When back-dragging with the loader, which control position yields the best results?

Using the float position during back-dragging with a loader provides the best results because it allows the loader's bucket to follow the contour of the ground more effectively. In this position, the hydraulic pressure is released, enabling the bucket to rest freely on the surface without applying additional downward force. This flexibility is crucial when smoothing or spreading materials, as it prevents over-compression of the substrate and helps achieve an even finish.

In contrast, other positions restrict the bucket's ability to conform to the ground. For instance, the neutral position does not engage the bucket, making it ineffective for back-dragging tasks. The down position applies constant downward pressure, which can lead to digging into the surface rather than leveling it. The forward position is typically used for pushing rather than dragging, and it would not facilitate the necessary adjustment to ground contours that the float position allows. Thus, utilizing the float position optimizes performance and enhances the quality of the work.
