Groundnuts are normally lifted and left in rows to dry out to 10% moisture for storing or 25% moisture for further mechanical drying. The combine then picks, cleans stems and collects the nuts into a collector tank or bags, moving at a rate of 3 – 7 km per hour.

The hand powered sheller will produce up to 1 ton of shelled maize an hour, graded into 2 grades by the size of grain.

This thresher is driven by a 3 – 4 h.p. petrol or electric motor. It will thresh from 200 1800 kg of grain an hour, depending on the type of crop. It is suitable for the small cereals such as wheat, oats, barley, rice, millet, and all types of field beans.
