Husqvarna 540 XP® Mark III is a nimble and lightweight petrol chainsaw in the 40cc class, designed for professional tree care and thinning operations. The powerful engine combined with the optimal choice of SP21G or S93G chain delivers impressive cutting capacity with fast acceleration. The easy, reliable starts – cold as well as hot – and smooth manoeuvrability make this chainsaw a favourite for any tree care team.
Plenty of grunt during longer cuts
New engine design offers plenty of grunt for peak performance even during longer cuts. The high cutting capacity makes the saw ideal for productive operation – even when using a longer guide bar.
AutoTune 3.0 optimizes the engine settings and simplifies the starting procedure
Thanks to AutoTune 3.0, the engine settings are always optimized for maximum startability and performance in all conditions, keeping you going no matter the challenges. No need for manual carburetor adjustment.
Perfect sight critical for felling
Perfect sight is critical when felling – so we made one that will outlast the chainsaw itself.
Ergonomic design, easy to work with
No protruding parts, a smooth underside, rounded starter cover and well-protected controls all make the saw easy to handle.
Maintains performance, gives less wear
Give you full working days with maintained performance and less wear on the engine.
Optional Integrated Connectivity Device diagnoses the engine
Keep your saw and yourself up to date with Husqvarna’s digital services. Just plug in the optional Integrated Connectivity Device under the cover. Then you’re ready to connect and diagnose the engine.
