Ratings & Reviews for Kobalt QUIET TECH 24-volt 15-in Straight Shaft Battery String Trimmer 4 Ah (Battery Included) (Charger Included)

Forget about reloading the twine

Engineers love to go with theory rather than practicability. If anyone has found a way to reload the twine with their new system, I’d love to hear it. The twine will immediately jam and won’t hold tension because of the way you need to wind it, can’t even do it manually because the clips get in the way. Avoid this new design at all costs. (Also, all I own is Kobalt lawn equipment. It’s that bad.)

ITEM #7217306 MODEL #KST 2024B-03 STRING TRIMMER

My string trimmer plastic spool cap needs to be replaced. I cannot find the exact part for this model. Does anyone know where I can find this replacement piece?

no replacement head

This trimmer worked for awhile, although the bump feature was a joke. Line would not extend. Took it apart, removed the old line, put in new line (what fun), snapped it together. Again it worked for awhile, then I only had one line and couldn't get the other one to work. Plus it was heavy for 79 yr. old.

Garbage

Avoid this brand it’s extremely difficult to replace the trimmer line so basically it’s garbage

Slightly better string replacement theory

Out of the box, the string fed once, then seemed to be getting stuck together. Tried disassembling the head and feeding manually, but this didn’t work any better and the whole head contraption flew apart. The manual is useless as the directions ended up with the original factory provided string protruding from the spool on only one side. Time to find the receipt for a refund.

Kolbalt Weeder

L9ved it really powerful,cuts the edges really deep and doesn't make a lot of noise like other brands I used to have.

impossible to reload

this trimmer is fine until you need more line. I had to take the cap off multiple times, then the lines came unraveled and i have spent the last hour getting eaten by mosquitos trying to get the line fed correctly. the manual is trash and only talks about the battery.

Starts and Stops

Bought this less than 3 months ago. Went to use it last week and it will start and immediately turn off. It is not the battery because I have a Kobalt blower and it works fine in it.

Works great but

Really like it. It’s my third one over last 10 years. I upgraded to this one due to the bump head being for me easier to load. However, third time I used it the bump head cracked. Bought in May 2026. Guess I’ll File a claim under 5 year warranty for replacement. .

String jammer

Seems impossible to reload string without jamming issues

To reload string is horrible.

Last kobalt 24 volt trimmer lasted about 5 years then won’t run. Looks like new just dead can’t get parts. Purchased a new 24 volt it’s the same other than the trimmer head. It’s impossible to reload the string by turning the knob. Finally took off and reloaded manually like old style. Took a few times off and on to get it to advance line. Trimmer is fine but the trimmer head is junk.
