It is upsetting that you have experienced this failure.
The height control arm rides beside a gate. The know on top pushes a cable and in turn pushes a barrel down to disengage from the gate. My concern is that something has happened to the gate or to the height control arm. At this I would recommend that you take the mower to your local authorized WeedEater service center for inspection and repair.
Have had same problem, System seems poorly, or possibly over designed.
