This hydraulic hose carries pressurized fluid within the combine's hydraulic system. It connects components in the circuit that actuates driven functions such as the reel, auger, or cleaning fan. A cracked or leaking hose causes a drop in system pressure, which slows or stops the driven component and can contaminate the fluid with debris. The original hose matches the length and end-fitting geometry of the assembly it replaces, so no adapters or re-routing are needed. On installation, inspect the sealing surfaces and route the hose away from any sharp edges or moving parts.
