There are currently 20 OEMs in the North American tractor market. Despite the large number of suppliers, four companies—AAA, BBBB (), CCC and DDD—have a dominant presence. These four companies accounted for 84 percent of sales in 2016. In the past, BBB and CCC held commanding positions in the market, but the field has expanded over the years. Many of the entrants were foreign companies looking to expand. Some, such as India-based Mahindra, have a substantial global presence. Other foreign companies, such as Japan-based Kubota, have established a strong presence in the North American market. Some companies address niche markets, generally in the lighter horsepower category, while a few market their own brands and manufacture private label models that are sold in the United States. Although the number of companies entering or exiting the market has remained relatively stable in recent years, in 2009, four companies—Bobcat, McCormick, LS, and Yanmar—entered the North American market (although Bobcat exited in 2012).
