2005 Case IH STX450 Quad Trac – High-Horsepower, Track-Driven Performance for Heavy-Duty Agriculture

The 2005 Case IH STX450 Quad Trac is a premium example of American engineering tailored for high-efficiency farming. With just 4,584 genuine operating hours, this low-hour beast offers a blend of raw power, traction, and comfort, making it an exceptional choice for farmers managing large acreage and heavy equipment workloads.

At the heart of this machine is a Cummins 400 horsepower engine, designed to deliver consistent torque under load, ensuring reliable pulling power across all soil types. The Powershift transmission makes operation smoother and more responsive, allowing for seamless gear changes even under heavy loads.

One of the standout features of the STX450 is its Quad Trac system, offering better ground contact and reduced compaction compared to wheeled tractors. The 30-inch rear tracks are in very good condition, while the front tracks are rated as average—ensuring balanced traction and durability in various terrains. These wide tracks distribute weight evenly, giving farmers the confidence to tackle wet, uneven, or soft fields without losing grip or sinking.

The four remote hydraulic outlets allow this machine to support a wide range of attachments, while the pin hitch increases its versatility for towing heavy-duty implements. The STX450 is also equipped with a comfortable cab, cold air conditioning, and excellent visibility, ensuring the operator stays focused and fatigue-free during long working hours.

The machine’s paint and sheet metal are in good condition, reflecting its well-maintained history and overall care. This tractor isn’t just about performance—it shows pride in ownership and readiness for the next productive season.

Whether you’re ripping, tilling, or pulling massive implements, the STX450 Quad Trac is designed to rise to the challenge. It’s a smart investment for any serious grower looking to expand productivity and minimize downtime.
