Frequently asked questions

What attachments are compatible with the Husqvarna 525LK string trimmer?

The Husqvarna 525LK is a versatile combi machine compatible with over a dozen "click-on" attachments. You can easily swap the trimmer head for a pole saw, hedge trimmer, lawn edger, cultivator, sweeper, blower, or weed scissor, making it a multi-purpose tool for year-round landscaping. Check out the selection here: https://www.husqvarna.com/us/trimmer-attachments/ 

Is the Husqvarna 525LK built for commercial use?

Yes, the Husqvarna 525LK is designed specifically for commercial use. Despite weighing only 9.92 lbs, it features a powerful 1.34 hp X-TORQ® engine and heavy-duty components built to withstand full-time, demanding landscaping jobs.

What is the correct fuel mixture for the Husqvarna 525LK?

The Husqvarna 525LK requires a 50:1 fuel-to-oil mixture. For optimal performance and engine longevity, it is highly recommended to use Husqvarna brand 2-stroke oil mixed with high-quality, unleaded gasoline (minimum 89 octane).

How much does the Husqvarna 525LK weigh?

The powerhead and shaft of the Husqvarna 525LK weigh just 9.92 lbs (excluding the cutting equipment). Its lightweight design and comfortable loop handle reduce user fatigue during long hours of operation.

How does the Smart Start® technology work on the 525LK?

Husqvarna’s Smart Start® technology is designed so the engine starts quickly with minimal effort. Resistance in the starter cord is reduced by up to 40%, and the Air Purge system removes air from the carburetor and fuel system, ensuring reliable starts every time.

What trimmer head comes standard with the 525LK?

The Husqvarna 525LK comes standard with the T35 M10 Tap'n Go trimmer head. This heavy-duty head features an easy-to-use line feed system that automatically advances the trimmer line when pushed into the ground.

Does the Husqvarna 525LK include a shoulder strap or harness?

No, a harness or shoulder strap is not included with the standard Husqvarna 525LK package. However, it features an ergonomic, soft-grip loop handle designed for comfortable, unharnessed maneuvering. A harness can be purchased separately if desired.

What is the difference between the Husqvarna 525L and the 525LK?

The primary difference is the shaft design. The 525L features a solid, straight shaft dedicated exclusively to string trimming, whereas the 525LK features a detachable, split shaft. The "K" signifies it is a combi machine, allowing you to remove the trimmer head and click on different attachments like edgers and pole saws.

How do you change attachments on the 525LK split shaft?

Changing attachments on the 525LK is completely tool-less. You simply loosen the knob on the coupler, press the locking button, slide out the current attachment, and slide the new one in until it clicks into place. Finally, tighten the knob to secure it.

How wide is the cutting path on the 525LK?

The Husqvarna 525LK provides a generous 18.1-inch cutting width. This wide cutting path allows you to clear large patches of dense grass and weeds quickly, improving your overall efficiency on the job.

What is Ethanol Free Gas & Where to Find it Near Me

Ethanol fuel, a gas additive, is everywhere! Nowadays, the gas you pump from almost every gas station contains a blend of gasoline and ethanol. The percentage of ethanol blend is indicated by the E number. For example E10 means the gas mixture contains 90% gas and 10% ethanol. In automobiles, ethanol fuel won’t do much harm to your car's engine. However, when you're using gas with ethanol mixture in your outdoor power equipment, like lawn mowers, chainsaws, trimmers and leaf blowers, you run the risk of engine damage and incurring costly repairs. You should be using ethanol free gas in your small engine outdoor power equipment.
