Husqvarna 450 petrol chainsaw

The Husqvarna 450 has taken over from the 350 which had the same engine as the 351, and with the exception of the crank case construction and a few minor differences it's virtually the same machine. We recommend this machine to ambitious firewood cutters and farmers. Whatever the job you come across the 450 has the power (there ain't no substitute for cc's) and the bar length (usually 18") to cope.

Second generation powerful all-round saw for people who value professional qualities in a saw. Starts easily also with a slower pull, comes with flip-up tank caps. The X-Torq® engine means lower fuel consumption and reduced emission levels. Auto return stop switch and visible fuel level makes the saw easier to handle. Equipped with Smart Start® and fuel pump to every time ensure easy starts.

One of our best selling saws used to be the 350 with an 18" bar, it was light, low vibration, and would pull well with an 18" bar.
A great all round saw, with the power for continual fire wood cutting.

Now with the 'X torque' evolution we have the 450. This will be our direct replacement.

The 450 has a little more HP than the 350, but with the 'X torque' engine is a real firewood machine.

Air Injection
Centrifugal air cleaning system for reduced wear and longer operating time between filter cleanings.


X-Torq®
Deliver lower fuel consumption and reduced exhaust emission levels in accordance with the world´s most stringent environmental regulations.

Quick-release air filter
Facilitates cleaning and replacement of the air filter.

Flip-up tank cap
The flip-up tank cap is easy to open and close when refueling.

Ergonomic rear handle
Increased comfort with soft inlay, ergonomic trigger and assymetrical handle.

Felling marks
Distinct felling marks for better felling precision.

Additional features

Snap-lock cylinder cover saves time when changing spark plugs and cleaning.
LowVib®
Effective anti-vibration dampeners absorb vibration, sparing the user's arms and hands.
Visible fuel level
Transparent fuel indicator makes it easy to check fuel level.
Inertia chain brake
Effective inertia-activated chain brake.
Three-piece crankshaft
Forged three-piece crankshaft for maximum durability for the toughest applications.
Smart Start®
The engine and starter have been designed so the machine starts quickly with minimum effort. Resistance in the starter cord is reduced by up to 40%.

Fuel pump designed for easy starting.
Auto return stop switch
Stop switch automatically resets to the ON position for trouble-free starting.

Pixel chain is standard for all medium and small saws. This is a narrow chain, but with 'pro' pitch .325 chain. This means a much thinner cut that most other saws. Less material removed = faster cutting and higher performance.

Air Injection is a ducting system that pulls only clean air from the flywheel fan = very infrequent air filter cleaning.

Gear Driven Chain Oil Pump - chain oil is quite viscous, mechanical feed ensures a positive delivery.

Split Body - a lower vibrating mass and cool fuel.

Inertial Chain Brake - if the saw accelerates hard (jumps) due to 'kick back' or 'push back' the brake will operate due to the back of your left hand hitting it. Also, the 'shock' will operate it (even if your hand is nowhere near it). No brake is guaranteed to work, but the Husqvarna brakes are the most effective I've come across.
