This hydraulic hose assembly carries pressurized oil between components in the combine's hydraulic system. It connects the pump output to the valve bank or actuator circuit that controls functions such as reel lift, header tilt, or auger swing. A rupture or internal delamination in this hose causes a sudden loss of pressure to the affected circuit, resulting in sluggish or failed implement movement. As an original-manufacturer part, the hose is built with the correct end-fitting crimp profile and bend radius to match the routing path on the host machine, avoiding kinks that restrict flow. When replacing, ensure the hose is routed without contact with sharp edges or hot surfaces, and torque the fittings to the specification for the port size.
