What usually occurs between the bucket and the ground during operation?

Friction typically occurs between the bucket and the ground during operation of a tractor-loader-backhoe. When the bucket makes contact with the ground, the resistance to motion, or friction, plays a significant role in the handling and maneuverability of the machine. This friction is crucial for various tasks, such as scooping, digging, or moving material, as it affects how the bucket interacts with different surfaces.

Understanding friction's impact on operations helps operators manage their equipment better. For example, excessive friction can lead to wear and tear on the bucket and tires and can also affect the machine's efficiency. Therefore, recognizing the role of friction in this context is important for effective and safe heavy equipment operation.
