A66 parts and accessories

The Gleaner A66 combine, produced from 1975-1979, was a popular choice for farmers due to its reliability and efficient harvesting capabilities. Powered by a robust diesel engine pushing around 195 HP, it offered header widths suitable for various field sizes. This combine utilized a conventional cylinder and concave system, proving effective for a range of grains.

The Gleaner A66 combine harvester was manufactured from 1975 to 1979. It was powered by an Allis-Chalmers 301 cubic inch displacement, turbocharged diesel engine delivering approximately 195 horsepower. The A66 utilized a conventional threshing system, featuring a 45-inch wide cylinder with rasp bars and a matching concave to separate grain from the crop material. The grain tank capacity was approximately 165 bushels. The unloading auger offered a discharge rate of around 75 bushels per minute. Available header widths ranged from 13 to 20 feet for grain platforms and up to 6-row corn heads. Options included a straw chopper or spreader for residue management. The cab provided basic operator comfort and controls. The A66 was particularly well-suited for harvesting wheat, soybeans, and corn in fields of moderate size.
