📅 Last updated:
Buying replacement dr string trimmer string sounds simple until you realize that diameter, profile shape, and cut length all affect how well your DR walk-behind mower handles overgrown edges. Too thick and you risk motor strain or poor feed; too thin and the line snaps on fence wire and concrete. Owners consistently report that the difference between a frustrating afternoon and a clean cut comes down to matching the right line specification to their specific DR model and yard conditions.
This roundup compares eight options on published specs, listed prices, and aggregated owner feedback. We focused on diameter, line profile, compatibility, and value per strand. The goal is to help you identify which string actually lasts longer, feeds cleanly, and costs less per use rather than simply picking the cheapest package off the shelf.

We evaluated each product on four criteria: diameter accuracy relative to published DR specifications, line profile (round, twisted, or braided) and its effect on durability, strand count per package for cost-per-use calculation, and owner-reported compatibility with DR walk-behind and 2-wheel mower models. Products that received consistent negative feedback regarding premature snapping or poor feed were noted accordingly.
The 8 Best Dr String Trimmer String in 2026
Kodiake 175 Mil Braided Blue Line
This braided twine is designed specifically for the DR 196601 model and suits owners who want a dedicated match rather than a generic aftermarket line. The braided profile provides a wider cutting surface than round line of the same diameter, which owners report helps with dense grass and light brush.
- Pro: Exact fit for DR 196601, reducing guesswork on compatibility.
- Pro: Braided construction resists shredding better than twisted alternatives at this diameter.
- Con: Higher upfront cost than multi-pack round or twisted options.
Skip this if you own a different DR model that calls for .155-inch line, as the 175 mil diameter may cause feed issues.
BIUVWVZ .155-Inch Round, 25-Inch Pre-Cut, 24 Pack
For owners replacing 38238-spec line on lighter DR mowers, this package offers a straightforward round profile at an accessible price. The 25-inch pre-cut length eliminates the need to measure and cut from a spool, which reduces waste.
- Pro: Lowest round-line cost per strand among the options listed here.
- Pro: Compatible with the common DR 38238 replacement part number.
- Con: Round profile tends to shred faster than twisted or braided on thick vegetation.
Pass if your yard has rocky borders or heavy brush, where round line underperforms.
BIUVWVZ .175-Inch Twisted, 25-Inch Pre-Cut, 24 Pack Blue
The twisted profile here is the middle ground that many DR owners prefer for general-purpose cutting. The .175-inch diameter handles thicker growth without straining the head, and the twist geometry helps the line stay intact on concrete edges.
- Pro: Twisted shape delivers cleaner cuts on weeds up to several inches tall.
- Pro: Blue color improves visibility against dark soil and thatch.
- Con: At $28.99 for 24 strands, per-line cost exceeds the .155 round options.
Not ideal if your DR unit is rated for .155 line only, as the thicker diameter may not feed properly.
BIUVWVZ .175-Inch Twisted, 25-Inch Pre-Cut, 48 Pack
Same specs as the 24-pack above but doubled in quantity. Frequent users who run through line weekly will notice the bulk savings, and the package keeps a meaningful reserve on hand for the season.
- Pro: Lowest per-strand cost among twisted 175 mil options in this group.
- Pro: Eliminates mid-season reordering for average residential lots.
- Con: Higher dollar outlay upfront; not practical for occasional users.
Skip if you trim fewer than three times per season, as storage space and freshness matter less than cost here.
BIUVWVZ 1 Pack 175 Mil Braided with Line Cutter
This single-pack targets owners who want to test braided line before committing to a larger quantity. The included line cutter is a small but useful addition that removes the need for separate cutting tools.
- Pro: Lets you evaluate braided performance on your specific DR model first.
- Pro: Included cutter simplifies trimming to correct length at home.
- Con: Per-strand price is the highest in this roundup.
Not worth it if you have already confirmed braided line suits your equipment; buy in bulk instead.
36 Pcs .155-Inch 38238 Heavy Duty
Thirty-six pre-cut strands at .155 inches make this the highest-count round-line package listed. It matches the DR 38238 part number and suits owners who go through string quickly but prefer the simplicity of round profile.
- Pro: Best strand-per-dollar ratio for round .155 line in this group.
- Pro: Heavy-duty label suggests reinforced polymer, though owners report mixed longevity.
- Con: No twist or braid means faster wear on abrasive surfaces.
Consider a twisted alternative if you frequently edge near concrete or gravel.
24 Pack Universal 38238 Trimmer Line
The cheapest entry point in this roundup at $15.99. It targets DR 38238 users who need a basic functional replacement without premium features.
- Pro: Lowest total package price for a 38238-compatible option.
- Pro: Universal labeling suggests broader DR model fit.
- Con: Fewer owner reviews available to confirm consistency across batches.
Be cautious if your mower demands tight diameter tolerance; verify specs before a bulk purchase.
BIUVWVZ .175-Inch Twisted, 25-Inch Pre-Cut, 24 Pack Black
Functionally identical to the blue 24-pack above, this variant differs only in color. Some owners prefer black for lower visibility on dark mulch and to avoid the blue staining that certain braided lines can cause on light-colored driveways.
- Pro: Same twisted durability profile as the blue version.
- Pro: Black color resists UV fading slightly longer than lighter dyes.
- Con: No practical advantage over blue beyond aesthetic preference.
No reason to prefer one color over the other unless staining or visibility is a specific concern.
Buying Guide
Diameter: Match the Head, Not the Grass
DR walk-behind mowers and trimmers specify a maximum line diameter. Using .175 mil in a head rated for .155 can cause binding, poor feed, or motor overload. Check your owner manual or the sticker on the cutting head. The two diameters in this roundup—.155 and .175—cover most current DR models, but verify before ordering.
Profile Shape: Round, Twisted, or Braided
Round line is cheapest and feeds smoothly but shreds on hard surfaces. Twisted line adds rigidity and a wider cut footprint, lasting longer on mixed terrain. Braided line offers the widest cutting edge and best brush-handling but comes at a premium and may require a head designed for its geometry. Choose based on what you actually cut, not what sounds toughest.
Pre-Cut Length and Pack Size Economics
Twenty-five-inch pre-cut strands remove measurement error and spool waste. When comparing packages, divide total price by strand count to get cost per line. A 48-pack twisted at $49.99 works out to roughly $1.04 per strand, while a 24-pack round at $16.99 is about $0.71. If you cut through lines quickly, bulk twisted often costs less per productive minute than buying round in small quantities repeatedly.
Our Verdict
Top pick: Kodiake 175 Mil Braided Blue Line at $43.40 for owners with a DR 196601 who want a confirmed fit and longer strand life without trial and error. Budget pick: 24 Pack Universal 38238 at $15.99 for occasional trimmers who need a basic round replacement at the lowest entry cost. Condition-based alternative: if you mow heavy brush multiple times per week and run through line quickly, the BIUVWVZ 48-Pack .175 Twisted at $49.99 delivers the lowest per-strand cost among durable profiles in this group.
FAQ
Can I use .175 line in a head rated for .155?
In most cases no. A thicker line increases friction in the feed channel and can overload the head mechanism or stall the motor. Stick to the diameter DR specifies for your model.
Does pre-cut string last longer than spool string?
The material is the same; pre-cut simply saves time and reduces waste from uneven cuts. Longevity depends on diameter, profile, and what you cut, not on whether it came on a spool or pre-measured.
Why does my twisted line snap on concrete edges?
Even heavy-duty twisted line will degrade where it repeatedly strikes hard surfaces. If concrete edges are a chronic problem, a braided profile resists fraying better, or you can adjust your cutting height to avoid direct contact.
Is the line cutter included with the single-pack worth paying extra for?
If you already own wire cutters or a utility knife, no. The cutter is a convenience item that adds minimal value for most buyers, but it is genuinely useful for someone cutting strands for the first time without tools on hand.
