Case IH 403 Combine Parts

The Case IH 403 combine was introduced in 1969 as part of Case IH's efforts to provide efficient and dependable harvesting solutions. Production continued through 1971. The 403 featured an IHC 291 engine with 95 horsepower and a 291 cubic inch displacement. Its separator relied on a conventional cylinder system, known for its effective threshing action. The grain tank capacity was approximately 65 bushels, with an unloading auger capable of emptying at a rate of around 25 bushels per minute. Farmers could equip the 403 with headers ranging from 10 to 15 feet in width, allowing for versatility in different field conditions. While chopper and spreader options were available, the focus was on efficient grain harvesting. The cab offered basic operator comfort and controls. The Case IH 403 excelled at harvesting grains such as wheat, soybeans, and corn, particularly in fields where maneuverability and reliability were paramount.
