In Central and Northern Europe, its use can not be proven.

The flail other hand, is an improvement in the expenditure of force, since the rotation of the flail to accomplish with less force than hitting with a Dreschstock. Flail are demonstrated in the Old Kingdom of Egypt, among other things as an attribute of fertility on pictures of Osiris. They were used until the mid- twentieth century.

(Also called Dreschwalze ) The Dreschblock further simplifies the work. It is a conical roller which is pulled by a horse in a circle on the grain. One such device is shown in the Museum Cloppenburg and explained.

In modern times, these devices were replaced by threshing machines, which ultimately led to the development of the mobile combine. This now has different Headers depending on harvest Direction fruit.
