Harvesting being done traditionally, using a binder. The wheat is cut whilst still a bit 'green', to retain the strength in the straw.
Here are four short video clips of a binder in operation. Click on each frame to view.
The resulting sheaves are stooked (shocked) up & left for 2-3 weeks to ripen. They are then carted in & made into a corn stack.
The stack is then threshed (thrashed) out at a convenient later date, in order to separate the grain from the straw.
