The legendary Frontier Sawmill is back—revamped with a striking new design and the same rock-solid durability you’ve come to trust. With capacity for logs up to 31" in diameter, the OS31 is purpose-built for larger jobs and tougher workloads. Packed with smart, time-saving features like the patented Auto-Locking Sawhead and EZ Blade Tensioning, the OS31 makes operation smooth, simple, and precise. Cut boards up to 11' long with the standard track, or go even longer with optional 7' extensions. Stainless steel bunk caps protect your hardwoods, while adjustable leveling options—ground feet or elevated legs—let you set up the way you work best. Expand your capability with optional add-ons like a mobility towing kit, log loading system, and additional track extensions. Whether you're a seasoned sawyer or just getting started, the OS31 delivers pro-grade performance without the full-time commitment.
