What machinery and equipments are used for harvesting and threshing and which equipment can function both for harvesting and winnowing?
Manual harvesting tend to be slow and is normally done using simple hand tools such as sickles, knives etc. Therefore, the use of mechanized machines in harvesting operations increase the output in terms of crops harvested per unit time and the quality of the final product. Combine Harvester commonly known as 'combine' is a key invention that saves cost and time for farmers. Like the name suggests, this machine simply combines the three major harvesting operations reaping, threshing, and winnowing into a single process. Vertical conveyor reaper is used for harvesting and windrowing of wheat and paddy crops. Features: The combine harvester consists of cutting unit, threshing unit and cleaning and grain handling units. The thresher consists of threshing cylinder, oscillating box, straw walker, and winnowing and cleaning attachment. The rasp-bar cylinder is made of cast iron rings, sheet metal and toothed racks and is fitted on the main shaft running on two numbers of heavy pedal bearings. Thresher is productive farm equipment that threshes grain and removes the seeds from the stalks and husks. Harvesting is the process of gathering a ripe crop from the fields. Reaping is the cutting of grain or pulse for harvest, typically using a scythe, sickle, or reaper. On smaller farms with minimal mechanization, harvesting is the most labor-intensive activity of the growing season. The farm machine used to separate the wheat, maize, soybean, peans and other small grains and seed crops from their chaff and straw. The combine harvesters are used for harvesting of above crops using specially designed header. These are in use in advanced countries. Thresher is a machine to separate grains from the harvested crop and provide clean grain without much loss and damage. A combine harvester is used to perform all the functions that are winnowing, threshing, and harvesting. Harvesting is called a gathering a ripe crop from the fields. Threshing is the loosening of the crop from the husks and straw. Wind winnowing is an agricultural method that is developed by ancient cultures used for separating grain from the chaff.

A threshing machine or a thresher is a piece of farm equipment that threshes grain, that is, it removes the seeds from the stalks and husks. It does so by beating the plant to make the seeds fall out. Thrashing means ounding the sheaves against the wooden bars is performed to remove the grains from the stalks. While winnowing is the method of separating the unpleasant husk from food. It is achieved by pouring the grains on a windy day, from a height, when the grains fall on the ground and the chaff is swept away. The thresher consists of threshing cylinder, oscillating box, straw walker, and winnowing and cleaning attachment. The rasp-bar cylinder is made of cast iron rings, sheet metal and toothed racks and is fitted on the main shaft running on two numbers of heavy pedal bearings.
