Husqvarna 3120XP Chainsaw (Power Head Only)

The Husqvarna 3120XP is the largest chainsaw Husqvarna makes, a 118.8 cc power head for the biggest wood you will ever face. It is sold as a power head only, so you pick the long bar and chain that suit your work, whether that is bucking huge trunks or running an Alaskan-style mill.

What the 3120XP is for

Most tree work never needs a saw this size. A 70 cc or 90 cc saw handles nearly every removal. The Husqvarna 3120 XP is for the jobs where those saws run out of bar or out of power: old-growth trunks, huge oak and sycamore butts, big stumps, and slabbing logs into lumber with a chainsaw mill.

Because it is sold as a power head only, you set it up for your work. Crews that buck big wood usually run a long bar with a full-chisel or semi-chisel chain. Millers often run an even longer bar with a ripping chain. Check Husqvarna's bar recommendations for the saw and match sprocket, pitch and gauge before you order.

That flexibility is also why the 3120XP shows up at sawmills, on storm crews dealing with blown-over giants, and with timber framers who need to square up large beams. It is a specialty saw, but in the right hands it is the only tool that makes some cuts possible.

Power and handling

With 118.8 cc and roughly 8.4 hp, the 3120XP pulls a long bar through dense wood without bogging. That is its real job: keeping chain speed up when there are 36 inches or more of bar buried in a log. It is heavy, at about 22.9 lb before you add a bar and chain, so it is a saw you work from the ground, braced and on good footing.

The decompression valve makes starting a saw this size manageable. Even so, plan your starts on the ground with a firm grip and the chain brake on. On long cuts, let the saw do the work and keep the chain sharp. A dull chain on a saw this big just makes heat and dust.

Run it at full throttle when cutting and do not lug it. Big two-strokes stay healthier when they spin freely. Clean the air filter and cylinder fins often, because long cuts in big wood make a lot of fine dust, and check the sprocket for wear every time you change a chain. On milling setups, watch bar oil closely and consider an auxiliary oiler on very long bars.

Safety with a big saw

Big bars mean big kickback zones. Wear chainsaw protective chaps or pants, a helmet with face and hearing protection, gloves and cut-resistant boots. Know where the bar tip is at all times, and never use a saw this size above shoulder height. Anyone running it should be trained in felling and bucking large wood and follow ANSI Z133 practices on tree jobs.

Large-diameter wood also stores a lot of tension. Read the log, plan your relief cuts, and keep the helpers clear of the roll zone.

Is it the right saw for you

If you regularly cut wood that is wider than a 36-inch bar can handle, or you mill slabs, the 3120XP is worth its price. For general removal work, a Husqvarna 395XP or a 572XP will be lighter and faster on most of the day's cuts.

Think about the rest of the job too. A saw this size needs a truck or a trailer, a way to move huge rounds, and a crew that knows how to roll and wedge big wood safely.
