is a plough which cuts turns and in some cases breaks furrow slices by means of separately mounted large steel discs. A disc plough is designed with a view to reduce friction by making a rolling plough bottom instead of sliding plough bottom. A disc plough works well in the conditions where mouldboard plough does not work satisfactorily.

1- A disc plough can be forced to penetrate into the soil which is too hard and dry for working with a mouldboard plough.

2- It works well in sticky soil in which a mouldboard plough does not scour.

3-It is more useful for deep ploughing

4- A disc plough works well even after a considerable part of the disc is worn off in abrasive soil.

5- It can used safely in stony and stumpy soil without much danger of breakage

6-It works in loose soil also (such as peat) without much clogging.
