It is a set of herds of cereal already dry and mature ( mostly wheat or rye or barley ) mowed sickle by gang of reapers gathering the harvest in the fields of Spain until not so many decades ago. This was how to proceed: the first Reaper opening gap reaping three furrows; putting the herds cut short on the ground mower on his back. He came back, some distance, second Reaper that deposited their herds over the past and so did all the gang of reapers. When all was check out a row of sheaves, that after another was tying with garanuelas or ties with care taken from own sheaves.
