You just saved me $300 bucks. I did it and it actually worked! I did the whole yard and even cut small trees!

Ok i’m Back from doing this to my 60v Dewalt trimmer. Holy F. This is one beast of a machine. No more buying string, failure to feeds, finding broken neon string particles in the yard etc. Plenty of clearance on the 60v Flexvolt trimmer to keep the guard on so did it in fewer steps. Ended up using the washer off the skill saw to get the right height. Saved me from having to rent a tool for a few acres of Florida brush cutting. Dewalt makes no attachments but this mod makes up for that. I was wearing a face shield but found this MUCH less apt to fling debris my direction than the string. Also, kick back on this thing is very controllable. I was cutting through heavy patches of 1” elderberry trees like it was St. Augustine grass. You will want to really tighten the screws on the shaft of this tool. All in all it is very workable. Thanks again man for the idea. It works great.

"This looks perfectly safe. I don't see anything remotely dangerous about that" 😄

I've used this setup (and many similar) for about 20 years on various weed eaters. Never did like string as that is mainly for home grass trimming. Not really *weeds* or thicker stuff. I have used the saw blade and the disc with chainsaw blade around outer edge on one machine for this sapling areas. Then another machine has a universal attachment (Weed Wizard) with about 4 inches of what closely resembles bicycle chain. I recently picked up a 20v DeWalt weed eater closest I came in my searches is the BadgerHead or Grassgator. I still do love the saw blade attachment for saplings. Definitely make sure you are using a properly fit blade or make/buy a plug to center the blade. Had one that I didn't center properly one time and the imbalance was a nightmare.

I made mine about 1 year ago too. I just made myself a centering washer for the blade and I just left the guard on to protect your feet if it kicks back. Best trail making device on earth !! Our bike club has over 40KM of trails and we use this to create and maintain all of our trails !! We also use the Milwaukee Pruning M12 saws. It's the lightest and best 3 to 4 inch branch/tree cutting device.

"But never under any circumstances should you ever run a weed eater with no guard on it." *Proceeds to remove guard*

This is the exact model of trimmer I am trying to do the same thing. Thanks for showing how you did it.

I just put a washer under the blade and it easily clears the guard. No need to take off the guard. And yes, I am all for a little risk but take the battery out when working on it, it's too easy for a totally preventable accident when you leave it in.

i just bought one of these at the end of last year - only got to use it once before the snow came but glad to see this works with a saw blade - have roughly 50 katrillion skillion bajillion aspen saplings that need removing - did what seemed like the same amount over the past few years with a combination of a pole pruner for the small ones, recip saw for the slightly bigger ones and the pruning saw for the big ones.

That is a zombie killing machine if I have ever seen one...nice work!

Nice. I want to try this with my electric trimmer. Looks like you saved yourself both the bother and the cost of buying a brush cutter attachment.

Sound just like my dad!!! 😂 and now me!! Let's try it!

Beautiful Custom Mod Right there! This is how I need to roll out on my Granny's Rental Farm about 5 miles outside of downtown Muskogee. You had me snorting with laughter all thru your cool demonstrations and Mod Work: 0:59 *Crocodile* *Dundee* - _"That's Australian for a Nylon String Weed Whacker, Mate!"_ 5:55 - _"..Looks perfectly safe!"_ - Had a nice vision of *Wyle* *E.* *Coyote* going after *The* *Roadrunner* by standing on a thin cliff ledge with a big heavy duty *ACME* Weight.

I ran across this video looking for a brush cutting blade for my DeWalt battery trimmer Model DCST990 which I have had for 13 years. I don't believe DeWalt made a brush attachment so looks like I'll be converting mine over like you did. Thanks for the last part about cutting grass as I wondered how the blade did on very thin stuff.

I was looking for this video, if 20V trimmer can handle a blade. But I will order adapter kit and a 8inch light weight brush saw from amazon. Thanks for sharing

Also, it would cut a lot better if you didn't have the blade in backwards. I have the same trimmer and I am sure.

Best thing ive seen all day.my days are filled with awesomeness.thank you for making this sir

there are many saw blades with round / (knock out holes that have the Dimond shape ) the right size washer on the thread side( inside diameter ) thinner than the blade would center the blade or drilling the blade to the size size washer you can find thinner than the blade

When you start messing around with that blade, you should remove the battery. You basically got a handheld table saw, lol. Also, would smaller teeth work better? You could also try using a thin kerf blade. I think the thin kerf would give it more speed and make the battery last longer. You could also make the blade smaller for more speed and power.

Couldn't wait until tomorrow, Holy crap works great ...thanks

Nice work Luke... maybe you could figure a simple gaurd mounting it in the rear bolt holes from the head where you removed that cover ? Would not need to be much, like u shaped bit that would redirect or slow the blade, made out of a piece of coathanger or something, mostly just to keep the blade from coming right back at you.

My wife said "And now we know why women live longer than men." 🤣

I would totally use that in the zombie apocalypse

That is Awesome! I always thought there was a way to bi-pass the string approach.. Manufacturers get u to continue to buy the string & there must be a better way than that! Luke ...perhaps u may want to make a guard out of steel to guard urself..if even for some reason the nut ever got loose and the blade came off it could not hit u.. just a thought 💭.. I try to be as Careful as I can.. looking out for u Buddy ✌🏼👋🏼👍🏼😁🙏🏼

Awesome ....rhanks for the video . Going to do the same to mine . I jave a lot of suemak to take down .

Always remember; Safety third! :)... Great improvisation... Looks like she does the job...Brush is a PAIN IN THE ASS to keep up with...

You should make something that fits on that diamond shaped hole and on the trimmer shaft.

Good show. Thanks!

Great mod Luke! I wonder if that could be useful for trimming low hanging branches in your trees, and also as a hedge trimmer. It would probably make short work of those. Also, maybe it could be mounted somehow and the trigger controlled with your foot to use as a cut off or table saw.

Great since of humor. AND a useful mod. Thanks.

2:50 "Never under any circumstances should you ever run a weed eater with no guard on it.... so lets take this guard off."

"Look mum, new brush cutter"...."look mum, no legs" like all good toys - deadly

Ok I’m back yet again and had a malfunction that people are probably very concerned about with this mod and good news is that it was not bad at all. Had the blade come loose and it spun off very weak no big deal. Also skill saw blade got dull after two long sessions, each session going through 5 - 9ah 60v batteries and spinning though countless dirt covered 1” thick woody stems like they weren’t s####. Taking all that into consideration, this is still freaking awesome.

I used a new 5 1/2 inch blade it has the round hole same size as the bolt, and modified a second guard I had for a Craftsman gas trimmer with the shaft that disconnects for attachments ( I have extra parts from a old trimmer that broke), better than the $85 they want for the attachment.

You ever do any arm wrestling? You've got some girth to those forearms.

dude, love it. Just what the Dr ordered.

It's not clear what that pin was and where you got the washer? Can u pls explain? They do sell $10 adaptors for this and the forester has a circular chainsaw blade for this exact purpose.

Dammit man! I want to do this to my Dewalt now!

I think the power tool manufacturer should make them motors to stop instantly when you let go off the trigger instead of coasting to a stop; BTW, that rigging worked fine; Recently, just recently I bought a kit to properly attach a saw-blade to a trimmer but have not installed it.

Did you know you can buy reducing ring bushes for circular saw blades, no more centering when you go to hard!

I'm thinking I want to do the same maybe with a pie tin and some of one side edge and bottom trimmed off. Was thinking freezing a rubber ball to drill out smaller than the nut head so real tight fit when soft or something maybe plastic or metal with some silicon/starch in a hole in the middle to shape tight around the nut wrapped in saran wrap. Probable can even make a custom machined nut tip also might be better at the community college or library if they have the 3D printers since seems is more common I've been seeing. I was thinking like a wood center or I guess 3D printed can be done too for a guide to make sure the blade is always centered. Probably easy enough to just make a blade adapter aligner out of scrap aluminum, brass or some smashed copper pipe even thinking too with just a drill, hacksaw and file for a tighter fit.

Looking to make a edger so thanks for the hard core test lol I'd suggest sheliding with Thick gage sheetmetal exposing 25% only all around it . You should put it on a durable extension pole for tree trimming done it with gas never 20 volt dc. I'd caution everyone without real fabricating expierence.

Looks great.... it looked like the blade was running backwards according to the teeth? or was it a trick from the camera?

Whoa that new DIY gadget looks like a George hazard! Be careful with it, bud! Maybe that's your scariest gadget yet! lol

Haha.... Stumbled onto this and had to subscribe. Great humor!.... BTW. I. Am. Waiting for a renegade 80t as I type this.

Great vid.

country boys can survive!!!!!!!!!!!

Im on the hunt for the adapter in the us witch doesn't offer it. And nobody ships it overseas Dt20657 . If anyone has a idea where to get one please help.

Well done! I'd probably invest in a suit of armor to wear when i was using it though. :)

Did you put the blade on the wrong way??? And how the heck does that blade not take off the nut with the direction it's spinning from the torque?

Good evening, Good you help me with what size nut you used to tighten the blade on with?? I am having trouble finding one. Great video and thanks

What sort of fit would you have on the standard round arbor blade without punching out the diamond divot? Surely wouldn't be lucky enough for the arbor to be smaller, would it? That would be ideal if you could worry with enlarging the hole, because I'm sure that there's no way in hell that it would default to the 'proper' size. If it's larger I'd bet it wouldn't be hard to find (and/or fit) a washer to eat up (fill in, that is) that space between the shaft and hole. No matter what, a round hole is far preferable to that diamond hole...which is gonna be real, REAL noticeable, and FAST, if/when it slides out of round and the blade shears/slings toward some extreme in that diamond hole! I wonder if the reason DeWalt and/or third party/after market parts and accessories suppliers shy off of blade attachments for these things is related to some inherent inability for the little electric motors to meet the demands that blades produce....and if so, is it that they are confident that the motors can't or is it because they aren't willing to take chances on having to recall a really, really cost prohibitive chunk of change ... and that's being 'lucky' enough that tort lawyers don't get involve (which is about as likely as a big chunk of shit drawing zero flies, an example that's quite apt if you think about it). I'd bet on it being that they aren't comfortable doing it, even though I'm sure there are tons of tweaks that would help support the use, from blade size, thickness, weight, etc. to varying the kerf of the cut.

Good, I’ll do the same thing with my electric trimmer!

Dude you are a genius!!

Love It! "The best part, zero dollars."

entertaining and helpful .... good stuff

I tried this but it just unbalances so quickly. I'm surprised there's no conversion kit

Lol....IDK if a lockwasher would help or not....anything to make it safer if you are gonna use it that way....you are a brave fellow!!!!

Do you still do this? I'm curious how well it's worked out for you.

Efficient to have creek and road in same space.

Thank you brother!!!

There is a slot to stick a screwdriver into to hold the shaft while you tighten it.

Was the blade facing the right way

You put it on backwards to start with ;)

good job but be careful ,i am your fans ,god bless you

Hit it with spray paint.so its easy to locate the center again

What is the shaft diameter ?

Did you flip the blade over because it was spinning in the wrong direction.

Would this work on the 60v?

Thats very cool! Dont listen to these other guys freaking out that its too dangerous. They should just wrap themselves in bubble wrap and sit in a room! Stay hillbilly!

tack weld your washer on to your saw blade, then it should stay balanced

You need a safety shield and a hard hat gloves 🧤 that is very important

Can I do this with a Black and Decker or Craftsman electric trimmer?

Hero.

Hey bud how is this holding up so far? Been thinking about doing this to mine!

Here's a review of other blade ideas to consider: kzfaq.info/get/bejne/frx6rZp41tTDg40.html

It makes me nervous to see you balancing that blade with the battery still on the tool.

okay, riddle me this, just got a blade and a harness (safety first!)so want to play with it.... but how the #$%^& do you get the spool out??? the top cover comes off, but the spool is stuck in the thing... and i can't get the thing off to the other thing off to put the new thing on...

It looks like the saw blade is spinning the wrong direction for the way the blade is turned.

Looks like you made a pole saw

Thanks man

what are the chances you could do a vid on how to get the $%^&UI bottom string spinny bits off? i don't want to bugger mine up, and if it's too difficult i may just suck it up and buy another one so i don't have to keep changing it out.

Clicks trigger 5seconds conclusion : yep that’ll work 🤦‍♂️ lol lets get to swinging the limb looper ....yep ya see how easily it cut the branch well I’m guessing about as easy as it’d cut a meat branch off good luck sir

Ohhhh my god. This is crazy. Do you still have all your legs ?

Looks like your blade is on backwards

OMG Luke! Great Idea but I certainly hope you either get a spacer or a proper weedeater blade and maybe some kind of lockwasher to increase the safety factor! That thing is scary even for an 18 or 20 volt battery operated thing! That thing even beats the devil out of my little 2 stroke....of course it will only hold .65 string although I kind of "forced" .80 string its not a real powerful motor I can't cut real heavy stuff.

Milwaukee needs to hurry up and just make the sapling cutter attachment! I'm about to do this. Got an acre of saplings to cut

What happens if you hit a rock?

Ready for the zombie apocalypse! 😀

Crazy 😜 but I like it

Do you realize a sawblade will shatter where a brushblade will bend? Ya might want to get some chain link shinguards!

What can possibly go wrong 😂😂

You hit steel and your hurt as it shatters.

Circumcision tool.

Man at least wear shin guards and steel toe with that contraption.

Its cool untill you burn up the motor,thats A LOT more mass than its designed for,gas engine it dont matter but a electric motors cant handel it

looks like the saw is turning to wrong way

Stihl gas weed eater with square string will cut through branches and shit.

by the way NICE TRUCK!!

Woulda worked better if you didn't have the blade on backwards.
