Trackfarmer is a go-to source for Case IH STX Quadtrac replacement tracks and undercarriage. We sell a lot of 30″ and 36″ rubber for these machines — including Soucy Quadtrac STX belts (Trackfarmer sells more Soucy STX Quadtrac replacement tracks than any other company in North America), plus Camso, Firestone, Trackman, and quality used belts with % life listed up front.
Fits this family (STX Quadtrac): STX375QT, 425QT, 440QT, 450QT, 500QT, 380QT, 430QT, 480QT, 530QT and related STX Steiger Quadtrac models. Newer Steiger Quadtrac (non-STX) and Quadtrac 9300 have their own fit — text us your model if you are unsure. Magnum Rowtrac and Steiger Rowtrac are different systems; do not order STX belts for those.
We also stock midrollers, drives, idlers, seal kits, and tools from our wheels book. Trade-in used tracks? We often buy carcasses and can pick up when we deliver. Call or text for a delivered quote.
This can be picked up at our Long Prairie, MN location or we can ship to you. Please text/call/email for a quote including delivery, and the owner will respond quickly.
