1. Beating with sticks/mallets (safflower, green gram, Urd, etc.)
2. Beating against stone or hard material (harrow body). E.g. Arhar.
3. Trampling under the feet of bullocks or wheels of tractor or bullock cart. E.g. Cereals, pulses,
4. By using threshing machines bullock (olpad), tractor or electric motor drawn. E.g. almost all crops.
