Farming has totally changed. The most significant technological change one can notice in agriculture now is the combine harvester. This fantastic machine reduces the amount of labor applied during harvesting by a good margin but increases the levels of efficiency and productivity severalfold. So how does a combine harvester really work, and what's so great about it for farmers? Now, let's have a closer look at the functions of the combine harvester as well as the benefits brought about to modern agriculture via this fantastic technology.

What is a Combine Harvester?
Combine harvester is the multiple function harvest machinery which is used to effectively harvest multiple crops, for example grains such as wheat, rice, corn, barley, and oats. The word "combine" in its name already speaks to the three main harvesting processes it performs, which are reaping, threshing, and winnowing. Hence, this powerful machine replaces the requirement of having many tools and arduous manual methods by farmers; therefore, the harvesting of crops by them can be performed with very minimal effort and time.

In most places where rice is the primary crop, there are specialized models referred to as rice harvesters. These are designed strictly for paddy fields since the nature of the soil in such areas often tends to be wet and muddy. Having this in mind, the parts of a rice harvester are built to work best with such conditions.

How a Combine Harvester Works
A combine harvester works upon performing three related operations in one single operation:
Reaping is the first process that is engaged in the harvesting, that is cutting crops off from the field. The large header of the combine harvester on the front cuts crops as it moves ahead. Its width depends on its size and model, thus significant parts of the field can be cut at a time by the farmers.

Threshing:
After cutting this crop is conveyed to the drum of the harvester. Threshing is the separation of grain from the stalks and husks. In the drum, there are rotating rods that beat up the crop letting the grains fall off without getting damaged. This is also one step that collects the edible part of the crop.

Winnowing
Winnowing then begins once the grain has been separated. Chaff and straw are blown away by air currents in a combine harvester to leave clean usable grain. The separated grain is collected within a large storage tank, whilst the rest of the plant material may be shot back out into the field or collected later at the discretion of the farmer.

The same basic operation in some specialty crops, for example rice production, is dealt with by a specialized rice combine harvester that is suitable to the specific needs of rice production, such as working in flooded paddy fields and gentle handling of fragile rice grain.

Major Components of a Combine Harvester
To know how effectively the machine performs, one must know the major parts of a combine harvester:

Header: This is the forepart of a reaper and is specially designed to cut crops. There are various types of headers and use one that best suits the type of crop. A paddy cutter will need a specific type of header in the shape of paddy stalk cutting under waterlogged conditions.

Threshing Drum: Here, mechanical action is made for the separation of grains from the stalks.

Grain Tank: Grains are transferred to a grain tank that can be towed to trucks or carts by the combine with a rolling action.

Straw Chopper/Spreader: The chaff and other plant material can be chopped up and applied over the field as mulch or baled for different uses.

Advantages of Using a Combine Harvester

Save more time and labor
Probably, the greatest savings with a harvester is time and effort. Conventional harvesting involves a multi-step process that requires hand effort over a period of days. This whole job can be done by one machine, a combine harvester, within a much shorter period of time. Big fields are harvested in one day, and all operations are done much more efficiently.

Higher Yield and Losses
Crop harvesters do not break the crops and separate the grains without breaking off. The traditional methods of harvesting usually result in losses due to improper handling. But in the combine harvester, the process goes with precision and control so that there would be minimal grain loss and higher yield.

Flexibility
What is very fundamental to the design of a combine harvester is its ability to harvest many varieties of crops. For instance, it can be multi-purpose, where without changing the headers or setting different settings, it can be used for wheat, rice, and barley grains. This versatility makes it one of the best investments any farmer can make if he harvests different crops season after season.

Economical
Although acquiring the combine harvester seems very costly, the saving attracted in the long run pays out much. It saves many manual labor works that are continually increasing and getting too expensive and unattainable to be done. On the other hand, through the increment of the ratio in the productivity of the machine, it reduces the grains' waste to enable the farmer recover the investment within a short period.

Less Post-Harvest Labor
All post-harvest processing has been done by a combine harvester in one go. In traditional approaches, all these have to be threshed, winnowed, and transported by hand. With all these done, lots of time and labor have to be spent. All these will be done by a combine harvester in one go. As such, all other post-harvest processing has been reduced. Thus time is saved, with much time allowed with agriculture to do other important tasks.

Specialized Rice Harvesters
Rice harvester is highly useful in effective farming because it tackles the specific challenge that affects within the paddy field areas, which essentially are wet and muddy. A rice harvester would move on such terrain without getting stuck there and harvest fragile rice grains without breaking them. Such specialized machines are pretty indispensable for heavy rice cultivation areas and maximizes production while minimizing manpower.

Conclusion
There is one machine in modern farming that made the entire process of cutting, separating, and collecting into a much easier and faster fashion to obtain grain-the combine harvester. All these attributes: flexibility, saving more time in the field, and minimizing grain loss-more than justify it as a necessary tool for any farmer's arsenal around the world.

These machines, together with the type of rice harvester, will ensure the good harvest for the rice farmer regardless of what the field conditions are. The value added far exceeds merely saving time and labor; they yield better crop output, quality, and profitability. Further steps forward for a machine like the combine harvester and the rice harvester will come to agriculture, making its way toward sustainable agriculture and advancing productivity.

This can therefore make advanced technologies available to farmers, who in their turn will be able to enjoy better benefits from the hard work and investment put in.
