Disc harrows are farming implements which are used to prepare the soil for planting or sowing by breaking up the clods and surface crusts, which improves soil granulation and also helps to destroy the weeds.

Disc harrows are of various types such as light disc, middle disc and heavy disc harrows.

The type of disc harrow as selected by a farmer depends on the purpose of disking, whether it’s intended for entering the crop residue or only for levelling the soil structure.
