Groundnut is a common legume that is grown in several states of India. One of the most crucial steps in groundnut cultivation is threshing. Due to labor shortages during peak seasons, farmers suffer significant losses when threshing is delayed. An effort was made to create a groundnut thresher in order to solve labor issues during busy times and to ensure timely operation. The following parts should enable the groundnut thresher to carry out the intended tasks. Groundnut crop pods are separated from the vines using a thresher cylinder, concave and shifter unit. After threshing, a blower is used to remove the dust and chaff particles. Use a sieve to separate the pods from any foreign objects, like as vines. The prototype tractor-operated groundnut thresher achieved a maximum harvesting efficiency of 99.30 percent, a cleaning efficiency of 98.20 percent, and a minimum blown and broken pod percentage of 1.2%.
