Husqvarna 445S
Designed specifically for property owners who demand reliable performance, this Swedish-engineered chainsaw combines power and maneuverability in a well-balanced package. Its 50.2cc two-stroke engine generates 2.2 kW of power, delivering the muscle needed for felling small to medium trees, pruning branches, and cutting firewood. At just 4.99 kg without bar and chain, it strikes an ideal balance between capability and user comfort.
The saw accommodates bar lengths up to 50.8cm, though the recommended 45cm configuration provides optimal performance for most landowner applications. With a chain speed of 17.31 m/s and maximum engine speed of 9000 rpm, it handles cutting tasks efficiently while maintaining manageable vibration levels of 4.7 m/s² at the front handle. The 0.26-liter oil tank capacity ensures adequate lubrication for extended work sessions, making this chainsaw a dependable choice for property maintenance and occasional forestry work.

Frequently asked questions
What is the Husqvarna 445S built for?
Husqvarna describes the 445S as a landowner chainsaw designed to handle all your landowner tasks, and the specification matches: a 50.2 cc engine producing 2.2 kW, or 3 hp, behind a 45 cm bar. That is enough saw for firewood, storm clearance and felling medium trees on your own land.
What bar length can the Husqvarna 445S run?
The Husqvarna 445S has a recommended bar length of 45 cm and a maximum of 50.8 cm. At 45 cm the saw stays balanced and the 2.2 kW engine is not overworked; fitting the 50.8 cm maximum buys reach on thicker trunks but asks more of that same engine and makes the saw nose-heavy.
How much does the Husqvarna 445S weigh?
The Husqvarna 445S weighs 4.99 kg without bar and chain. Add the 45 cm bar, a chain, fuel and the 0.26 litre oil charge and the working weight climbs noticeably above 5 kg. It is a two-handed ground-work saw, light enough for a full firewood session but not for cutting above shoulder height.
What chain does the Husqvarna 445S use and how fast does it run?
The Husqvarna 445S runs a 0.325 inch pitch chain at 17.31 m/s, with the engine idling at 2,800 rpm and peaking at 9,000 rpm. The 0.325 inch pitch cuts a narrower kerf than 3/8 inch chain, so it works smoothly and suits the 2.2 kW on offer rather than demanding brute power.
How loud is the Husqvarna 445S and how much does it vibrate?
The Husqvarna 445S is rated at 106 dB(A) sound pressure at the operator's ear and 116 dB(A) sound power, so hearing protection is essential every time it runs. Vibration is 4.7 m/s² at the front handle and 4.6 m/s² at the rear, closely matched figures that spread the load evenly between both hands.
What fuel and oil does the Husqvarna 445S need?
The Husqvarna 445S burns petrol mixed with Husqvarna two-stroke oil, or an equivalent, at 50:1. Chain lubrication is separate and comes from a 0.26 litre oil tank. Fill that oil tank at every refuelling stop, because a 45 cm bar running short of oil wears both the chain and the bar rails quickly.
