With every Frontier sawmill, you receive a one-year consumer warranty.

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 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 OS35. 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 heavy-duty 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.
