Harrow

Harrow, an agricultural implement, consisting of a frame with iron teeth, employed for smoothing ploughed land and covering seeds. A wooden frame was formerly used, but the whole implement is now usually made of iron. The most important varieties are the "brake," for breaking down hard soil, the "drill harrow," for pulverising between furrows of green crops, and the "chain harrow," composed of iron links, for covering seeds and eradicating weeds.
