What is the difference between a thresher and a combine harvester?

Question

Tractor Gyan · Accepted Answer

A thresher is a machine that only performs the task of threshing, i.e., separating the grain from the harvested crop. On the other hand, a combine harvester is a multifunctional machine that reaps, threshes, and winnows the crop, all in one go. Their use depends on the scale of farming, budget, and desired level of mechanization.
