Taken from CaseIH website; "Case IH customers can now extend their eligible tractor, combine, cotton picker and stationary engine warranties by using Case IH lubricants, filters, coolants and fluid analyses at the recommended service intervals. The new Ultra Shield protection plan offers a 10-year, 10,000-hour warranty." We signed up on this program when we traded in and bought our new STX's in the fall. It's all really easy, and either your dealer will come out and do the fluid analyses at your farm, or they give you the kit's to do it yourself and take it in for them to test.
