Hello,

this is a machine used to mechanically pick cotton.
To do this, it has many rotating, moisturized spindles in each picker head which wind up the cotton and pull it out of the plant. A set of quickly rotating disks swipes the wound up cotton off the spindles. The cotton is then sucked into a basket through vacuum tubes.
The harvester I built also is equipped with a baler, so the harvester can build cotton modules while harvesting. When a bale is finished it can be carried on the tail gate until the harvester reaches an advantageous location where it can dump the bale onto the ground.

Enjoy!
