of passes and risk of rework. This option has been tailored for abruptly changing slopes.
Single point: This position is what everyone seems to want − Control-by-point. In this configuration, you pick a position on the blade represented by the red arrow. That point on the blade will be at the design elevation and cross slope even if it cuts below the design elsewhere. This is great for digging features like V-ditches
