Pickers are individuals or machines that collect items, often in agricultural settings. They are commonly used in the harvesting of crops like fruits and vegetables. Human pickers manually gather produce, while mechanical pickers can efficiently harvest large fields, reducing labor costs and time. In addition to agriculture, pickers can also refer to those who collect items for resale, such as antiques or collectibles. These pickers search through various sources, including flea markets and thrift stores, to find valuable items that can be refurbished or sold at a profit.
