Professional Brush Cutter for Sale

The most notable aspect of the 545RXT-AT petrol clearing saw is its fantastic AutoTune™ engine. This design automatically adjusts the engine to optimise its performance at all times. As a result, the engine will perform perfectly no matter the climate you’re working in, the height you find yourself at, or the quality of the fuel in the tank. AutoTune engine technology ensures you are always able to get the most out of your professional brush saw. This engine is also extremely powerful thanks to the excellent X-Torq design. This is a 50cc engine that reduces emission by up to a whopping 60%, and is up to 20% more efficient with its fuel usage. Additionally, starting the 545RXTAT is very easy – just push the purge bulb, then the start button, pull the cord and you’re off!

To ensure that your brush cutting experience is the absolute best it can be, Husqvarna has packed the 545RXT AT chock full of features for convenience. The ergonomic handlebar is adjustable to get the perfect position, and uses a LowVib system that reduces vibration impacts on your hands and arms. The offset post provides additional leg space for more comfortable movement – especially on slopes –  and the frontal placement of the fuel tank helps to balance the machine when in use. This fuel tank is also transparent so that you can check the level at a glance.

The 545RXT-AT comes with an ergonomic harness to help you keep the machine close and safe at all times. The harness itself has broad back support for your comfort, as well as shoulder straps and a hip belt. All of this helps to disperse weight across the entire harness so you stay balanced. You can also adjust the back plate to better fit you. And if that weren’t enough, the harness also has an adjustable hook eyelet so you can better balance your link to the clearing saw.
