This rake tube is the structural and hydraulic link that connects the rotor housing to the folding frame on the parent rake. It carries the drive line and fluid passages that power the tine arms. A bent or cracked tube causes misalignment of the rotor, leading to uneven windrow formation and increased vibration in the driveline. The original tube is formed to match the specific bend radius and mounting geometry of the assembly, so no shimming or bracket modification is needed during replacement.
