Husqvarna 545RX Professional Petrol Brushcutter

Husqvarna Brushcutters:

In terms of brushcutters, the Husqvarna 545RX is definitely one of the best. Suitable for professionals working in landscaping, gardening or forestry, the brushcutter comes with a host of performance, ergonomics and durability features. Such features include X-Torq, LowVib and Smart Start Husqvarna technology, allowing for a higher level of performance, comfort and ease of start-up. The 545RX also comes supplied with a high-class Trio Balance ergonomic harness which makes operation over long periods much more comfortable – especially for on the back. It is vitally important when you are buying a Husqvarna brushcutter, that the amount of performance you get matches up to your job needs. The 545RX is built with a powerful yet robust Husqvarna 45.7cc E-TECH engine and utilises X-Torq design, increasing the engine power generated and helping reduce exhaust emissions by up to 75% – fuel consumption is reduced by up to 20% too. A 35-degree grass bevel gear utilises this power and can produce high torque that, while running in parallel to the ground, can increase performance even more. Ergonomics might be different from performance, but as the two work hand-in-hand it is just as important. Ergonomics are available in abundance on the Husqvarna 545RX. Take LowVIb technology for example – It utilises specifically positioned anti-vibration dampeners to reduce engine vibration on the brushcutter body. Less vibration means less tension and stress on the users’ hands and arms during long working periods. Maybe not as technological but equally important when buying a Husqvarna 545RX brushcutter is the harness. The Husqvarna 545RX comes with a Trio-Balance ergonomic harness built with broad back support, shoulder straps and a hip belt. Trio-Balance distributes the users working load over a larger area meaning a comfortable working position throughout. Other ergonomic features of the 545RX brushcutter are soft-grip handles and an adjustable, angled handlebar. A high offset post to increase freedom of movement for users working on slopes is another valuable feature of the 545RX. Engine start-up has always been one of the main factors to let traditional garden machinery down. With the Husqvarna brushcutter, Smart Start technology, fuel pump and an auto return stop switch have been added to decrease the strain on engine start-up. Smart Start actually works by reducing resistance in the starter cord by up to 40%, so less pulling is required when starting the brushcutter. The fuel pump works by removing air from the carburettor and fuel system that otherwise cause issues when using the pull cord to start a petrol engine up. The fuel tank level indicator on the 545RX is transparent, meaning you can easily keep track of when you need to refuel. An optimised centre of gravity improves balance thanks to an improved fuel tank position at the front of the engine. The trimmer head is also an important aspect of a Husqvarna brushcutter and luckily the 545RX comes with Tap n’ Go head and twin line cutting system, capable of adjustment through a simple tap of the head on the grass. The head can also be easily changed as a metal saw or grass blade can sometimes do a better job on dense areas such as bushes, woody growths and thistles. The cutting attachment combi-guard is extremely versatile and will work with either the grass blade or trimmer head.
