Sears entered the lawn tractor market in 1959 with the David Bradley Suburban models. The David Bradley name was dropped in 1964 and the Craftsman name was being used by the 1970s. Currently all Sears lawn and garden tractors are sold under the Craftsman or Craftsman Professional brand. A number of companies have built the tractors over the years, AYP and MTD providing the majority in recent years.
