英文說明:These are comb-type harrows. After plowing, farmers used harrows to cut the earth into a finer texture and remove foreign objects. Oxen were used to pull these implements. The farmer held the harrow with his hands and thrust its teeth into the soil. The harrow handles are made of wood, while its 13 tines are made of iron bars. The points of the harrow tines became sharper with use. Both of these comb harrows are complete.
