How to replace line on Craftsman gas trimmer?
On the Craftsman CMXGTAMDSS25 gas line trimmer, replacing trimmer line is usually a quick spool reload: you feed new line through the cutting head eyelets, wind it evenly (no overlaps), then reassemble so the line can advance smoothly when you bump the head.
- Shut the engine off and let the muffler cool completely.
- Disconnect the spark plug boot so the trimmer cannot start accidentally.
- Wear gloves and eye protection; trimmer line ends can whip and cut.
- Clean grass and debris off the head so the line seats correctly.
- Remove the spool cap (most caps twist off; some use tabs).
- Pull the spool out and remove old line pieces.
- Cut two equal lengths of new line (use the diameter recommended for your head; if the line is too thick it can jam).
- Feed one line end through each eyelet, then seat the line in the spool channels.
- Wind the line in the direction shown on the spool (keep wraps tight and side-by-side, not overlapping).
- Leave a short tail on each side, reinstall the spool and cap, then pull both tails to release them from the retaining notches.
- Line is crossed or overlapped on the spool
- Wrong line diameter for the head
- Spool wound in the wrong direction
- Debris packed inside the head
If the line will not feed after a correct reload, the head components may be worn or damaged. For this model, the compatible assembly is the mtd line trimmer cutting head 841P035132S.
| Symptom | Most likely cause | What we recommend |
|---|---|---|
| Line will not advance | Line jammed, wrong size, dirty head | Rewind correctly; clean head |
| Line advances but breaks fast | Line too thin, hitting hard edges | Use correct diameter; avoid edging on concrete |
| Cap will not stay on | Worn cap tabs or head damage | Inspect head; replace if needed |
A properly wound spool (tight, even wraps with no overlap) reduces tangles, improves bump-feed performance, and helps the CMXGTAMDSS25 cut consistently without constant stops.

Which is better, .080 or .095 trimmer line?
For the Craftsman CMXGTAMDSS25 gas line trimmer, .095-inch line is usually the better all-around choice because it holds up longer in heavy weeds and along fences. .080-inch line can cut well too, but it typically breaks and wears faster, so you reload more often.
- Choose .095 for thicker weeds, edging near hard surfaces, and longer runtime between reloads.
- Choose .080 for lighter trimming, delicate areas, and slightly easier line feed.
- If your trimmer head or spool is labeled with a maximum line diameter, do not exceed it.
- If you notice frequent line breakage, step up in diameter (if your head supports it).
- If the engine bogs down in dense grass, a slightly smaller line can reduce load.
| Feature | .080 line | .095 line |
|---|---|---|
| Durability | Lower | Higher |
| Best for | Light grass, touch-up trimming | Heavy grass, weeds, fence lines |
| Reload frequency | More often | Less often |
| Cutting aggressiveness | Moderate | Higher |
On the CMXGTAMDSS25, the deciding factor is often the cutting head design and what it is built to feed reliably. If the head is worn, cracked, or the eyelets are damaged, even good line can snap or jam. If you are troubleshooting feed issues or replacing the head, use the model-matched mtd line trimmer cutting head 841P035132S.
Using the right line diameter helps your Craftsman trimmer cut efficiently, reduces frustration from constant breakage, and can prevent premature wear on the cutting head and spool.

How do I find the model number on my CMXGTAMDSS25?
The model number for your Craftsman ws2200 gas weedwacker is printed on the product ID label; on CMXGTAMDSS25 trimmers, that label is typically on the shaft (boom) near the engine, handle, or debris guard. Match the full model number exactly before ordering parts.
Check these common label locations first:
- On the shaft/boom near the engine housing
- Near the throttle handle or handlebar clamp area
- On the underside or back of the debris guard
- On the engine housing near the recoil starter
- Near the fuel tank area
Most Craftsman trimmer labels include a model number and sometimes a serial number. For parts lookup, we use the model number.
| Label item | What it’s used for | Example |
|---|---|---|
| Model number | Identifies the exact parts list and diagrams | CMXGTAMDSS25 |
| Serial number | Production tracking; not usually needed for parts | Varies |
Model numbers can be close, so copy it exactly (including letters and dashes).
- Clean the label with a damp cloth so every character is readable
- Take a clear photo before the label wears further
- Use the model number to confirm fit before buying common tune-up parts
- If your trimmer won’t start, confirm the model before replacing ignition or fuel parts
Craftsman trimmers often share similar frames but use different carburetors, cutting heads, and ignition modules. Using the exact CMXGTAMDSS25 model number helps you get the correct diagrams and the right replacement parts the first time.
If you’re doing a basic tune-up after confirming the model, common items include the line trimmer spark plug 753-06847 and the mtd line trimmer air filter 753-06417.
