How to Mechanise Crop Harvesting and Threshing Process

harvesting process

HARVEST being one of the most important steps in farming is referred to the cutting & collection process of plantations (generally crops). It is the season when you reap what you’ve sowed and is expecting to get the best of your hard work. 

It's the most awaited period when a farmer expects efficient harvest after all the pre-harvest hard work with minimal harvest loss. 

We all know that the harvesting season in India is celebrated with different festivals in different parts of India like Baisakhi, Onam, and Lohri etc. The farmers get the fruitful result of their efforts.

Farmers in India have traditionally been using different kinds of tools like a spade, shovel and sickle etc. Spade/Shovel for digging, ploughing or moving soil and sickle for the cutting of crop. However, the process is cumbersome & consumes a lot of time and manual labour to complete. As with modernisation in every sector, the farming process has also undergone advancements in mechanisation & automation solutions. With different kinds of tools & machines the harvesting process has become easy, convenient and time-saving. The tools/machines available in the market for harvesting are brush cutter and paddy harvester. 

brush cutter and harvester

Brush Cutters: A machine that is easier to carry on shoulders with an attached revolving blade for the cutting of crop & a paddy guard to make the cutting process efficient. The machine is generally used by marginal farmers who have smaller farmland up to 1 acre. Also the machine comes in different variants ranging from 2 stroke & 4 stroke engines in variable engine displacements. Brush cutters also come in electric motor variant whereas electric ones normally aren't very effective in the harvest of crops. 

Harvester: A bigger machine that runs on wheels with a much bigger engine, built to harvest crops across a much larger area up to 10 acres. The harvester machine comes in both petrol & diesel engine variants & the price ranges from Rs 80,000 to Rs 2, 00,000 depending on the brand & the model. 

Both brush cutter and harvester are highly beneficial in the harvesting process in terms of business efficiency, monetary returns & the consumption of time. These machines can be run single-handedly in a large farming area without employing any manpower and it requires comparatively less time to complete the work. As these are machine run and does not require any bare hand work, turns out to be safer for the person using it.

Let's check out how mechanisation affects the farming process:

harvesting process

• Time:  Sickle which is primarily used for harvesting has to hold with one hand and a bunch of crop from the other one and then the crop is cut above the roots. The entire process is definitely time-consuming and also requires a lot more energy whereas a brush cutter or paddy harvester machine just needs to be moved in the direction the crop has to be cut. Where the entire area would have consumed 2-3 days to be harvested manually the machine barely would finish it within a day.

• Money: Manual farming needs a whole lot of manpower depending on the area of farming so they’ve to pay accordingly for their work whereas a onetime investment in the machine can be run for the next number of years.

THRESHING which is also a part of the harvesting process is done to separate the edible part of the crop from the stalks. The manual process of threshing included Trampling, Pedal Thresher or beating the crop in a hardwood/block.

• Trampling:  In the process, the crop is spread in the floor and with the use of animals or bare feet the crops are tramped.

• Pedal Thresher: The process includes a threshing drum which rotates when paddled. When pedalled the drum rotates and the crop is threshed against it.

• Hardwood/block: The crop is beaten on the block and due to the force with which it’s beaten the grains separates from the crop.

In the mechanised threshing process, it is done by a machine which uses the process of convulsion.Let's checkout how mechanisation effects the farmings process:

How is manual threshing different from mechanised?

• Time: Manual threshing process consumes a lot of time as the process itself is tricky whereas in the mechanised process the work is done after the chaff is put in the machine and we get the grain and husk separated.

• Efficiency: In the manual process often the grain break or the crop doesn’t get separated completely resulting in loss whereas in the machine the crop and grain are separated completely and there’s no worry of the wastage.


We hope after reading this blog you will understand how mechanisation plays an important role in the harvesting process. It is always important to have a good yield and maximum harvest with a minimum loss of product, time and energy.
