'Threshing sledge' in the Bible

For dill is not threshed with threshing sledge, nor is a wheel of a utility cart {rolled} over cumin, but dill is beaten out with stick, and cumin with rod.

Look! I will make you into a new sharp threshing sledge, {with} sharp edges. You shall thresh and crush [the] mountains, and you shall make [the] hills like chaff.
