Husqvarna 3120 XP Review

Husqvarna’s largest chainsaw is one of the most powerful in the world. The primary applications for the 3120 XP are extreme logging, portable sawmills, and stumpwork. This saw is designed to pull on the longest bars – up to six feet! Like all Husqvarna chainsaws, the 3120 XP has a superior power/weight ratio. Combine Smart Start with LowVib and ergonomic features, this heavy-duty saw is both easy to start and operate.


Quick-release air filter

Easily removable air filter, when you need to clean it or replace it.

Felling marks

Felling marks on the body are for lining up the bar to the cut. You line up the mark where you want the tree to fall with the felling marks and you do the top cut first.


Adjustable oil pump

You can control oil flow based on application and weather conditions.

Magnesium crankcase

Sturdily built crankcase withstands high RPMs and tough professional use. This ensures a long service life.

Three-piece crankshaft

Forged three-piece crankshaft for maximum durability for the toughest applications.



The vibration dampening system called LowVib is present in all Husky chainsaws. Metal springs in the engine suspension reduce vibrations felt by the operator. This allows you to work longer without your hands getting exhausted and it also prevents developing medical conditions.

The front handle and handguard are offset by 7° to provide a more natural holding position.

Inertia activated chain brake

In the case of kickback, the inertia mechanism will stop the chain from running. This significantly reduces the risk of injury.


Smart Start

Engine and starter design to start the machine quickly with minimum effort.


Probably the best thing about newer Husqvarna saws. It reduces emissions by up to 75% and fuel consumption by up to 20%. You spend less on gas and breathe fewer fumes. It also makes the saw CARB compliant.
