The rake is to the horticulturist what the harrow is to the agriculturist. They both have the same object in view - namely, to level the surface of the ground, and break the clods into powder so that it may be easier and better for the sowing of seeds. The rake is useful for small areas, but the harrow (of which there are several varieties) is adapted for drawing over large areas. The heavier harrows are useful in clearing off the weeds, as are also the chain harrows, while the lighter ones are used in connection with seed sowing.
