Words with which you might wish to label Husqvarna’s 450 rear handle chainsaw include “hefty”, “beefy”, “mighty”, “strapping”, “doughty”, “muscular” and “vigorous”. This, in short, is a machine with plenty of clout, and one of the most powerful residential use chainsaws available from Husqvarna’s extensive range. Ideal for frequent heavy duty firewood cutting, felling and pruning larger trees, and all general residential, agricultural and estate maintenance work, the 450 is therefore undoubtedly one of the most pleasingly effective chainsaws in its class available today.
A good deal of this excellence is attributable to the potent 50.2cc X-Torq® two-stroke petrol engine, which delivers enough power for a maximum chain speed of 17.34m/s. Husqvarna’s innovative X-Torq® technology boosts performance further by improving the combustion process, which simultaneously reduces emissions by up to 75% and increases fuel efficiency by around 20%. The 450 can therefore outperform pretty much any comparable saw fitted with a conventional two-stroke engine, while also offering a superbly user-friendly working experience. This outstanding convenience is further underlined by the inclusion of an auto-return stop switch, a primer bulb and an enhanced Smart Start® system which reduces starter cord resistance by 40%, thus ensuring quick and hassle-free starting every time.
Fitted as standard with a 45cm (18”) bar and .325” pitch chain (can also be fitted with a 37.5cm/15” bar), the 450 excels when faced with even the most challenging residential cutting work. Felling trees, for example, is made much easier by the inclusion of a practical tool-free chain tensioning system and felling guidance marks on the machine casing, thus ensuring optimal cutting performance and allowing you to direct a falling tree with reassuring precision. A brilliantly effective inertia-activated chain brake, moreover, provides vital protection against dangerous kickback events.
As it is designed for home users the 450 is also remarkably easy to operate, certainly more so than you might expect of a chainsaw with such impressive cutting power. The high capacity 0.45 litre fuel tank, for example, extends run time between fuel stops and features a clever transparent window and flip-up cap to make refuelling pleasingly quick and simple. An innovative LowVib® anti-vibration system and an ergonomic rear handle with a soft inlay, meanwhile, allow you to work for longer in complete comfort, with features such as the centrifugal air cleaning system, a quick-release air filter and a snap-lock cylinder cover all helping to ensure reliable performance by facilitating routine maintenance. Even less experienced users can therefore rest assured of consistently superior results. Even better is that Husqvarna’s engineers have designed the 450 to be a tough little beast, with high quality components such as the forged three-piece crankshaft ensuring incredible durability and a longer service life.
