Frequently asked questions

What is the fuel mix ratio for the Husqvarna 525LS string trimmer?

The Husqvarna 525LS requires a 50:1 gas-to-oil mix ratio. For optimal performance, mix high-quality Husqvarna 2-stroke engine oil (or an equivalent) with unleaded gasoline. Using Husqvarna's pre-mixed fuel can also simplify the process and help maximize your engine's lifespan.

How much does the Husqvarna 525LS weigh?

The Husqvarna 525LS is incredibly lightweight, weighing just 10.14 lbs (4.6 kg), excluding fuel and cutting equipment. Combined with its 1.34 hp engine, it delivers the best power-to-weight ratio in the 20cc to 29cc pro-grade class, reducing fatigue during long landscaping shifts.

What trimmer head comes standard on the Husqvarna 525LS?

The 525LS comes standard with the T35X M10 trimmer head. This high-capacity, Tap 'n Go head allows for effortless line feeding by simply pushing the head into the ground while in use.

What is the cutting width of the Husqvarna 525LS?

The Husqvarna 525LS offers a wide 19.3-inch cutting width. This large cutting swath, powered by the high-torque bevel gear, allows you to clear wide paths of heavy grass and weeds efficiently, maximizing your productivity.

Is the Husqvarna 525LS built for commercial use?

Yes, the Husqvarna 525LS is a professional-grade trimmer built for commercial landscaping. It features a heavy-duty bevel gear, a metal skid plate for engine protection, a durable 7-spline solid shaft, and an efficient air filter designed for less wear and lower service costs.

How does the LowVib™ system work on the 525LS?

Husqvarna's LowVib™ design uses rubber isolation dampeners built into the handle to absorb engine vibrations. This keeps equivalent vibration levels incredibly low—3.0 m/s² on the front handle and 2.8 m/s² on the rear handle—ensuring operator comfort during all-day use.

Why is the Husqvarna 525LS so easy to start?

The 525LS features an Air Purge system that removes air from the carburetor and fuel system for quick starts. Additionally, it has an Auto-Return Stop Switch that automatically resets to the "ON" position after use, preventing frustrating flooded starts on the job.

What does "Connectivity Ready" mean on the 525LS?

The 525LS is Connectivity Ready, meaning it has an integrated service port compatible with Husqvarna's digital services. This allows commercial fleets to plug in and easily troubleshoot the machine, track service intervals, and monitor tool usage for improved fleet management.

Can I attach brush cutter blades to the Husqvarna 525LS?

Yes, the 525LS is versatile. While it comes with a trimmer head, it is compatible with heavy-duty accessories like the Husqvarna Brush Multi Blade (3-Tooth) for thick brush. Note that blades require the appropriate installation hardware and guards.

How big is the fuel tank on the 525LS?

The 525LS is equipped with a large 21.98 fl oz (0.65 L) fuel tank. Paired with the fuel-efficient 25.4cc X-Torq® engine, this larger capacity ensures longer runtimes, meaning fewer stops to refuel during major landscaping jobs.
