How does it work?
Sunflowers are collected by pans.
The adjustable pushing roll ensures sunflower plants are pushed forward. At the same time, the snapping roll (below the knife bar) pushes the stalks downwards. In this way, the cut is not performed until the sunflower heads are captured by the reel, preventing the stalks from being cut too soon.
As a result, only the flower heads reach the auger which finally delivers them to combine.
