How many functions are controlled by the main backhoe control valves, excluding the stabilizers?

The main backhoe control valves are integral to the operation of the backhoe's digging and loading functions. Typically, these valves control multiple functions related to the backhoe arm and bucket, excluding the stabilizers. A standard setup usually consists of four key functions that the main control valves manage: the raising and lowering of the boom, the extension and retraction of the dipper (also known as the stick), and the opening and closing of the bucket.

By understanding that each of these functions is distinctly controlled by the valves, it becomes clear that the total count of functions controlled by the main backhoe control valves is four. This setup allows the operator to effectively maneuver the backhoe to complete various tasks on a worksite, from digging to loading materials.
