OS31 Portable Sawmill

With every Frontier sawmill, you receive a one-year consumer warranty. We will repair or replace, at our discretion, any part returned to us and found to be defective through manufacturing within the first year of the original purchaser’s ownership (except consumable items like belts, blades, bearings & clutch). The engine is covered under warranty directly with the engine manufacturer (two years by Briggs and three years with by Kohler). We back that up with a 30-day money-back guarantee. If your Frontier sawmill doesn’t do everything we say, simply return it to us within 30 days and receive a refund (shipping not included)*.

*Not including used blades, damaged parts or restocking fees.

The sawhead is pre-assembled at the factory, and thanks to the fully illustrated step-by-step manual with exploded illustrations, diagrams, and photographs, the rest can usually be put together in a single day. You'll only need a few basic tools, including combination and Allen wrenches, a ratchet with SAE and SI sockets, an adjustable wrench, a Phillips screwdriver, a drill, lubricating and engine oils, and a grease gun. Regardless of your skill level, Frontier Sawmills are designed to be user-friendly and easy to operate. We also provide toll-free support from the moment your Frontier Sawmill arrives, through your first cuts, and beyond.

Some sawyers have their own tractors or loaders. If you don't have access to such equipment, you have the option to enhance your setup with the available log loading systems designed for the Frontier OS31. This includes a ramp package for efficiently moving logs onto an elevated sawmill bed. To further streamline the process, you can complement it with a log winching system. This system facilitates the movement of logs onto the sawmill bed and includes a log turning hook for rotating heavy logs and cants and hold them firmly against the log posts for dogging.

Yes, with the optional Mobility Kit you can tow the OS31 sawmill through your woodlot and directly to your sawing site. This includes a steel sub-frame, wheels, a quick-disconnect drawbar, running lights, wiring harness, safety chains, and support jacks. Additionally, there's an option to add a mobility kit sub-frame extension with extra jacks to support a 7 ft extended log deck. You can add the mobility kit now or choose to upgrade your mill in the future.

Standard, the OS31 band sawmill log bed is 14 feet long (4.3 m), which allows you to makes cuts up to 11 ft (3.4 m) in length. To saw longer material, you can add optional 7 ft (2.1 m) log deck extensions. You can add multiple extensions in stationary configuration to cut logs of any length. If you want to add the mobility towing system to your Frontier, you can still add one 7 foot bed extension and have it supported with the mobility sub-frame extension kit.
