First, the header, described above, cuts the crop and feeds it into the threshing cylinder. This consists of a series of horizontal rasp bars fixed across the path of the crop and in the shape of a quarter cylinder. Moving rasp bars or rub bars pull the crop through concaved grates that separate the grain and chaff from the straw.
A forage harvester – also known as a silage harvester, forager or chopper – is a farm implement that harvests forage plants to make silage. [1] Silage is grass, corn or hay, which has been chopped into small pieces, and compacted together in a storage silo, silage bunker, or in silage bags. [2] It is then fermented to provide feed for ...
Crop choice is central to any cropping system. In evaluating whether a given crop will be planted, a farmer must consider its profitability, adaptability to changing conditions, resistance to disease, and requirement for specific technologies during growth or harvesting. [2]
Silage must be firmly packed to minimize the oxygen content, lest it spoil. Silage goes through four major stages in a silo: [14] Presealing, which, after the first few days after filling a silo, enables some respiration and some dry matter (DM) loss, but stops. Fermentation, which occurs over a few weeks.
The first combines under that name, the All-Crop 60, had a 60-inch, sickle-bar cutting head, and the popular Model 66 had a 66-inch cutting head. Many of these units are still in working condition, and they are well known for their dependability and low maintenance; however, as they are quite small machines (and now very old), they are not ...

Contour strip cropping employs a crop rotation system down a slope to minimize runoff and rain velocity. [1] It is used mainly on gentle slope gradients. The width of protective strips is often higher than that of the row crop strips, so they may effectively intercept runoff.
The agricultural cycle is the annual cycle of activities related to the growth and harvest of a crop (plant). These activities include loosening the soil, seeding, special watering, moving plants when they grow bigger, and harvesting, among others. Without these activities, a crop cannot be grown.
