Abstract
A machine is provided with a first work arm, at least one first cylinder having a first lift chamber configured for receiving pressurized fluid so as to lift the first work arm, and a first accumulator associated with the first lift chamber of the first cylinder. The machine further includes a second work arm, at least one second cylinder having a second lift chamber configured for receiving pressurized fluid so as to lift the second work arm, and a second accumulator associated with the second lift chamber of the second cylinder.
