The harvesting of Christmas trees for commercial purposes was initially a slow and tedious process. The cutting and tying of the trees alone required a considerable amount of time and manual labor. It was not until the invention of the first tree tyer that the whole process improved.

Developed by Marlin Tillaart,[1] the apparatus was intended for engaging and folding the limbs of the tree in a process known as tree baling. It features an opening and closing through the use of a concentric part and several circular tubes built within its frame.


During the tying of the tree, the gaps of the nested tubes are first aligned around the tree. The tree trunk is then enclosed within the frame by rotating the gaps that are out of alignment. This closed ring is then lifted to deflect the tree limbs upward,[2] folding the tree for easy baling.[3]

Because of the invention of the tree tyer, the process of tying trees has sped up considerably. Some manufacturers claim processing speeds of up to 40 trees per hour, saving time and manpower compared with the old procedure of bundling and tying trees by hand.
