Wow - thanks for this video! It's exactly what I was looking for. Constant hand pain makes changing the bump spool difficult, plus this trim head is more functional than the original one. Works great!

Thanks for putting this up. My bump feeder stopped working today. Watched this, bought the ugly trimmer and installed it without having to rewatch the video. Works like a charm. No more paying 15 dollars per spool....

Worked for my Kobalt 24v 12" trimmer (Model #KST 2224B-03). I purchased an inexpensive set of 4 black 4" silicone coasters to put 1 between the trimmer head and the original black metal ring to add protection to the motor parts. Punched a small screwdriver hole in the coaster and pushed it down onto the black ring. The silicone will keep it tight on the motor bolt as long as you don't make the hole too large. Other variations of part positioning failed and some kept the motor from spinning. Following the information for the stacking order (plus putting the coaster on before the new trimmer head) worked great. The accessory attachment model 15" (designed like it 'could' adapt more easily to attach after marker trimmer heads) version is 15lbs. This model is 5lbs. My light weight trimmer has been given new life and function. Thanks for posting the video.

I reused the spinning base of the trimmer which protects the motor. It's the part on the left side in the video at 4:04. I bent the 4 tabs out until the base of the new trimmer unit can be pressed down around the shaft. The shaft was long enough to then screw the new cutting head onto it. You have to carefully screw the new unit on since the four tabs will be springing back into place. But I bent them until they stayed open enuogh for me to press the new trimmer head down and screw it into place. The four tabs help center the new trimmer head. I did this for a 24 volt Kobalt trimmer. It works great and the motor is protected.

Your video saved me from tossing out the Kobalt 24 volt string trimmer for a different brand one that took universal heads. Loved how you walked us thru using the included special bolts to retrofit a 24v big head with the Shakespeare Ugly Head 2 in 1 universal trimmer head. THANK YOU

Thank you so very much kind sir! This is perhaps the most thorough as well as useful video I've ever watched on KZfaq! And at 57, I've watched thousands upon thousands. I can't adequately express my appreciation, so I'm leaving you a ❤

You just made my life a lot better! Thanks for posting. Works great!

Thank you for posting this and being so detailed. I was going to return my trimmer and purchase a different model since the auto feed doesn't work for me but instead I will just try this first.

I got a Echo Speed Feed 400 to work on my 24-volt Kobalt. I used the black insert and the original nut to attach it. I have been using mine for 2 seasons now. Thanks for the video!

Great video and explanation!!! I have the 40v and this video worked for that model as well. Thank you!

You are a life saver for this, cant wait to get one, that bump system is a pain in the ass!

❤wow amazing..you are helping so many people like myself. .kudos

Awesome, I'll be giving this an attempt this weekend

It works great!! Did it on mine thank you :) i bought my ugly head trimmer head at Lowes

Thank you I'm putting a Shakespeare head on and needed to see how to get the bolt off. Thank you.

oh this is great. i had just one more question though if you don't mind? as far as the original "bump" head before you modified it, does the trimmer have to be RUNNING for the bump to work and feed more string? or can it also be done if i "bump" it when it's off to see the line length to where i want it?

I like the Shakespeare push and load head and love it. Installed it easily on my gas trimmer and recently got this Kobalt so got another head for it Installs the same way as the one you had and was quick and simple. I'm ready to go for Spring.

Nice video thanks for the help

I can’t get the nut to budge even with the new metric tool. How in the world did you get it off? The head keeps spinning and I can’t get a grip on it?

Got mine for 25 dls lightly used and is a beast…I already have kobalt tools so have plenty of batteries including an 8 ah one and it last for over an hour.

This video was super on point today...I have been looking to dump a bump feed since I bought mine...Install was exactly as detailed...One footnote- If you run .095 line or wire all the time I am sure you will have motor heat overload with pauses in your work...Mine did that with just two work lines of 105 line...So when I installed today i used .80 line and I still got it to overheat pause when working it hard...think about it bcuz your spinning 6 lines instead of 2...FYI MAC

How have you guys loosened that reverse nut attached to the motor? My original locking nut is on there something fierce and I don't have any leverage to try and twist it off. I even opened the rear panel to the motor flywheel but there really is no good place to clamp onto to hold everything still while trying to back off that nut.

Outstanding

Thank you for the great video! One question, and forgive me if it's a noob one, but since you just twist on the new head and don't have a nut to secure it, is there any chance the head can loosen and fly off?

I burned up two trimmers doing this one was an 80v the other was a 40v. These heads are made for gas trimmers

man... that was exactly what i was lookin for... thank u! ...& quick question please, the nylon blades on the shakespeare, are they to "aggressive" (ie; would they damage?) a plastic fence? ...i have a white fence around my property that looks like a wood fence but its actually some sorta plastic?/pvc?/poly? of some sort... im thinkin the string might be safer, but was just currious what u thought having used them...? thank u sir

Hi there. Thanks so much for you video. Is it the case that when you start to disassemble the original head, you just push down on the center part and turn it to remove it? I am unable to remove the center part, but perhaps I just need to be more forceful. Thanks!

Thank you. For the 40v, none of the nuts worked for me. You will need to get a M10 -1.25 JIS nut so that it fits the thread AND down into the brush head . . . 😅 something I didn't want to learn about but nonetheless, it fits perfectly. I have extras since I had to buy a box of 'em online. Couldn't find the JIS nut in hardware or auto stores.

I need the inner reel spring

I made this conversion, however, I'm having a lot of issues with the line breaking off down to a nub after just 5 or so minutes or relatively light use. I tried the original line (.095) and their professional grade line. Both still having that issue. Anyone else encountering this and find a solution?

I'd be afraid the open motor air holes will "suck up" some grass, especially wet grass and cause the 24vt motor to short out.

You saved me from buying another trimmer Ty

I just did this to my trimmer, and I left the cooling disc on. I noticed when I use the blades it continues to run, but if I put the strings in it spins pretty fast and the motor shuts down. I'm not sure if that's a safety feature or what.

I have the same 24-volt brushless string timmer from Kobalt. The one that uses the .080 string. I noticed in the video that this Shakespeare head allows you to use .095 string. Is this string good to use when trimming against a chain link fence? The .080 string seems to be deteriorating pretty fast when I trim around my chain link fence. It is quite annoying 🤬🤬

Hello. Having issue with my conversion. The string keeps getting cut. It will trim maybe about 10 feet and the it’s down to the nub.

Followed instructions to the T, no vibration, on there right in the middle, when I use Blades its fine and will blast through anything, but when i use the lines instead of blades, it just keeps shutting down as soon as it touches the grass... will run with lines just holding cutting end in the air, but as soon as it touches grass it shuts down 😞

Wanted to see how you got the bolt off, you completely skipped that part.

Any idea what size the spring is that comes in original set up?

Does this work on 80 volt?

I have the same setup but after i replaced the head, the trimmer shuts off when i get into slightly thicker grass. So far i havent found or solved the issue. Any clues?? I dont really want to go get another weed trimmer as a replacement.

I replaced the head on my kobalt 24v and unfortunately this did not work. I’m 63 and work my 1/2 acre on my own and I thought this would be my answer to making the yard work easier. At first the weeder would work for a few seconds and then die. Once the line got shorter it did great but it got hot and then went back to working for a few seconds and then nothing. I just removed the battery and I’m letting cool but I’m replacing the original head here soon. Like he said do it at your risk and good luck. The video was pretty easy to follow and it would have great if it worked for me.

You seem to be very knowledgeable however mine is a 14 inch cut(same kobalt trimmer otherwise) would this work??

Would have been nice to have an update after a year and two.

How you took the screw nut off !! Because it turn while you trying to loose the nut

How do i get the piece off the kobalt to change the attachment head??

Motor burn up yet? I did something similar (covered the holes with tape for trial run) to my atlas 80v and noticed the motor is much more prone to shutting off now

Have you done a black and decker?

How did you took apart the old head?

Did you notice a difference in the run time? How long does the pre-cut line typically last?

Do you think it will work for the 40v trimmer as well?

How does it do as an edger?

is yours still running well?

Do you think this model trimmer is powerful enough to run a metal mulcher blade? Basically a 12 inch piece of rectangular steel

Hey, might you be willing to sell the original head from your 24v Kobalt weed eater?

You talk too much! Just get to the point!
