After back-dragging the entire area in one direction, how should the operator proceed?

After completing back-dragging in one direction, it is important for the operator to change direction to achieve a more uniform result and ensure any remaining material is effectively smoothed out. By back-dragging in the opposite direction, you'll be able to address any inconsistencies or unevenness left behind from the first pass. This method allows for better material distribution and surface preparation, resulting in a more level and finished area.

The opposite direction strategy helps in thoroughly breaking down any clumps or high spots that may have been missed initially, thus improving the overall quality of the work. This technique can also aid in avoiding the creation of ruts or ridges that can occur if the operator continues to work in the same direction. Overall, alternating the direction of back-dragging contributes to achieving a better and more effective surface finish.
