The Case STX Steiger was a tractor line built by Case IH. This line continued the models built by Steiger Tractor, which was purchased by Case IH in 1986. The current model line is named Case IH Steiger.
The tractors were built in Case IH's plant in Fargo, North Dakota, from 2000-2008, 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]
