Practical, petrol-powered brushcutter with a J-handle that accepts both trimmer line and a grass blade. The 525RJX combines Husqvarna X-Torq® engine technology with Smart Start® and an auto return stop switch for straightforward starting and dependable cutting performance. Designed for reduced vibration and long work periods with an easily adjustable single harness.
Versatile cutting options
Combi-guard lets you switch between the T35 trimmer head and the Grass 255-4 metal blade so you can tackle long grass, tight edging and light scrub without swapping machines.
Low vibration, better endurance
Lowest vibration rates in its class reduces operator fatigue during extended use; soft-grip handles and a J-handle improve control and comfort.
Reliable starting and engine performance
X-Torq® engine design gives strong torque across the rev range. Smart Start® and Air Purge make starting easier, while the auto return stop switch resets to ON for trouble-free restarts.

Yes — if you’d like installation, let us know when ordering and we can arrange fitting (collection, workshop fit, or on-site depending on the product).
What fuel and oil mix should I use?
Use Husqvarna 2‑stroke oil or an equivalent 2‑stroke oil mixed at 50:1. The fuel tank capacity is 0.51 litres — mix fresh fuel to avoid starting and running issues.
