When it comes to selecting the right trimmer line for your Homelite string trimmer, there are a few key factors to consider: the thickness or diameter of the line, the shape of the line, and the material it’s made from. By understanding these aspects, you can choose the ideal trimmer line that will provide the best cutting performance and durability for your specific Homelite model.

Line Diameter
The most important factor in choosing trimmer line is the thickness or diameter. Homelite trimmers are designed to work with a limited range of line diameters, usually from 0.065” to 0.155”. Using a line that is too thin or too thick can lead to poor performance and potential damage, so always consult your owner’s manual to confirm the right size.
Here are some general guidelines on trimmer line diameters for Homelite units:
- Light duty trimmers: 0.065” – 0.085”
- Standard duty trimmers: 0.095″ – 0.105”
- Heavy duty trimmers: 0.110” – 0.155”
Light duty trimmers are lower powered models designed for basic lawn edging and occasional trimming. Standard models can handle frequent mowing and moderate vegetation. Heavy duty units are high torque models built for large properties and cutting dense brush. Matching the line diameter to your trimmer’s power output and intended use will optimize cutting efficiency.
Line Shape
In addition to diameter, the shape of the trimmer line also impacts performance. Most standard Homelite trimmer lines utilize a round or twisted shape. Here are the benefits of each:
- Round: The most common style, round lines offer smooth cutting and are less prone to breaking. They work well for light to medium trimming tasks.
- Twisted: These lines have a barbed, twisted profile to slice rapidly through thicker vegetation. They provide more power but are noisier and wear faster than round lines.
Specialized shapes like square, multi-sided and serrated are also available for specialized cutting, but are not widely used on standard Homelite consumer models. Always check manufacturer guidelines as specialty shapes may damage some trimmers.
Line Materials
Homelite trimmer lines are produced from two primary materials:
- Nylon: The most common choice, nylon monofilament is durable, flexible and inexpensive. It works well across a variety of conditions.
- Polymer blends: Some lines incorporate polymers like polyester for added stiffness and improved cutting, albeit at a small cost premium. These enhanced materials are best for thick vegetation.
You may also find older Homelite trimmers that specify using metal-reinforced lines. However, most models produced in the last 15-20 years utilize standard nylon or polymer lines. Always check any special material requirements in your owner’s manual.
Optimal Trimmer Line Selection
Taking all these factors into account, here are some specifics on choosing the ideal trimmer line for popular Homelite models:
| Homelite Trimmer Model | Recommended Line Size | Recommended Line Type |
|---|---|---|
| UT33600 | 0.065″ diameter | Round nylon line |
| UT33650 | 0.080″ diameter | Round nylon line |
| UT33620 | 0.095” diameter | Twisted nylon line |
| UT33120 | 0.105” diameter | Twisted polymer line |
| UT33600Z | 0.155” diameter | Twisted nylon line |
This covers a range of light, standard and heavy duty Homelite trimmers. Always defer to your specific owner’s manual if there are any discrepancies. Additionally, inspect and replace the line regularly as frayed or worn line will reduce cutting effectiveness.
Where to Buy Replacement Trimmer Line
Once you know the optimal diameter and type of line for your Homelite trimmer, there are several options for purchasing replacement spools:
- Check local home improvement stores like Home Depot, Lowe’s or Ace Hardware for inventory of common trimmer line sizes.
- Visit your local authorized Homelite dealer or small engine repair shop.
- Check online retailers like Amazon, Walmart or eBay for discounted multi-packs.
- Purchase directly from the Homelite website or other authorized online dealers.
Be sure to closely inspect any third party replacement line for the correct specifications. Using improperly sized or lower quality line could lead to decreased performance or place undue wear on your trimmer.
Loading the Trimmer Line
Once you have the new trimmer line, loading it into your Homelite unit is a quick process:
- Refer to your owner’s manual for the proper spool removal technique for your model. Usually there is a spool cover that can be taken off with no tools.
- Clean any dirt buildup from the spool and trimmer head area.
- Take roughly 5-6 feet of new trimmer line and insert the end through the anchor hole in the spool hub.
- Wind the line evenly and snugly around the spool in the direction specified in the manual.
- Leave about 6 inches of free line and then insert the end through the exit eyelet opposite the anchor.
- Replace the spool cover and turn the trimmer head to align the lines.
- Check line length and evenness, trimming any excess length at the eyelets.
With the new line loaded, your Homelite trimmer should be ready for optimal cutting action. Always take safety precautions and wear protective eyewear when operating power trimmers.

Conclusion
Choosing the best trimmer line for your Homelite string trimmer requires matching the diameter, shape and material to your specific model’s requirements. Round nylon lines in the factory recommended size provide a good general purpose option. Check your owner’s manual for guidance and properly load the new line onto the spool. With quality line installed, your Homelite tool will be back to full cutting power.
