Chain-Reduction Auger Unit Information
The Lowe CL and XL-Series units are based on the Classic Chain-Reduction Series that has made Lowe the industry standard for decades. These auger drives feature pre-stressed, fully adjustable reduction drives and the strongest connecting links available. This is a design that will take the stresses of tough duty and thousands of pounds of twist force for years of dependable service. They are not limited to "lighter duty" applications.
