This hydraulic accumulator stores pressurized fluid to dampen pressure surges and provide reserve flow in the host tractor's hydraulic system. It connects to the pressure line between the pump and the control valves, absorbing shock loads during directional changes and compensating for momentary demand spikes. A worn accumulator loses its pre-charge, causing rapid cycling of the pump and noticeable lag in implement response. This Parker-manufactured unit uses a bladder-type design that matches the original housing's seal profile, ensuring the pre-charge pressure is held correctly without leakage. On installation, verify the pre-charge pressure with a nitrogen gauge and torque the fitting to the housing specification.
