When a fill is desired during back-dragging, the front of the bucket should be positioned:

When creating a fill during back-dragging, positioning the front of the bucket slightly tipped down is essential. This orientation allows for better material movement and control. By angling the bucket down, the operator can effectively scoop and pull the material towards the back of the machine while ensuring that the fill material is deposited evenly and efficiently. This technique helps prevent material from spilling out as it drags along the ground, thus maximizing the amount that is moved and minimizing waste.

Other positions, such as leveling or tipping up the bucket, may not provide the same level of engagement with the ground or could result in less effective material distribution, making the filling process less efficient. Therefore, a slight downward tilt is advantageous for achieving the desired fill when back-dragging with a TLB.
