levelling is done by using plough cultivator wooden plank harrow​

Answer 1

Tillage implements are broadly categorized into several groups depending on the purpose for which they are use:

Primary Tillage implements

Implements used for opening and loosening of the soil are known as ploughs. Ploughs are used for primary tillage. Ploughs are of three types: wooden ploughs, iron or inversion ploughs and special purpose ploughs.

Wooden plough or Indigenous plough

Indigenous plough is an implement which is made of wood with an iron share point. It consists of body, shaft pole, share and handle. It is drawn with bullocks. It cuts a V shaped furrow and opens the soil but there is no inversion. Ploughing operation is also not perfect because some unploughed strip is always left between furrows. This is reduced by cross ploughing, but even then small squares remain unploughed.
