Introducing the revamped workhorse: The tried-and-true Frontier Sawmill returns with a bold, new look, maintaining its robust construction.

A bigger mill to tackle larger logs and heavier jobs.

The OS31 delivers the power and capacity to process logs up to 31 inches in diameter. Engineered with time-saving innovations like the patented Auto-Locking Sawhead and EZ Blade Tension to guarantee ease of use and straightforward operation. The standard track cuts boards up to 11', with optional 7' extensions available for longer logs. Stainless steel bunk caps prevent staining of valuable hardwoods. Operate at ground level with included leveling feet or elevate your log deck for a more comfortable working height with optional leveling legs. Customize the OS31 with a mobility towing kit, log loading system, and track extension options. You don't have to be a full-time pro sawyer to appreciate the capabilities of a machine that can do more.
