Using the loader in the float position aids in:

Using the loader in the float position is particularly beneficial for ensuring a smooth finish during back-dragging. When a loader operates in the float position, the bucket is allowed to follow the contours of the ground without applying downward pressure. This means that as the loader moves backward and the bucket skims across the surface, it can level out the material effectively, resulting in an even finish.

This technique is commonly used when grading or leveling surfaces, as it prevents the formation of ridges or uneven spots that can occur if the loader is actively pushing down with the bucket. The float position essentially permits the bucket to glide over irregularities in the terrain, which is crucial for achieving a precise and aesthetically pleasing surface.

The other choices do not align with the primary function of using float mode in relation to back-dragging. While reducing the need for adjustments, increasing weight, and stabilizing during operations are important factors in overall loader operation, they do not directly relate to the smooth finish achieved through the use of the float position.
