Which system is primarily responsible for controlling the power of agricultural machinery?

The hydraulic system is primarily responsible for controlling the power of agricultural machinery due to its ability to efficiently transmit power at high force levels using fluid under pressure. In many agricultural machines, the hydraulic system is utilized to operate components such as lift arms, plows, and other implements, allowing precise control over their movement and position.

Hydraulics work on the principle that a small amount of force applied to a fluid can create a much larger force through the use of hydraulic cylinders and piston systems. This makes hydraulic systems particularly well-suited for agricultural applications, where lifting heavy loads and precise control are often required.

Other systems have their own roles, but they do not directly control power in the same manner. The electrical system typically provides power to various components and systems within the machinery, such as starting the engine and operating lights or electronic controls. The mechanical system refers to the physical components that convert power into motion but doesn't control that power source directly. The farming management system is primarily concerned with planning, monitoring, and analyzing all activities on the farm and does not control machine power.
