The XTA features 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 augers, the flighting includes 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 and powder coat paint to protect and provide 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 it's best. The chain tensioner on the top drive can be easily adjusted and provides consistent chain drive tension, helping to prolong the life of the chain.
