The primary function of hydraulic fluid in earthmoving machinery is to transmit power and control the movement of the machine's parts. Hydraulic systems utilize the incompressibility of fluids to transfer force from one component to another, enabling the operation of lifting arms, buckets, and other attachments. When the hydraulic fluid is pressurized, it creates a force that can be directed to move various parts of the machinery, making it essential for tasks such as digging, lifting, and pushing.

This fluid plays a crucial role in ensuring efficient operation, as it allows for precise control of movement and strength needed to perform heavy work. The hydraulics enable operators to manipulate large loads with ease compared to mechanical linkages that could be less effective for the same tasks.

While cooling the engine, lubricating components, and powering the electrical system are important functions in machinery, they are not the primary function of hydraulic fluid. The effectiveness of hydraulic systems in earthmoving equipment is why the transmission of power and control of movement through hydraulic fluid is foundational to their operation.
