Gleaner S77 Combine Parts
S77 ) parts and accessories
The Gleaner S77 combine, produced from approximately 2007 to 2014, offered robust performance for grain harvesting. Powered by a Cummins engine delivering around 325 HP, it accommodated header widths up to 35 feet. Its efficient transverse rotary separator made it a popular choice for farmers seeking high throughput and grain quality, particularly in soybeans and corn.
The Gleaner S77 combine, part of the Super Series, was introduced to provide increased capacity and efficiency compared to previous models. It featured a Cummins QSC8.3 engine, typically rated around 325 HP, with an 8.3-liter displacement. The S77 utilizes a transverse rotary threshing and separating system with an axial flow rotor, known for its gentle grain handling and reduced losses. Grain tank capacity is approximately 300 bushels, with an unloading auger capable of discharging grain at a rate of around 3.3 bushels per second (approximately 200 bu/min). Available header widths range from narrow row crop heads to wide draper heads up to 35 feet. Factory options included various chopper and spreader configurations for residue management. The cab offered enhanced comfort and controls for operator efficiency, including advanced monitoring systems. The S77 is well-suited for harvesting a variety of crops, including corn, soybeans, wheat, and other small grains, excelling in high-moisture conditions.
