A backhoe's setup requires that which of the following conditions be met?

The requirement that the entire machine must be positioned correctly is crucial for the safe and efficient operation of a backhoe. Proper positioning ensures that the machine has stability, which is essential for performing various tasks like digging, lifting, and moving materials. If a backhoe is not set up correctly, it may lead to tipping, which can cause accidents, potential injury to the operator, and damage to the machine and surrounding property.

Additionally, a correctly positioned backhoe allows for better operation and maneuvering, ensuring that the various components, such as the excavator arm and bucket, function as intended without unnecessary strain. Proper alignment with the work area also increases productivity, reduces wear on the machine, and prevents damage to the site.

In contrast, setting up a machine without leveling, being able to easily shift the machine, or ignoring ground conditions could lead to instability or inefficient operation, increasing risks rather than minimizing them. Thus, ensuring that the entire machine is positioned correctly stands as the fundamental requirement for safe backhoe operation.
