The tractors are built in Case IH's plant in Fargo, North Dakota, where already 50,000 units[2] of this line were built as of September 2005.

This tractor line is powered by engines with 405 to 682 hp. They are available in wheeled, Quadtrac, and row-crop Rowtrac configurations, and are very closely related to the New Holland T9 range.

In 2005, the STX500 Quadtrac tractor set a new Ploughing World Record. The machine ploughed 321ha[2] in just 24 hours, led by Jean Imbert who drove the tractor.

In 2007, the STX530 Quadtrac tractor was featured on the television series Top Gear,[3] where presenter Richard Hammond chose the STX Steiger for some of the challenges, (eventually including ploughing.) It was lapped around the Top Gear Test Track by The Stig, finishing in a time of 4:49.1,[4] which is the slowest lap ever round the track.[5] In 2005 that model of tractor broke the 24-hour ploughing World Record,[6] turning 792 acres (321 ha) of farmland in just 24 hours.[7]
