This cabin suspension spring buffer sits between the cab frame and the chassis, absorbing vibration transmitted from the tractor chassis to the operator station. It compresses and rebounds with the suspension spring to dampen vertical oscillations, reducing driver fatigue during field work. A worn buffer allows the cab to bottom out on large bumps, transmitting shock loads directly to the cab mounts and the operator seat base. This original AGCO component is molded to the same durometer and geometry as the factory-installed buffer, so it maintains the designed spring preload and damping curve without requiring shimming or bracket modification. On replacement, inspect the spring seat for corrosion and ensure the buffer seats fully in its pocket before tightening the retaining hardware.
