: Shows how fluid is filtered and routed back to the reservoir after completing its work cycle. Reading the Diagram Symbols : Shows how fluid is filtered and routed
, which states that pressure applied to a confined fluid is transmitted equally in all directions. By translating this principle into a physical layout of hoses, valves, and actuators, John Deere creates machines capable of immense power with surgical precision. Vector Solutions 1. Structural Components and Flow Logic
On the 3020, the closed-center system uses 5 main hoses: pump-to-brake valve, brake valve-to-rockshaft, rockshaft return, steering priority valve lines, and cooler return. The diagram clearly separates pressure (3/8" or 1/2") from return lines (larger diameter).
