Big Iron sells construction and farming equipment such as combines, tillers, scrapers and balers, as of May 2015. It also sells and rents farmland through its partner company Stock Realty & Auction Co.
Big Iron operates both traditional and online auctions to allow private owners to sell farming and construction equipment. Its online auction is housed on its site, BigIron.com, and allows users to place custom bids on items based on the number of bids on an item and the value of the current highest bid. In order to place a bid through the auction, users need to register for an account with the site. This allows Big Iron to verify the identity of its bidders and manage payment information and transactions.
Users are able to search through all site listings based on relevant keyword or by navigating through categories based on the purpose of the equipment being sold. Listings in its online auctions typically include pictures of the equipment along with a description of the item's model number and condition. Listings also include information about the Big Iron Independent Sales Representative managing the sale. These individuals are not employees of Big Iron, but contractors overseeing the process and connecting potential buyers with sellers using the auction service.
