Frequently asked questions

What fuel mixture does the Husqvarna 122LX require?

The Husqvarna 122LX is powered by a 2-stroke engine and requires a 50:1 gas-to-oil mixture. For optimal performance and engine longevity, use high-quality unleaded gasoline (minimum 89 octane) mixed with Husqvarna 2-stroke oil. Alternatively, using pre-mixed, ethanol-free fuel can help prevent carburetor issues. To find our convenient pre-mixed fuel, visit: https://www.husqvarna.com/us/fuel-oil-lubricants/2-stroke-fuel-and-oil/ 

How do you replace the string on the Husqvarna 122LX?

Reloading the line on the 122LX is fast and simple thanks to the RapidReplace trimmer head. You align the arrows on the trimmer head, feed the replacement line directly through, and twist the bump knob to wind it in. There is no need to disassemble the head. If you want to watch a short video, visit: https://www.youtube.com/watch?v=3KWZnaNhELw&t=15s

What size trimmer line does the Husqvarna 122LX use?

The Husqvarna 122LX RapidReplace™ head is optimized for standard 0.080-inch or 0.095-inch trimmer line. Using the manufacturer-recommended line thickness ensures smooth auto-feed operation and the best cutting performance for residential lawns.

Is the Husqvarna 122LX attachment capable?

No, the Husqvarna 122LX is a dedicated straight-shaft string trimmer and is not designed to accept interchangeable combi-attachments like pole saws, edgers, or sweepers. If you need a multi-task tool, consider exploring Husqvarna’s line of Combi Trimmers.

How much does the Husqvarna 122LX weigh?

The Husqvarna 122LX is designed for comfortable residential use and weighs just 10.14 lbs (excluding cutting equipment). Combined with its ergonomic, soft-touch grip handle, the lightweight design significantly reduces user fatigue during extended yard work.

What is the difference between a straight shaft and a curved shaft trimmer?

The Husqvarna 122LX features a straight shaft, which provides an extended reach—making it ideal for trimming under bushes, decks, or along fences. Straight shafts are also generally more comfortable for taller users. Curved shaft trimmers (like the Husqvarna 122C) are typically more compact and easier to maneuver in tight spaces.

Is the Husqvarna 122LX suitable for commercial landscaping?

The Husqvarna 122LX is purpose-built for homeowners and residential yard maintenance. While it features premium innovations like Smart Start® and RapidReplace™, professional landscapers requiring a trimmer for daily, heavy-duty clearing should consider Husqvarna’s professional-grade 500-series trimmers.

What does the Smart Start® feature do on the 122LX?

Husqvarna's Smart Start® technology is engineered to make starting the 122LX fast and effortless. The specially designed engine and starter reduce resistance in the starter cord. When paired with the built-in air purge system, it ensures reliable starts with minimal pulling.

Is the Husqvarna 122LX a 2-stroke or 4-stroke trimmer?

The Husqvarna 122LX is equipped with a lightweight, 21.7cc 2-stroke engine that delivers 0.8 horsepower. Because it is a 2-stroke model, it requires a pre-mixed blend of gasoline and 2-cycle engine oil to operate.

What is the cutting width of the Husqvarna 122LX?

The 122LX offers a generous 17-inch cutting width. This wide cutting path allows you to clear large swaths of grass and weeds quickly, reducing the time it takes to edge and trim your property.

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.
