Disc Harrow

Disc harrow is used to till the soil where crops are to be planted. It is also used to chop up unwanted weeds or crop remainders. The discs are also offset so that they are not parallel with the overall direction of the implement. Disc harrows are farming implements used to prepare the soil for planting or sowing by breaking up the clods and surface crusts, thus improving soil granulation and destroying the weeds. They consist of concave cutting blades (disks), mounted on a common shaft, that form a gang.
