City dwellers may be surprised to find this name on the list, or may have never even heard of the store at all. This is because Tractor Supply Co. maintains a heavy presence in the rural sections of America’s more populous states, catering to both commercial and recreational farmers and ranchers. It’s just specialized and rural enough to avoid direct competition from category killers like Home Depot or all purpose retailers like Walmart, but has a broad enough appeal to support over 1,000 stores across the country.
