About the HUSQVARNA 545RX Brushcutter

Professional Brushcutter Built for Demanding Daily Work

The Husqvarna 545RX is designed for professionals who need strong cutting performance and consistent reliability during heavy outdoor work. This powerful petrol brushcutter manages dense vegetation, large areas and tough ground with controlled and dependable strength. Its advanced design delivers excellent reach, smooth handling and stable performance across challenging environments. The machine is ideal for contractors who require long-lasting cutting capability with reduced fatigue during extended sessions.

Strong Engine Power for Tough Cutting Conditions

This model is equipped with a 45.7cc X-Torq® engine that provides impressive torque across a broad rpm range. The advanced engine design increases cutting output while reducing fuel consumption for improved working efficiency. The X-Torq® system also cuts harmful emissions, supporting cleaner operation for frequent daily use. The Smart Start system lowers starter cord resistance by up to forty percent, allowing easier starting with noticeably less effort. These engine features combine to deliver smooth and reliable power whenever demanding tasks require consistent performance.

Low-Vibration Operation for Improved Comfort

The 545RX includes LowVib technology, which reduces vibration reaching your hands and arms. This system uses advanced dampeners that absorb engine movement and create a more comfortable cutting experience. The soft-grip handles provide excellent control and stable handling during long periods of operation. An adjustable handlebar allows you to choose a comfortable working position, supporting better balance and improved posture. The forward fuel tank placement enhances machine stability, particularly on uneven areas or sloping terrain.

Ergonomic Harness for Long Working Sessions

This brushcutter is supplied with the Balance X Harness, designed to support long hours of continuous work. The harness features broad back support, padded shoulder straps and a comfortable hip belt that distributes weight evenly. This balanced system reduces strain on your body, helping you work longer with less fatigue. The harness also keeps the machine securely positioned, improving accuracy when cutting dense or awkward vegetation. These ergonomic features ensure greater comfort and enhanced productivity throughout busy working days.

Versatile Cutting Setup with Quick Equipment Changes

The 545RX is built to handle light trimming and heavy clearing tasks with equal ease. The combi-guard supports both the Tap’n’Go trimmer head and a durable metal grass blade, allowing smooth adaptation to different conditions. The magnetic locking pin holder enables quick equipment changes, helping you maintain strong workflow across large areas. The long shaft improves reach for wide sections, while the high offset post increases movement freedom on slopes or uneven ground. These features create an efficient and versatile cutting setup for many professional environments.

Durable Construction for Continuous Professional Use
