This hydraulic reservoir stores and supplies fluid to the tractor's hydraulic system, maintaining a consistent volume for the pump inlet. It sits in the return circuit between the actuators and the pump suction line, allowing entrained air to separate from the oil before recirculation. A cracked or leaking tank introduces air into the circuit, causing spongy implement response and potential pump cavitation. Manufactured by AGCO, this component matches the original mounting geometry and port locations, so no adapter hoses or brackets are required for installation. Replace the sealing gasket on reinstall and torque the mounting bolts to specification.
