Choosing the right type or model of corn harvester may sound like a challenging task, especially with many options in the market. But before you make any investments, keep scrolling down to learn what you need to know about the right corn harvester for you and your operational needs.

Corn Harvester Brief History

Before WWII, most corn was harvested by hand. The first mechanical corn harvester was developed in 1930 by the Gleaner Harvester Combine Corporation. Researchers believe corn was developed by natives in Central America at least 7,000 years ago. It is domesticated grass, so it is not found in the wild.

Outside of North America, Australia, and New Zealand, “corn” means any cereal crop. Maize is the more formal and internationally recognized name for corn. Maize is an Indian word that means “sacred mother” or “giver of life.”

Corn Harvester FAQs

What is a corn harvester called?

A combine harvester, or combine, is the tool of choice for harvesting corn and other grains. This piece of equipment is called a combine because it combines several jobs into a single machine.

What does a corn harvester do?

A corn harvester is a machine used on farms to harvest corn, stripping the stalks about one foot from the ground shooting the stalks through the header to the ground. The corn is stripped from its stalk and then moves through the header to the intake conveyor belt.

What does a corn harvester cost?

Expect to pay somewhere between $330,000 and $500,000 if you’re buying new and paying the list price. The list price for new Case IH combines ranges from $330,000 to $487,000, and that’s for base models with no add-ons.

Is there a corn picking machine?

4YZ-3B self-propelled corn harvester combines corn picking, husking, husk chopping, straw returning, and corncob collecting into one unit. With a small turning radius, the harvester is well suited to a narrow road and small patches of corn harvesting. The machine can harvest three rows at the same time.

What is corn used for?

One bushel of corn contains about 72,800 kernels and weighs 56 pounds. The starch in corn can be made into plastics, fabrics, adhesives, and other chemical products. 40% of corn is used in ethanol production.

When to harvest corn?

Milk stage Harvesting

If you want that sweet, slightly crunchy, divine-for-roasting corn on the cob, you’ll want to harvest ears at the milk stage.

  • Predominantly sweet and occasionally dent varieties are harvested at this stage.
  • The milk stage is when the kernels are filled with milky-sweet sap, and it occurs about 18-20 days after the female silks appear and are wind-pollinated by the male tassels.
    Silking usually happens around 50-65 days after sowing seeds, depending on the variety and growing conditions.
  • To harvest maize in the milk stage, you’ll want to start watching it for signs of readiness at around 70-80 days after sowing.
  • Ears will be green and feel full and firm when you wrap your hand around them, and the silks will have a dried-out brown color.
  • To be entirely sure the kernels are ready, gently open the leaves and stick your fingernail inside a kernel. You should see sweet, milky sap – not a clear, watery liquid.
  • If you see the former, you’re good to harvest. But if it’s watery, cover the kernels back up and give the ear a few more days to mature.
  • To harvest the ears, grip them with your hand and gently twist or bend them down until they break off from the stalk.

Dry Harvesting

  • For popcorn, flint, flour, and dent varieties, most growers wait until the kernels are completely dry before harvesting.
  • That’s because popcorn needs a 13-14 percent moisture level to give it that perfect pop.
  • Flint, flour, and dent cobs are either used for decoration, fed to livestock, or ground into cornmeal or flour.
  • This maturing and drying process usually takes about 110-120 days.
  • But it’s worth the wait. Plus, it’s pretty easy.
  • All you have to do is wait for the maize to dry completely. The husks, silks, and tassels will all be brown.
  • The kernels should feel rock-hard, but too much or too little moisture can result in poor popping.

How to use a corn harvester?

  1. After the corn stalks are guided into the gap of the counter-rotating rolls, they will be pulled downwards by the rolls, and the corn cobs will then be snapped off for their large diameter.
  2. The corncobs are conveyed into the cornhusker by the lifting conveyor, while the flail knives chop straps to return to the field.
  3. Husked corncobs fall into the corncob tank while husks enter the corn husks chopping system and are chopped into small pieces.
  4. Chopped husks are discharged from the outlet on the side of the harvester and returned to the field. When the corncob tank is full, the driver can turn it over conveniently to unload the corncob.
