## Overview

Professional arborists and forestry workers demand reliability and performance from their equipment, and this Swedish-engineered chainsaw delivers both in spades. With its robust 50.1cc engine generating 4 horsepower, this professional-grade saw cuts through timber with impressive authority while maintaining the precision needed for demanding tree care operations.

Engineered for extended use in challenging conditions, it features low vibration levels of just 4-4.6 m/s² on both handles, reducing operator fatigue during long work sessions. The high-speed chain moves at 19.6 m/s with a maximum bar capacity of 50.8cm, making it versatile enough for both felling operations and detailed pruning work. At 5.31kg without bar and chain, it strikes an optimal balance between power and maneuverability that forestry professionals appreciate.

## Frequently asked questions

### What kind of user is the Husqvarna 550XP Mark II aimed at?

Husqvarna lists the 550XP Mark II for professional forestry and tree care. Its 50.1 cc engine produces 2.98 kW, or 4 hp, a high figure for that displacement, and it revs to 10,200 rpm. This is a saw for operators who cut for a living, not for a few tanks of fuel a year.

### What is the power-to-weight ratio of the Husqvarna 550XP Mark II like?

The Husqvarna 550XP Mark II weighs 5.31 kg without bar and chain while producing 2.98 kW, or 4 hp. Four horsepower carried on just over five kilos is what makes a saw feel willing rather than heavy, and that ratio decides how much cutting an operator gets done before fatigue sets in.

### Does the Husqvarna 550XP Mark II cut faster than the 545 Mark II?

On the figures yes, though the margin is narrow. The Husqvarna 550XP Mark II drives its chain at 19.6 m/s against 19.1 m/s for the 545 Mark II, and it holds more in reserve: 2.98 kW and 10,200 rpm versus 2.68 kW and 9,900 rpm from the same 50.1 cc displacement.

### How big a bar will the Husqvarna 550XP Mark II handle?

The Husqvarna 550XP Mark II takes bars up to 50.8 cm, turning 0.325 inch pitch chain. Half a metre of bar behind 4 hp covers most felling and cross-cutting in medium timber, and the 0.325 inch pitch keeps the kerf narrow so the engine spends its power on speed rather than width.

### Is the Husqvarna 550XP Mark II a noisy saw?

The Husqvarna 550XP Mark II is rated at 107 dB(A) of sound pressure at the operator's ear and 117 dB(A) of sound power. Both figures sit at the top end for a 50.1 cc saw: ear defenders are mandatory for the operator, and 117 dB(A) carries far enough to matter near housing.

### What fuel does the Husqvarna 550XP Mark II run on, and how much chain oil does it carry?

The Husqvarna 550XP Mark II runs on a two stroke mix at 50:1, never straight petrol, and carries 0.32 litres of chain oil in a separate tank. At a chain speed of 19.6 m/s that oil goes down steadily, so the level is worth checking at every fuel stop rather than once a day.
