A vertical shaft thresher has been developed to meet the need for harvest mechanization in the hilling regions of South China where the double-cropping system (paddy and wheat) is practiced.
" You are always trying to make me confess to all sorts of absurdities. Because I am improving my mind, of course, by seeing all these steam-ploughs, and threshing-machines, and chaff-cutters, and cows, and pigs, and sheep" .
There were no threshers there to thresh their poor old backs, or sword-fish to stab their stomachs, or saw-fish to rip them up, or ice-sharks to bite lumps out of their sides, or whalers to harpoon and lance them.
