Here the grain was threshed and winnowed. They ploughed the land with oxen, harvested with scythes, and threshed it with flails. To clean the threshed seeds winnowing machines or rotational sieves could be used. It is threshed and winnowed after being dried for approximately one week. We see wheat being threshed, linen being spun and cotton being ginned. Others need to be threshed to separate the cash crop from the straw and chaff. The lower sieve separates clean grain, which falls through, from incompletely threshed pieces. To harvest jasmine rice, the long stalks are cut and threshed. In 2005, heads were harvested from every plant and threshed to remove the seeds. Once carried to the settlement, the grain was threshed. The result is that when threshed, the wheat ear breaks up into spikelets. The harvest could be stored in the barn and threshed during the winter. Teff is traditionally threshed by using animals walking on the harvest. The rice is then threshed and stored, ready for the mills. The spinifex is threshed until the resin particles fall free.
