Video of Electronic Tree to Tree Distance Marking System.

When the Photo-Eye senses the tree that was just planted, it signals a hydraulic solenoid valve to open a trap door, allowing the next tree to be planted. The door automatically resets itself and waits for the next signal.

The photo-eye is mounted to a telescoping boom that can be adjusted for different tree to tree spacing.
