Westfield 8-51



AGI Westfield's redesigned truck auger has been engineered to withstand the demands of farming today. The STX2 was built for durability, longevity and capacity. With the STX2, you’ll get the job done fast.

AGI Westfield has redesigned their mover kit to make set up as easy as possible. A breeze to move around the yard thanks to it’s joystick steering, the Self-Propelled (SP) kit also automatically adjusts the intake height when auger discharge is raised or lowered.

STX2 8

  • UP TO 3,500 BPH 
  • 31' - 51' LENGTHS


STX2 10 

  • UP TO 5,500 BPH 
  • 31' - 51' LENGTHS


Built for Durability

The STX2 features 12 GA tubing on 10" models, a heavy-duty motor mount designed to handle high horsepower, heavy auger engines, giving you the flexibility to use the engine you want.

Like all AGI Westfield augers, the flighting has been reinforced with Wear Edge Technology™, which provides an extra layer of steel welded to the edge at critical wear points to extend the life of your flighting.

The purpose-built hose routing provides a cleaner, sleeker look and protects the hoses from the elements, along with the powder coat paint which protects and provides a long-lasting durable finish. Heavy-duty hardened steel sprockets and high-speed roller chain are sized to match auger length and diameter, to help your auger perform at its best. A lubricated upper drive extends the life of sprockets and drive chain. The 10” models use square, one-bolt flight connections to ensure the flighting maintains proper alignment for smooth operation.

Designed for High Capacity

The STX2 uses double banded belts are molded together as one to transfer maximum power from the engine to the gearboxes to maintain consistent speed when the auger is running. To ensure optimal performance is achieved with longer units, the 10" in 46' and 51' lengths use triple banded belts.

Developed for Ease-of-Use

AGI Westfield’s STX2 is designed with end users in mind. The self-leveling motor maintains proper tension at all heights, so there is no need to reset the belt tension once the auger is raised into position. The electric clutch with remote allows you to start and stop the auger without shutting down the gas engine drives.
