Model HistoryEdit

Steiger Quadtrac front

The impressive front profile

These tractors evolved from the original high horsepower tractors developed by the Steiger company of North Dakota. Case IH bought them out in ? to expand there range at the top end to compete with the John Deere range. As a result of CaseIH owning Steiger, the Ford company had to change to Versatile for their high horsepower range to replace their Ford FW range of tractors, which were built by Steiger. They then bought Versatile to merge with the Ford New Holland agricultural division. But then sold New-Holland and the tractor division to Fiat. So when Fiat merged the New Holland operations with Case IH to form CNH Global part of the deal with the Monopolies and Mergers Authority in the EU was that some plants had to be sold an so the Versatile division was sold to Buhler of Canada, and the Steiger operations range was retained and expanded, but the classic Steiger Green was dropped for the Case IH corporate Red and Black livery.

The Range is offered in the conventional wheeled versions and with the flexible "Quadtrac" system that offers greater traction and lower ground pressure from 4 triangular track units that replace the wheels. The first Quadtrac model introduced in 1997 did not use the Steiger or STX branding, but was built in the Steiger facility and branded Case Quadtrac. The latest models no longer include the STX designation, and are simply Case IH Steigers. The Steiger brand was reintroduced in 2000 with the Prominent badge on the front.[2]

Record breakersEdit

In 2000 Case IH set a plowing record with a 9380 Quadtrac plowing 209.4 hectares (517 Acres) in France in 24 hours using a 17 furrow plow. Having lost the record Case IH then regained it in 2005 with a STX 500 covering 321 hectares (792 acres) with a 20 furrow plow.[3]

By 2005 50,000 STX tractors had been built (including Quadtrac models).
