英文說明:This harrow is complete. This harrow was used after the fields had been plowed and the soil loosened with a comb harrow. Farmers then used a cutting harrow to cut the soil, while simultaneously flattening it. Cutting harrows came in various sizes. On flat land, cutting harrows were made somewhat longer. The knives numbered from 11 to as many as 25. On smaller fields or in hilly regions, these harrows were smaller, and had three, five, seven or nine blades. These two harrows include a seven blade and a three blade model. The blades are made of iron, but others were made of bamboo. These two harrows are complete.
