Hi,
Can you move the tines by hand???
They should turn by hand if you try to move them...if not then they are bound up by something...
either a bearing has gone bad, something has wrapped around them, or there is something stuck in there that will not let them turn...check for a rock stuck between one of the tines and the housing around them...

Get the tines moving freely and you will be okay again...
