This hydraulic accumulator stores pressurized gas to dampen pressure surges and maintain system response in the host tractor’s hydraulic circuit. It sits in the hydraulic system, acting as a buffer between the pump and the control valves to absorb shock loads and reduce cycling of the pump. A loss of gas charge results in sluggish implement response and rapid pressure fluctuations. The accumulator is charged to the original gas pressure specification; if it fails to hold pressure, the diaphragm or seal has ruptured and the unit must be replaced. On installation, ensure the accumulator is pre-charged to the correct pressure before connecting to the hydraulic line.
