1680 parts and accessories
The Case IH 1680 combine, manufactured from 1986 to 1993, quickly gained popularity for its robust performance and efficient harvesting capabilities. Powered by a 210 HP engine, the 1680 offered header widths up to 30 feet, making it suitable for various field sizes. Its advanced rotary separator delivered impressive grain quality and throughput, setting a new standard for combines of its era.
The Case IH 1680 was a flagship rotary combine produced from 1986 to 1993, succeeding the 1480 series. Under the hood, it featured an International Harvester DT-466 210 HP turbocharged diesel engine with a displacement of 466 cubic inches. A key feature was its axial-flow rotary separator, characterized by a 30-inch diameter rotor for efficient threshing and separation. The grain tank boasted a capacity of 215 bushels, and it unloaded grain at a rate of 2.3 bushels per second (approximately 138 bu/min). Available header widths ranged from 13 to 30 feet, accommodating diverse harvesting needs. Chopper and spreader options were available to manage residue effectively. The cab was designed with improved operator comfort and controls for enhanced productivity. The 1680 excelled in harvesting a variety of crops including wheat, corn, soybeans, and other small grains, providing high capacity and minimal grain loss.
