Product Description

A portable sawmill with commercial production capability – The Peterson ASM (Automated Swingblade Mill) delivers consistent commercial production with little effort. Unlike a traditional bandsaw mill, our swingblade design allows the ASM to make horizontal and vertical cuts, changes the size or depth of the cut, and removes the previously cut board, all at the touch of a button by the operator. With the option to upgrade your control box to be wireless, it’s as easy as using your television remote. The drive speed is operated with a lever, which you push to move the mill forward, and pull to bring back. The large faceplate of the dial is easily visible at either end of the mill.

The ASM comes standard with a board remover, allowing you to push sawn timber to the far end of the mill, or drag the sawn timber back toward the operator, depending on your site lay-out, and is capable of shifting boards up to 220kg (488lbs). These features cement the ASM as the best portable sawmill available world wide. Like all Peterson production frames (WPF, DWS) the ASM can be upgraded to a ‘Giant’ frame, allowing you to saw even larger diameter logs, up to 2m or more. All this, combined with the many different power options available, makes the ASM a versatile and robust work horse for any commercial operation.


Controls at your Fingertips

All controls and adjustments for operating the Peterson ASM are located at the operators end of the sawmill. Ideal for fixed operation, full time commercial milling. No walking or pulling levers on the mill, just straight production.

World Leading Stability

The Peterson Hi/Lo track set up comes standard on the ASM and can be extended to any length at the time of purchase.
The Hi/Lo set-up provides the optimum structural design, where the two opposite corners of the sawmill are braced, providing the best stability, accuracy and safety. It also raises the track to avoid sawdust build up, allowing for easy access to remove shavings.

Electric Height Adjustment

Standard with the ASM model, the electric winch allows touch button control of the track height. Not only does it make for faster resetting, but sizing is more accurate due to raising and lowering the tracks at the same time.

100% Electric Option

Traditional gas powerred ASM models operate a main petrol motor from 25hp to 37hp. Petersons are proud to also offer a fully electric model with a 15kw 3 phase motor. Ideal for fixed use, indoor/workshop applications and low emissions.

Unbeatable Quality and Durability

Manufactured using high quality, hand polished stainless steel and aluminum, providing a virtually rust free sawmill. Using stronger, lighter materials also means the mills are robust in performance, and most importantly – have long-term durability in even the harshest conditions.

Accurate, Safe Sizing

All Peterson Portable Sawmills left/right sizing system is run by chain and sprocket, with a turning handle and lock. So that means it will only move when you unlock it, and you can position the sizing very accurately to within 1mm. No slippage, and top accuracy for every board.

Durable, Low Maintenance Blades

Our Peterson Blades last for 2-6 years with normal use and maintenance. However, some swing blade sawmill owners have been using the same blades for over 10 years! To decrease downtime, the Peterson blade can be sharpened while it is still on the mill; in less than 10 minutes, and without having to remove any guards.

Elevated Engines with Cyclonic Air Filters

We mount our sawmill engines higher than other manufacturers to ensure the air filter intake is further away from the sawdust output, helping prevent sawdust build up and overheating of the motor. Specifying Cyclonic Air Filters to separate clean air from debris and liquids also helps to improve the lifespan of your engine, with the added bonus that these filters last up to three times longer than standard duty filters.

Built to Last

All Peterson Sawmills are manufactured in our Rotorua, New Zealand factory and come standard with a 24-month return-to-factory warranty on the frame which includes all bed framing, track and carriage material manufactured by Petersons Global Sales Limited. We also offer an extended five-year frame warranty. This option can be included at time of purchase.
