Word forms: plural harrows. countable noun. A harrow is a piece of farm equipment consisting of a row of blades fixed to a heavy frame. When it is pulled over ploughed land, the blades break up large lumps of soil.
On the underside of the harrow are blunt tines which comb through the grass, removing dead grass and scarifying the surface. Harrows are also useful if youâre seeding a paddock: harrow thoroughly; sow the seed: roll the surface with a Ballast Roller to firm the seed into the soil.n the underside of the harrow are blunt tines which comb through the grass, removing dead grass and scarifying the surface.
