When you’re running a high-capacity John Deere® STS or S-Series combine, you need unloading augers that can keep pace with modern harvest demands. Abilene Machine’s outer horizontal unloading auger is Made in the USA at our Kansas manufacturing facility, built tough enough for 22.50' systems and engineered for long-lasting performance. As an extended wear component, it’s designed to deliver the strength, precision, and reliability farmers count on. Each auger is computer balanced and laser aligned to provide vibration-free operation. That precision reduces stress on your bearings and gearboxes, extends component life, and keeps unloading quieter and smoother in the field. With a 163.5" overall length, 15" flighting diameter, 16" pitch, and shaft setup of 1 1/4" hex and 1 1/4"-19 internal spline, this auger is purpose-built for high-capacity unload systems. It’s a direct replacement for OEM Part Number AH203021.
