Interview Questions for Agricultural Machinery and Equipment

A combine harvester is a remarkable machine that performs three crucial harvesting operations simultaneously: reaping, threshing, and winnowing. Think of it as a highly efficient all-in-one system for grain harvesting.

Reaping involves cutting the crop from the field. The combine’s cutter bar, equipped with rotating knives, slices through the stalks at ground level. The cut crop is then conveyed to the next stage.

Threshing separates the grain from the plant material. The crop enters a rotating drum with concave bars. The drum’s action beats the grain loose from the stalks, heads, and chaff. This mixture then moves towards the next stage.

Winnowing, the final step, separates the grain from the remaining debris (chaff, straw). This typically involves a series of sieves and fans that use air currents to blow away the lighter chaff, leaving the heavier grain behind. This clean grain is collected in a hopper for storage or transport.

In essence, a combine harvester mechanizes a process that traditionally required numerous manual steps and a large workforce. This automation vastly increases efficiency and reduces labor costs in modern agriculture.
