That giant bird is lifting things from one place to another over there!

Take my seeds and oven bake, It takes guts to face me. Puree my pulp for sweetness sake, By winter, I leave no trace.

I am a heavy burden that can break your back, Yet drivers need me to stay on the right track. Used in court in a lady's heavy hand, I determine the price of things from the land. There are two of you in the front to aid, Last clue is phonetic again, let it sink, just wait.

I wear a crown only in waiting, My father may rule the land. Someday I may lead the kingdom, But today I simply stand. Who am I?

Though I remain behind, the pain does not.
