Six models of Case IH Steiger and exclusive Quadtrac Series 4WD tractors deliver proven performance in challenging conditions. Case IH 4WD tractors feature two frame sizes and an industry-leading long wheelbase and drawbar design for superior conversion of horsepower to pulling power, while delivering superior comfort, convenience and reliability.
The 350, 400, and 450 are offered as a narrower, row-crop frame, while the 450, 500, 550, and 600 models come as either a heavy-duty wheel or in the Quadtrac design. With these models, there are 16 different versions, which have 390 up to 670 peak engine horsepower.
In addition, the AFS AccuGuide automated guidance ready system and AFS Pro 700 display are standard equipment on Steiger tractors for hands-free operation and improved farming efficiency. For maximum fuel efficiency, all Steigers utilize Selective Catalytic Reduction (SCR), where engine exhaust is treated with Diesel Exhaust Fluid (DEF), resulting in 10 percent overall fuel savings.
For improved flotation and traction with less compaction, the Steiger 350, 400 and 450 are exclusively available with the biggest tires on the market. Another Case IH exclusive is the 40-degree, right-hand swivel seat, which provides operators with a more ergonomic field of vision while also being able to monitor an implement behind the tractor. The new Steiger tractors also offer an exclusive, four-post cab suspension standard on the Quadtrac and optional on wheeled tractors to provide one of the best rides in a tractor cab.
