What can occur if the grader is attempted to cut deeper than 4"?

When a grader attempts to cut deeper than 4 inches, it can lead to stalling or cause the machine to pull to one side. This happens because the grader's engine has to work significantly harder to penetrate the ground at a depth greater than its designed capability. The excessive load can overwhelm the engine, resulting in a loss of power, which can cause stalling. Additionally, if one side of the grader encounters more resistance than the other, it can create an imbalance, making the machine pull to one side, affecting both the control and operational efficiency. Thus, maintaining an appropriate cut depth is crucial for the effective and safe operation of the grader.
