To achieve the most polished results in back-dragging, what angle should be used for the second pass?

For achieving the most polished results in back-dragging with a tractor-loader-backhoe, the second pass angle should typically fall within the range of 60 to 90 degrees. This angle allows the operator to make effective use of the loader’s bucket to achieve a smoother, more even finish.

When back-dragging, the initial pass can set the foundation, but it is through the second pass at this optimal angle that the operator can fine-tune the surface. This range strikes a balance between effectively smoothing out the material while still maintaining the necessary control over the loader's movements. At this angle, there's enough engagement with the material to achieve the desired effect without risking excessive drag or disturbance to the surface that may occur with steeper angles.

Using angles outside of this range may not provide the same level of control and finish quality. For instance, angles that are too steep could lead to an uneven surface, while those that are too shallow might not adequately engage with the material, resulting in less efficient back-dragging. Thus, adhering to a 60 to 90 degree angle allows the operator to maximize the effectiveness of the equipment for polishing the surface.
