Question

What are the advantages of using a combine harvester for harvesting a crop

Answer 1

Mechanized harvesting provides the following advantages over manual harvesting:

Additional grain obtained: Mechanized harvesting eliminates grain loss during manual cutting of the crop, tying the crop for carrying, transporting the harvest and from incomplete threshing. A 5% to 10% increased yield has been demonstrated.

Time savings in the field: Our combine harvester can harvest and thresh one acre of land in one hour. The manual method would require 12 people, one full day to perform the same task, excluding threshing.

Reduced time to market: The manual method requires a separate step for threshing, which adds multiple days, and another day or two for cleaning. Thus the time from crop cutting to market ready is a week or more for the manual method as compared to an hour or so per acre for the combine harvester process.

Cleaner grain: the mechanized harvesting produces cleaner grain as compared to the manual process, for which the market often is willing to pay a premium.

Reduced net cost: the mechanized harvesting can be priced to be lower than the cost of manual harvesting.

It harvests the crop, threshes and cleans the grain from chaff. As it combines the activities of harvesting, threshing and winnowing, it is known as combined harvester. Use of CH helps in timely harvest of paddy. It takes less time, reduces the crop loss and helps the farmers to tackle the peak time labour shortage.
