Corn planters are machines attached to tractors that cut trenches, drop corn kernels, and cover them with soil. They come in various sizes and models, with some equipped with seed sensors for better yield. Maintenance is crucial for successful farming. The largest corn planter is nearly the size of a football field and can cover multiple acres per day. The first corn planter was invented in 1850 and was made of wood.
Corn planters are horizontal devices attached to a tractor that automatically cut trenches, drop the corn kernels, and cover the seed with soil. The machines use a disc or drum that opens to release the seed, with a hydraulic blower to move each grain. Some are equipped with seed sensors that can control the spacing of each seed to ensure proper growth. When seed placement is controlled, it can produce higher yields for the farmer.
Various models and sizes of corn planters are available, depending on the farmer’s needs and how much equipment he can afford. Most corn planters can handle 12 to 30 rows in one pass across a field. Typically, this equipment includes tanks that hold fertilizer, with the largest units capable of carrying several tons of liquid and enough corn to cover more than 100 acres before refilling is needed. The farmer controls the speed of the planting process based on the efficiency of the corn planter, which is usually between 4 and 8 miles (6.4 and 12.9 km) per hour.
The largest corn planter is nearly the size of a traditional football field. These machines can cover multiple acres per day and are equipped with a global positioning system to adjust precise planting criteria. Corn planters commonly fold up so they can be carried from the barn to the field and require less storage space. They attach to the tractor with a ball and hitch.
George W. Brown invented a farmer’s first corn planter in 1850 that eliminated the need for a farmer to bend over when planting. These early models were constructed of wood, which ended the need for the farmer to carry a sack of corn over his shoulder. The patented corn planter used a trigger mechanism to release a kernel of corn into a hole made by the farmer with a stick. It wasn’t long before the equipment was modified with two hoppers planting two seeds simultaneously.
A critical component to successful farming with a corn planter is equipment maintenance. If the seed spacing is too close, the plant may wilt from lack of sunlight. When the grains are repeatedly not released from the drum, it can substantially reduce the crop yield. Depth control is also important to allow corn to germinate, especially when planting in fallow land.
