Ramp up your sawmill with a log loading system

Load and roll logs onto your Frontier sawmill more easily and securely with the winch and ramp options. Pass the winch cable over and around the log, connect it to the log deck frame, and operate the winch to roll the log up the ramps onto the bed. This system also makes rotating the log on the bed easy and securely holds the log for dogging. It enables one person to operate the mill alone with ease.

Add mobility and tow it right to your milling site

For sawyers working in multiple locations, you can tow the OS31 right to your milling site with the optional mobility kit and jack support package. This option includes the mobility subframe, axle, 12-inch wheels with quick release steel fenders, removable drawbar, six adjustable support jacks, and the carriage lockdown system. Add the mobility kit now, or upgrade your mill in the future when the time is right for you.

WHAT OUR CUSTOMERS ARE SAYING

still have questions?

What kind of Warranty do I get with a Frontier?

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 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.

How difficult is it to assemble my Frontier sawmill?

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.

How do I load logs onto my OS31 sawmill?

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.

Can I add a mobility towing kit to the OS31 sawmill?

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.

What is the maximum length of boards I can cut on the OS31?

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.
