Is your string trimmer struggling to cut through thick weeds? I know the frustration of using those flimsy plastic lines that snap every five minutes when you hit a patch of tough grass.
I decided to try out these 150mm metal trimmer blades to see if they could handle my overgrown backyard. This 1/5PCS 150mm Metal Grass String Trimmer Head Blade Replacement Lawn Mower Saw Blades Fittings Garden Power Tool Accessoris review covers exactly how these hold up against real yard work.
What are these metal trimmer blades?
These are basically circular saw attachments designed to replace the standard bump-feed head on most weed eaters. They come in a simple metal disc shape with teeth that act like a tiny chainsaw for your lawn.
The main appeal here is that they are extremely budget-friendly compared to name-brand mower parts. I found these online with free shipping, which made them a very cheap experiment for my lawn care kit.
Real world performance and features
The biggest benefit is that these blades do not snap or wear down like plastic string. When I hit a thick woody weed or a stubborn stalk, the metal blade cuts right through it instead of fraying or breaking.
Installation was pretty standard for most straight-shaft trimmers, though you need to make sure your machine has the right mounting hardware. Once it is on, the cutting path feels much more aggressive and efficient than using string.
Honest pros and cons
- Pros
- Much cheaper than buying rolls of high-end trimmer line.
- Cuts through thick stalks and woody brush that string cannot handle.
- The metal build lasts through many more hours of work than nylon.
- Free shipping options make this an easy low-risk purchase.
- Cons
- Shipping takes a long time since these come from overseas.
- If you hit a rock or a metal fence post, the blade can chip or kick back.
- The learning curve for installation is steeper than just winding a new spool.
- Not all trimmers have the power to spin these blades safely.
Who should use these blades?
If you have a large property with tall weeds, heavy brush, or thick grass that kills your string, these are a great upgrade. People who want to save money on expensive replacement line refills will definitely appreciate the value here.
You should probably skip these if you only have a small, manicured lawn with light grass. Also, if your trimmer is a smaller electric model, it might not have the torque to spin a metal blade effectively without overheating the motor.
What other buyers are saying
I checked in with a few others who grabbed these to see if my experience was typical. One neighbor mentioned he used them to clear a patch of blackberry bushes and was surprised they held an edge for so long.
Another user pointed out that while the blades are cheap, you need to be careful about safety. Everyone seems to agree that you should definitely wear eye protection and long pants since these blades throw debris much further than plastic string.
Final verdict
After using these for a few weekends, I think they are a solid tool for the right job. You get a lot of utility for a very small price, and the metal construction is a massive improvement over standard string for heavy-duty clearing.
Just keep your expectations realistic about the shipping time and make sure your trimmer is built to handle an attachment like this. If you are tired of constant trips to the store for more plastic line, this 1/5PCS 150mm Metal Grass String Trimmer Head Blade Replacement Lawn Mower Saw Blades Fittings Garden Power Tool Accessoris review concludes that these are worth a spot in your garage.
