Husqvarna 545 Mark II
Designed for professional forestry operations and demanding tree care work, this Swedish-engineered chainsaw combines power with precision handling. Its 50.1cc two-stroke engine generates 3.6 horsepower while maintaining a relatively lightweight 5.3kg frame, making it ideal for extended work sessions in challenging conditions.
The saw accommodates guide bars up to 50.8cm in length and delivers impressive chain speeds of 19.1 m/s, enabling efficient cutting through various wood types. Professional operators will appreciate the balanced vibration levels of 4.0-4.6 m/s² across both handles, reducing operator fatigue during prolonged use. With sound pressure levels at 106 dB(A) and a 0.32-liter oil tank capacity, this model strikes an optimal balance between performance and user comfort for serious forestry professionals.

Frequently asked questions
What is the Husqvarna 545 Mark II built for?
Husqvarna places the 545 Mark II in professional forestry and tree care. It uses a 50.1 cc engine rated at 2.68 kW, or 3.6 hp, and takes bars up to 50.8 cm, which covers felling, limbing and cross-cutting in medium timber day in and day out rather than occasional weekend work.
What separates the Husqvarna 545 Mark II from the 550XP Mark II?
Both saws share the same 50.1 cc displacement and weigh almost the same, 5.3 kg for the Husqvarna 545 Mark II against 5.31 kg. The difference is peak output: the 545 Mark II makes 2.68 kW and revs to 9,900 rpm, while the 550XP Mark II makes 2.98 kW and reaches 10,200 rpm.
How long a bar will the Husqvarna 545 Mark II take?
The Husqvarna 545 Mark II accepts a bar of up to 50.8 cm. Running that full length puts the most load on the 2.68 kW engine, so it is best kept for trunks that genuinely need the reach; a shorter bar on the same saw holds chain speed better and makes limbing less tiring.
How fast does the Husqvarna 545 Mark II move its chain?
The Husqvarna 545 Mark II runs 0.325 inch pitch chain at 19.1 m/s, with the engine idling at 2,800 rpm and topping out at 9,900 rpm. The 0.325 inch pitch cuts a narrower kerf than 3/8 inch chain, which suits a 50.1 cc engine that is asked to keep working all day.
Is 5.3 kg a lot for a saw like the Husqvarna 545 Mark II?
The 5.3 kg quoted for the Husqvarna 545 Mark II excludes the bar, the chain, the fuel and the 0.32 litre chain oil charge, so the saw in your hands is heavier. It is a two-handed ground saw: 5.3 kg is reasonable for 3.6 hp, but not a weight to hold above shoulder height.
How loud is the Husqvarna 545 Mark II and how much does it vibrate?
The Husqvarna 545 Mark II is rated at 106 dB(A) at the operator's ear and 115 dB(A) sound power, which makes hearing protection compulsory in practice. Vibration is 4.0 m/s² at the front handle and 4.6 m/s² at the rear, moderate figures for a 50.1 cc saw used for whole shifts.
