This efficient process ensures that the corn is harvested quickly and effectively, helping farmers save time and labor.
History of Corn Pickers
The history of corn pickers dates back to the 19th century, when labor-intensive manual harvesting methods were the norm. Before the invention of corn pickers, farmers would have to use a hand-held corn knife or sickle to cut each ear of corn individually. This process was time-consuming and required a significant amount of manual labor.
In the late 1800s, the first mechanical corn pickers were developed as a means to improve efficiency and decrease the labor required for harvesting. These early corn pickers were mounted on horse-drawn wagons and worked by mechanically removing corn ears from the stalks. However, they were still far from perfect and had several limitations.
One of the earliest successful corn picker designs was patented by Edmund Quincy in 1850. His invention consisted of a device that would pull the corn ears inward toward a rotating set of blades, which would cut them free from the stalks. The corn ears were then collected in a wagon attached to the picker. While this design was revolutionary at the time, it was limited in its ability to handle different corn heights and stalk sizes.
Over the years, various improvements were made to corn pickers, including the introduction of mechanical drives and more efficient cutting mechanisms. In the early 20th century, tractor-mounted corn pickers became popular, further increasing the efficiency of harvesting. These pickers were powered by the tractor’s engine and consisted of a series of rotating rollers and blades that would remove the corn ears from the stalks, separating them from the leaves and husks in the process.
With advancements in technology, corn pickers continued to evolve, becoming more efficient and capable of handling different corn varieties and field conditions. Modern corn pickers are now equipped with sophisticated sensors and automated systems that can detect ripe corn ears and adjust the picking mechanism accordingly.
In conclusion, the history of corn pickers reflects the continuous efforts of farmers and inventors to improve the efficiency and effectiveness of corn harvesting. From the primitive hand-held tools to the modern, high-tech machines, corn pickers have transformed the agricultural industry by significantly reducing the labor required for harvesting corn.
Components of a Corn Picker
When it comes to the efficient harvesting of corn, a corn picker is an indispensable piece of machinery. The corn picker is made up of several important components that work together to maximize productivity and minimize labor. In this article, we will explore the various components of a corn picker and how they contribute to the harvesting process. Let’s dive in!
1. Cutterhead
The cutterhead is the foremost component of a corn picker and is responsible for cutting the stalks of the corn plants. It consists of a series of rotating knives or circular saws that are strategically positioned to slice through the corn stalks at the desired height. The cutterhead is adjustable, allowing farmers to customize the cutting height according to the specific conditions of the field. This flexibility ensures that the corn picker can effectively harvest corn plants of varying sizes.
2. Gathering Unit
The gathering unit of a corn picker is responsible for gently pulling the cut corn plants into the harvester for further processing. It is typically located below the cutterhead and is equipped with rows of gathering chains or augers that rotate and create a pulling action. These chains or augers transport the corn plants towards the snapping rollers, which remove the ears from the stalks. The gathering unit plays a crucial role in efficiently and effectively collecting the corn plants and preparing them for the subsequent stages of the harvesting process.
3. Snapping Rollers
The snapping rollers are an essential component of a corn picker as they are responsible for separating the ears from the stalks of the corn plants.

The snapping rollers need to be carefully adjusted to ensure that they exert enough force to separate the ears without damaging them. This delicate balance ensures that the corn picker can efficiently harvest the corn while preserving the quality of the ears.
4. Husking Unit
Once the ears have been detached from the stalks, they are transported to the husking unit of the corn picker. The husking unit consists of rubber belts or rolls that remove the husks from the ears. As the ears pass through the husking unit, the friction between the rubber belts and the husks causes the husks to be pulled away from the ears. This process ensures that the harvested corn is free from husks, making it ready for further processing or storage.
5. Cleaning System
After the husking process, the corn undergoes a cleaning system within the corn picker. This system removes any debris, such as leaves, tassels, or remaining husks, from the corn kernels. Usually, this is achieved with the help of fans and screens that allow the lightweight debris to be separated from the heavier corn kernels, ensuring a clean crop output.
6. Chopping Device
In certain instances, farmers may choose to chop the remaining corn stalks for various purposes, such as for use as livestock feed or to facilitate the future cultivation process. For this purpose, some corn pickers are equipped with a chopping device located at the rear of the machine, behind the gathering unit. This device chops the stalks into smaller pieces, which can be spread evenly across the field or collected for other agricultural uses.
Understanding the various components of a corn picker provides valuable insight into the inner workings of this essential harvesting machinery. Each component plays a crucial role in ensuring the efficient and effective collection of corn plants.
