long note on agricultural implement
Answers
Combines might have taken the harvesting job away from tractors, but tractors still do the majority of work on a modern farm. They are used to push/pull implements—machines that till the ground, plant seed, and perform other tasks.
Tillage implements prepare the soil for planting by loosening the soil and killing weeds or competing plants. The best-known is the plow, the ancient implement that was upgraded in 1838 by John Deere. Plows are now used less frequently in the U.S. than formerly, with offset disks used instead to turn over the soil, and chisels used to gain the depth needed to retain moisture.
The most common type of seeder is called a planter, and spaces seeds out equally in long rows, which are usually two to three feet apart. Some crops are planted by drills, which put out much more seed in rows less than a foot apart, blanketing the field with crops. Transplanters automate the task of transplanting seedlings to the field. With the widespread use of plastic mulch, plastic mulch layers, transplanters, and seeders lay down long rows of plastic, and plant through them automatically.
After planting, other implements can be used to cultivate weeds from between rows, or to spread fertilizer and pesticides. Hay balers can be used to tightly package grass or alfalfa into a storable form for the winter months.
Modern irrigation relies on machinery. Engines, pumps and other specialized gear provide water quickly and in high volumes to large areas of land. Similar types of equipment can be used to deliver fertilizers and pesticides.
Besides the tractor, other vehicles have been adapted for use in farming, including trucks, airplanes, and helicopters, such as for transporting crops and making equipment mobile, to aerial spraying and livestock herd management.
The Five Main Types of Agricultural Implements. Because crop cultivation and farming involve heavy labor and a variety of different processes, it would be nearly impossible to do so by hand. ... Soil cultivation implements: used to plow the soil and prepare it for cultivation.
There is a wide range of agricultural equipment that is used in today’s farming: such implements can be purchased new or used, both through private sellers as well as through trusted farm equipment plow suppliers and manufacturers. In general, these implements can be divided into five primary categories, based on their use:
Irrigation machinery: helps to keep crops watered at appropriate levels, and usually includes central pivot irrigation systems and pump units
Soil cultivation implements: used to plow the soil and prepare it for cultivation. Some examples of soil cultivation equipment are spike, drag, and disk harrows; power harrow parts; mouldboard plows; and tillers in several varieties.
Planting machines: designed to plant saplings and seeds over broad areas of land, after the soil has been cultivated. Precision drills, broadcast seeders, seed drills, air seeders, and transplanting equipment all fall under this category.
Harvesting implements: used to bring in the crops once they have reached full maturity. Trailers, diggers, and pickers are a few examples of this kind of equipment.
Miscellaneous agricultural equipment: used in corollary agricultural activities, such as hay-making, shredding, and loading.
