(50) Ride control switch (51) Ride control indicatorRide control switch (50) is mounted in the switch panel in the operator station. Ride control indicator (51) is located on the indicator panel in the operator station.When the ride control system is activated, the head end oil in lift cylinders (12) is connected to ride control accumulator (10). Ride control accumulator (10) provides a cushioning effect to the lift cylinder head end oil, allowing the lift cylinders to extend and retract slightly. The bucket can move as a balance weight against the movement of the machine.Ride control switch (50) has three positions, the OFF position, the AUTO position
