For you city folks,
you need a tractor to make this thing work.
Lay on the ground - face down.
Then let the tractor driver drive over you.
It will not only stop the itching in your back,
but tear your back all apart.
Plus, muss up your hair for you.
On the farm they call it a "tedder".
It scatters the hay all over the
field for drying.
On second thought.
Just get a friend to scratch your back for you.
