When maintaining skinned areas on a sport field, dragging should be conducted at what speeds?

1. 5 feet

2. 10 feet

3. 15 feet

4. 20 feet

The correct answer is: 10 feet

Dragging skinned areas on a sport field at a speed of 10 feet is considered optimal for several reasons. At this speed, the dragging process effectively levels the surface and redistributes the material without overly compacting it or risking damage to the field. This speed allows for a thorough yet gentle treatment of the area, ensuring that the soil and materials can be properly blended and aerated, promoting better playing conditions. Maintaining the integrity and quality of the surface is vital for player safety and performance. Faster speeds might lead to inadequate mixing of the soil and topdressing materials, potentially causing uneven surfaces or inadequate moisture retention. On the other hand, too slow of a speed can result in unnecessary wear on equipment and prolong the maintenance process without significant benefits. Overall, dragging at this specific speed strikes a balance between efficiency and effectiveness, making it the best practice for maintaining skinned areas on a sports field.
