Answer:
My days are numbered.
There's not a kingdom on the earth I haven't traveled over and over and though I know not whence my birth yet when I come you know my roar. I through the town do take my flight and through the fields and meadows green and whether it be day or night I neither am nor can be seen.
I help engines spin and pants stay up. What am I?
I row quickly with four oars but never comes out from under my own roof.
I must be broken before you can use me.
