How do seed planters work? First comes the tractor, which pulls the machine. Then the rolling coulter (the wheel that looks spiky) cuts a line into the ground. A wedge pushes into the line, creating a trench. Then Wade puts the seedling (a baby tree) into a rotating distributor, which plants the trees an equal space apart.
When you take home your Christmas tree this year, just think—your tree was probably planted eight years ago. What year was that? What were you up to when your tree was planted?
