On large and modern farms, harvesting is done with the most expensive and sophisticated farm machinery, such as the combine harvester. A specialized harvesting equipment utilizing conveyor belt mimic hand picking and replaces the manual task of removing each seedling by hand. The completion of harvesting marks the end of the growing season, or the growing cycle for a particular crop, and it is the focus of seasonal celebrations such as harvest festivals.
