Magnums, Steigers, Farmalls, Axial-Flow combines — Case IH iron carries a huge share of the work in our counties, and its owners ask us the same two things: make it pull like it should, and make the emissions system stop running the schedule.
Updated August 2026 · Ag’merica — we come to the farm · 260-355-1123
Magnum and Steiger tractors, Farmall utilities, Axial-Flow combines, Patriot sprayers — the modern FPT-powered ranges are regular work for our platforms.
Every calibration is built from scratch for the unit in front of us — same serial-number discipline whether it’s a half-ton pickup or a four-wheel-drive tractor. Your stock calibration is preserved before anything changes.
Case IH’s FPT diesels respond well to careful calibration — and they carry the same Tier 4 chain as everyone else, with their own fault personalities. We read them properly at the farm, complete the diagnosis before touching anything, and prove results with data instead of seat-of-the-pants claims.
Coverage runs across the modern Case IH diesel ranges, and it moves with software versions — the honest answer comes from checking your exact model and engine. Call or text 260-355-1123 with the model number and we’ll confirm yours, or try the lookup on the homepage.
Yes — that’s the whole model. We cover a 100+ mile radius of Fort Wayne, and a typical visit handles up to four units. See how farm visits work.
Calibration work is done within the machine’s safe margins and proven with data. On warranty: modifications can affect how a dealer treats claims — we’ll talk through your machine’s situation honestly before you decide.
