[1] The aim of the device is to replace work that previously required hand-tying individual trees, most often used at commercial nurseries.
The baler then wraps or ties the branches to maintain a compressed shape for shipment and storage.
Simple machines are operated manually, usually requiring one person to push the tree through the funnel and another to wrap it.
