After ploughing, a harrow is drawn across the field to crush clods, uproot weeds, and create a finer seedbed. Older harrows were simple wooden frames fitted with iron teeth, while later forms use discs or powered mechanisms. In poetry the tool evokes agricultural cycles, spring preparation, and the rough labour required before growth. Its dragging teeth also carry painful associations, making harrowing an image of torment, grief, or memory repeatedly raking the mind, even as the literal act prepares earth for renewal.

The harrow normally follows the plough, breaking clods, removing weeds, and preparing a finer seedbed. Understanding this sequence helps students interpret agricultural imagery accurately. In poetry the harrow represents both injury and preparation, since its teeth tear through soil so that future growth becomes possible. The related verb harrow means to distress or torment, reinforcing emotional associations. Related terms include plough, sowing, seedbed, furrow, soil, cultivation, teeth, torment, preparation, renewal, farming cycle, and the disturbing of what has settled.
