This unit is a godsend for us Australians. All the DIY home units seem to have UK or US plugs and after shipping cost a bomb. Battery system means we don't have to worry about any of that.
Lightweight is good and what did I use it for it’s a lawnmower ua-cam.com/users/postUgkxTPN04aT-Qdjr_KS3ql7ng8wnU3wwsCqk also recommend Yes it is lightweight so hence not as robust as our old one. But if you take care it does the job really well.
This is listed as an 18v tool (even the American version). I’m feeling this IS an 18v tool - and the dual pack just extends runtime. I dont think this is a 36v motor like youre thinking. Theyre likely just combining the amp hours (how big the gas tank is essentially) from both packs, (wired in a Parallel circuit vs Series circuit) not the voltage. TTI owns Milwaukee and Ryobi. The cells used in the Ryobi packs are not the same as Milwaukee’s. That being said - I’m betting they incorporated dual batteries - cause people would say the tool sucked if it only ran for 20 minutes if it only had a space for a single battery. They just made it so you dont have physically switch from one battery to the next.
Oh I read the manual.. its very vague, and doesn't have and technical specs in it. In actuality it's an 8 page manual reprinted in dozens of languages for the European markets, then bound together.
It’s not 36v or anything other than 18v only. You don’t actually need two batteries at all. That “safety key” isn’t a safety key. You only need one 18v battery. The second battery location is just for a second battery. The red dongle you can pull out is an arrow locator. Your turn that red arrow key when you want to switch between the two batteries. Basically you install two batteries on the thatcher. You run the machine until your unit dies. You then pull out the red dongle key and turn it towards the other unused battery. The thatcher will now use that battery and leave the dead battery staying in the housing. The red dongle allows you to switch batteries without heading back to the house to swap out batteries. It’s how the new 40v push mowers work. I own one and it’s absolutely amazing.
Nope. You need two batteries. The red key is a safety to pull when changing batteries or blades. Runs both batteries in parallel. I ran the test to verify. Will show in a follow up video soon.
I don't know much about the 40v battery and equipment that uses it, but as a general homeowner who does little projects around the house, I made the decision to buy a Ryobi 18 volt drill combo unit several years ago when another brand I had no longer worked, and the main reason I chose Ryobi was because all of the research I did and the company themselves talked about the batteries remaining the same and not changing every few years making you buy new equipment. I say all that to simply say that I am glad that it's compatible with the batteries I have on hand, except I would agree that I need to upgrade from my 3 Ah to a 6 Ah set of batteries. I've been watching every sun Joe detacher / scarifier video I can find on UA-cam as well as some comparisons with the green works unit, and had just about decided to buy the second generation son Joe until I saw this video! I might have to wait a year and see if Ryobi will bring this unit to America so I don't have to order it from england. Thank you for the great review you have a new subscriber.
@@DadItYourselfDIY that is awesome, because even though I catch my grass 100% of the time I still need to detach it I'm starting to see areas where there's build up that needs to be broken up so my zoysia will spread.

we had them back in the 70s in the UK. they ran off can battery's. the problem was and probably still would be. they need very high torque to work well. not something battery kit does well if its cheep.

tell me about it. I am stuck with the ryobi platform and I wish it is available here. The Auger took a while to get here and I hope this is next. My issue is if they will keep it a dual 18v battery. 40v is useless to me.
@@DadItYourselfDIY I'm not seeing this anywhere, even their website says coming soon... Been looking for a dethatcher and all my power tools are ryobi, so it'll fit right in when available.
I have asked Ego for over 3 years to make a battery powered power rake like this, however they refuse to listen to the consumer! I will continue using my corded Green Works until they finally realize the competition is dominating this space.
I just finished my spring clean up (video on Saturday) And it went after it! I used two 6ah, and it did both my front and back (2500 Sq ft) but I own 15 Ryobi batteries, so that's never an issue.
Use a stick or something to prop the back door open (the door for the bag attachment). With the door open it will work much better. I do the same with my corded dethatcher.
If the batteries are in series they would make 36 volts, but you don't know that they are for sure.

Go get one....it's mostly plastic but rest assured you'll see the desirable results in your lawn. You won't believe how much thatch it kicks up if it's your first time.
That is an incredible amount of stuff pulled out of your lawn!! Are you sure it's 36 volts, it might be an 18v system with a long work time. Also, it is not 6 amps vs 4 amps. The 6ah stands for 6 amp hours and the 4 ah stands for 4 amp hours. The 6 simply goes longer before charging. When they are running low on charge they will cut out then run, then cut out.....
@@DadItYourselfDIY yeah, I started with the 18v tools and worked my way up to the 40v chainsaw and blower. So far the only thing I'm not a fan of is the mowers. My gas one still outperforms the electric by a long shot.
Do you think cutting an exit for the grass in the back would help it? The grass scene reminds me of the old lawn mowers without bags or side exits that clumped and the ‘bumped over’ the cut grass.
Reminds me of a hay bailer. I think if it wasn't climbing it would be harder to rake up. The bag that you can add would fill too often. Maybe figuring out a way to prop the rear door open slightly?!
They just announced today it will be coming out soon. I just ordered the sunjoe, but now thinking of canceling and waiting for this cordless. How much battery life was left after you did your front yard and side yard? Or your backyard?
I didn't check, but in did the entire front yard of 1500 sf with two 6ah batteries, same for the back which is 1,000 sf. There will be a Link in the video description as soon as Home Depot posts it!
Great video. I was really surprised at how much thatch was brought up. I'm very new to lawn care and have only fertilized and watered lawns. I usually use a bag with my walk behind mower. Do you think I would need to dethatch if I usually bag?
The yellow stuff is just dead grass it is not thatch, thatch is the top layer of soil that was dead grass that has fully decomposed and become brown soil. The scarifier digs into the thatch layer of the soil, power rake the one with the tines is just for raking which is the dead yellow grass up it will not dethatch, the scarifier will dethtch the yard. The dead grass will turn into thatch eventually. a lot of people use all of the terms interchangeably

@@DadItYourselfDIY 7:35 A 40V battery is electrically the same as two 18V batteries in series and similar if the two 18V are in parallel. One 6AH is 10 cells, two parallel sets of five 16850 cells in series. A 40V is two sets of ten 18650 cells in series. Those included 4AH are standard batteries... two 6AH or 8AH HP or High Performance packs would be optimal for higher amperage than the 4AH (since 4AH packs have one set of five 16850 cells). Assuming the 18650 cells are identical, the two parallel sets of 5 cells doubles the max amperage. Don't know why battery manufacturers list only capacity instead of max amperage, it's like advertising a car by size of gas tank (Ah capacity) instead of horsepower (amperage). Tool only would only cut 100 of the price, still too much for an occasional use, I'll deal with the hassle of a cord. Saw on your other video that the UK version is using the two packs in parallel not series. Assuming the cells are 20A C rate (C is max discharge rating), then a 40V pack is probably 40V x 20A = 800W. Two 6AH HP/High Performance is 20V x 80A = 1600W. The included 4AH cells would be 20V x 40A = 800W. The cells differ from different pack model numbers, and even between different years in the same model pack. Common C rates for 18650 cells are 10A, 15A, 20A, 25A, and 30A.
I really need a scarifier to put overseed this spring. I have a whole fleet of Ryobi 18V tools and batteries and really want to buy this machine. No one at either Ryobi nor Home Depot can translate "Coming Soon" into any kind of useful information. I hate the thought of a Sun Joe and super expensive 12-gauge 100' extension cord but that's what I'll do if I must. Can you help be with a better date for availability in USA?
How would you compare it to the sun joe? I know you briefly mentioned it at end but more info would have been nice. Here a thought for a video how about comparing the SunJoe vs Ryobi. Thanks for video.
The scarifier blade would have a small effect on bumps and divots. But using top dressing and sand leveling will be more effective in the long run. This is not a tiller or cultivator by any means.
In the video you swapped two genuine Ryobi batteries for two generic aftermarket 6AH batteries. Seemed to have more power - but could be more than the stated capacity that was at play such as the generic batteries allowing more current. I would imagine this brushless (HP) model will take full advantage of genuine batteries over generics when they hit the US. Was out dethatching with the Sunjoe today. Wonderful tool but destined for the curb as soon as the Ryobi 18v/36v/whatever version is available. And I'll be second in line to mod it to adapt a 40v battery. No reason to not be 40V from the start.
True true. The 6ah battery has 90 watts of power, the 3ah, only 54 watts. So definately more oompf.. the odd part is the European manual says ints 18v input, but the US version says 36v of input. Still need to dissect the unit deeper..
@@DadItYourselfDIY Both battery styles should have the same output current once you get into the middle of battery charge - in theory. Reality is often different. The generic batteries have a different output or output curve at various charge levels than the originals. Or the grass was more cooperative. Still gonna but one once they're in stock. Should be 10-15x faster than whipping a cord on every pass. Thanks for the video. Techtronics Ind. should send you a basket of cookies.
The one coming soon for the US market is advertised as a Dethatcher/Aerator. www.ryobitools.com/products/details/18v-one-plus-hp-brushless-dethatcheraeratorzaog
if you have a 3d printer you can make adapters to run the 40v line. News flash 40v is a marketing lingo. It's really 36v. just like all those 20v tools are really 18v
I have a question for you Sir or for anyone out there. I have several small Ryobi tools and porter cable. But when it comes to the larger items like this Dethatcher, it seems to me the cost of the larger batteries does not make this a cost efficient item. I would rather buy gas. Like with the Ryobi chainsaws. By the time you buy the 40 amp battery for a saw that’s worth anything you are up to the cost of an entry-level gas chainsaw. And for the environmental factor, these batteries are just like the batteries on electric cars; they have not figured out how to recycle them yet. Just wondering what your thoughts are? Thank you for your time.
It's a matter of scale.. I have multiple 40v tools therefore the battery cost are spread across those platforms, to scale I have 15 18v batteries for 50+ 18v tools
Good point sir. The more tools you have the more cost efficient it becomes as you were not buying a battery for each tool. Thank you so much for pointing that out and the quick response. I have subscribe to your channel.
As of yesterday 3/21 the dethatchers are in Ryobi's distribution warehouses and are making their way into Home Depot distribution and stores. Should start showing up online very soon, and stores right after that.
Any updates on the Ryobi? Still not available. I bought the Sun Joe. Worked ok but a real pain with the extension cord. Constantly getting tangled and easily unplugs. Will more than likely return it.
I printed the parts, but may just cannibalize a 40v charger and two 1.5ah batteries and glue it together for proof on concept then assemble an adapter after that if it all works.
Just wondering, most of these Battery/Electric units come with a bag and yes I understand it's too small to use but, can it be modified (cut) to avoid gathering or clumping in the underbelly? i.e. cut out the bottom of the bag or maybe the back? It just seems if there was a discharge method these units would be easier.
If the bag had a top that may be an option. I used a bungee cord to hold the flap partially open and that seemed to help with the clumping. There is a sweet spot for the flap that still directs the grass down and keeps it out of your face and allows free discharge of the debris.
I wish Ryobi had more stuff like this here in US! I see it has 18V, but it looks like it should be 40V! I'm confused about the 6A battery statements as well.
It's technically 36v, I don't think the have the 40v battery line in Europe. 6amp batteries have more oomph, this unit does a lot of work so it needs the power of a bigger battery.
@@DadItYourselfDIY Just a heads up, the box says One+. This is exclusively used for 18 volt series marketing. In Europe, I noticed that some of the tools can use TWO 18 volt batteries in parallel, which would effectively = 36 volts. The Bunnings listing states it uses two 18 volt batteries to "gain maximum results." www.bunnings.com.au/ryobi-2-x-18v-one-brushless-scarifier-tool-only_p0250384 Thanks for the video! I really wish they would bring this to the United States! I would definitely buy it if it was available.
@@DadItYourselfDIY If they're in parallel, it's still 18v but if they're in series then it's the 36v motors. oops - I kept on reading and noticed that's already mentioned.
wow so $278 plus $175= $453 and the sunjoe at walmart is only $120 free shipping. the amazon $179 is for the bigger sunjoe. Also the sunjoe comes with the rake and the scarifier. I just got the sunjoe and I have all EGO lawn and tools so I love the battery for my lawn care but the extension cord isn't that bad plus I saved $321 after taxes. Did the Ryobi struggle even after you put the 6 amp batteries to get the big piles of thatch? Was that just the video? I'm glad that they are making these with a battery. Thanks for the video.
No more struggles after the battery change.. I'm not defending the price because the shipping from the UK was nuts. But the price of the unit itself was comparable to the other cordless versions on the market now.
@@DadItYourselfDIY Hey Thanks for getting back. I'll Subscribe. I liked your video. I am amazed by how much thatch comes out of the sunjoe and the Ryobi. Do you use the Scarifier more than the Rake? Maybe I should do that on my lawn instead of the power rake thing. Thanks for the info. I will probably get one of these once it hits the US. You should hit up Ryobi for your work. I bet a ton of people get one because of you video.
Will it run with only one battery installed? It says "18v" on the box, so I'm assuming it can run even if only one battery is installed. It may be that it runs them either sequentially (1 then the other) or in parallel (resulting in it running at 18v). If it runs them in a serial configuration (@36v and won't run with just 1 battery) then MAYBE you could hack it to run on a 36/40v battery. I'm still not sure I would do it, though.
What do you expect the runtime to be with the 2 batteries. Where were your 6ah batteries charged to after the work done in this video? Could you roughly translate that to a guess on acreage? 1/2 acre on 2 6ah batteries? More less?
I was able to easy do my front yard on a single charge, which is 1,500 sf. I live on a corner lot, so an area about 15 feet from the house to the street and 100 feet long. I'd say roughly 1/8 acre. I didn't check to see where the batteries were at, but do know they ran until I was done.
I was wondering would I able able to use a cultivator and then use this detacher/aerator to take out dead grass from turned over dirt? If not is there something I can use to do it?
@@DadItYourselfDIY thanks for the reply. Yeah that old school rake just takes a lot of time lol. Was looking on something to make things quicker and easier. Thanks for letting me know. I still plan on getting this when it comes to the USA for the grass. Great review.
I have the SunJoe and know its comparable to the Greenworks in price and operations. I am happy with its performance and have been for years. But having a cordless tool is a game changer!
@@DadItYourselfDIY i have a large front yard and even bigger backyard and on one side of the house I have side yard that is decent in size. I’d probably have to invest in multiple batteries
My UK was tool only and did not include anything, including the power rake blade. The US version includes a charger and 2 4ah batteries, both blades, and the collection bag.
@@DadItYourselfDIY Thanks for the quick response. Got me to go look at it one more time to consider buying it and it dropped to $399.. so I pulled the trigger, then a few minuets later it jumped back to $429... Not sure why the price is fluctuating but I am glad I got the $30 discount.
You have to be careful about those knock off batts. My 6 amps perform like my Ryobi 4 amp ones. That being said, how deep into the soil was this able to cut?
no, it doesn't. Get a sun joe that wont stall out on you. I have absolutely no idea why Ryobi didn't make this a 40v tool. Extremely disappointing and I love Ryobi. Running larger Amp Hr batteries will not equate to more voltage, torque, etc. It only allows for longer runtime. Voltage is voltage.
Do you know how much square footage you did with this unit? I've got just under 15k and while I own and have used the sunjoe, the cord is definitely a bit of a pain to manage.
Do you use genuine Ryobi batteries, or generic ones from ebay? I think this machine is definitely worth the money. How often does one need to dethatch the lawn?
I just ordered two HP 6ah, but only own 1 4ah currently.. but I think two 4ah batteries would work fine. I being told that the unit ships with 2 4ah, not not sure which flavor.
@@DadItYourselfDIY oh ok. Good to know. I'm sure they will ship the old 4ah batteries, every promotion they have includes the old batteries because they are trying to unload them all
That is a really neat to have.
I have to say, I am impressed with Ryobi. They consistently make good and affordable cordless devices.
I would agree!

It's nuts!
That is an incredible amount of stuff pulled out of your lawn!!
Are you sure it's 36 volts, it might be an 18v system with a long work time. Also, it is not 6 amps vs 4 amps. The 6ah stands for 6 amp hours and the 4 ah stands for 4 amp hours. The 6 simply goes longer before charging. When they are running low on charge they will cut out then run, then cut out.....
It's definitely 36v.. watch the follow on videos! Thanks for the feedback too!
Will the lawnmower grass collector bag work with the dethatcher?
I don't know. I don't own any of their mowers.
Good news, it's coming here! Just announced it.
Saw it!
18v ? I have the 40v trimmer, I don't need another battery platform to add to my milwaukee, ryobi 40, greenworks and ego !
I don't blame you, but a majority of people who are in the Ryobi 40v line are usually already invested into the 18v ecosystem as well.
@@DadItYourselfDIY yeah, I started with the 18v tools and worked my way up to the 40v chainsaw and blower. So far the only thing I'm not a fan of is the mowers. My gas one still outperforms the electric by a long shot.
I still have a gas mower as well. But when it dies I'm going electric.
Hi great video, I was wondering if I could use a 9ah batteries?
Easily
Do you think cutting an exit for the grass in the back would help it? The grass scene reminds me of the old lawn mowers without bags or side exits that clumped and the ‘bumped over’ the cut grass.
Reminds me of a hay bailer. I think if it wasn't climbing it would be harder to rake up. The bag that you can add would fill too often. Maybe figuring out a way to prop the rear door open slightly?!
nice edging of the sidewalk
It's my signature. Being on a corner lot makes it that much more important. My neighbors couldn't be bothered.
So you used the aerator blade and not the sweeping blade in this video?
Yes, the scarifier cylinder. The UK version doesn't include the power rake cylinder. Calling this an "aerator" is a stretch.
Hi Scott, I had never even heard of this. This is awesome. I just put my man onto your channel too. He loves this type of stuff.
Thanks for that! Love your channel as well! Hope you are doing well!
They just announced today it will be coming out soon. I just ordered the sunjoe, but now thinking of canceling and waiting for this cordless. How much battery life was left after you did your front yard and side yard? Or your backyard?
I didn't check, but in did the entire front yard of 1500 sf with two 6ah batteries, same for the back which is 1,000 sf. There will be a Link in the video description as soon as Home Depot posts it!
Grass looked like it could of done with a quick mow before you started the scarify 🤔
I did mow it!
Great video. I was really surprised at how much thatch was brought up. I'm very new to lawn care and have only fertilized and watered lawns. I usually use a bag with my walk behind mower. Do you think I would need to dethatch if I usually bag?
I bag every time, and still run the dethatcher twice a year.
The yellow stuff is just dead grass it is not thatch, thatch is the top layer of soil that was dead grass that has fully decomposed and become brown soil. The scarifier digs into the thatch layer of the soil, power rake the one with the tines is just for raking which is the dead yellow grass up it will not dethatch, the scarifier will dethtch the yard. The dead grass will turn into thatch eventually. a lot of people use all of the terms interchangeably

You are correct. I use the power rake in the Spring and scarifier in the Autumn
Love Ryobi tools and have a bunch on One gear, but it’s almost 500 bucks. The Sun Joe was 120…. That’s a ridiculous premium for brand loyalty.
They should consider a tool only option to bring the price point down.
@@DadItYourselfDIY 7:35 A 40V battery is electrically the same as two 18V batteries in series and similar if the two 18V are in parallel. One 6AH is 10 cells, two parallel sets of five 16850 cells in series. A 40V is two sets of ten 18650 cells in series. Those included 4AH are standard batteries... two 6AH or 8AH HP or High Performance packs would be optimal for higher amperage than the 4AH (since 4AH packs have one set of five 16850 cells). Assuming the 18650 cells are identical, the two parallel sets of 5 cells doubles the max amperage. Don't know why battery manufacturers list only capacity instead of max amperage, it's like advertising a car by size of gas tank (Ah capacity) instead of horsepower (amperage). Tool only would only cut 100 of the price, still too much for an occasional use, I'll deal with the hassle of a cord.
Saw on your other video that the UK version is using the two packs in parallel not series. Assuming the cells are 20A C rate (C is max discharge rating), then a 40V pack is probably 40V x 20A = 800W. Two 6AH HP/High Performance is 20V x 80A = 1600W. The included 4AH cells would be 20V x 40A = 800W.
The cells differ from different pack model numbers, and even between different years in the same model pack. Common C rates for 18650 cells are 10A, 15A, 20A, 25A, and 30A.
Good breakdown.
Great video! Thank you. What kind of grass do you have? Fescue, Bermuda, Zoysia?
I have cool season grass. A bluegrass, fescue, rye mix.
Perfect video. Can’t get better then this . Thank you ⭐️⭐️⭐️⭐️⭐️🇨🇦
Thank you for the support!!
Wish Ryobi would bring the reel mower to the states.
That's my next goal!!
I really need a scarifier to put overseed this spring. I have a whole fleet of Ryobi 18V tools and batteries and really want to buy this machine. No one at either Ryobi nor Home Depot can translate "Coming Soon" into any kind of useful information. I hate the thought of a Sun Joe and super expensive 12-gauge 100' extension cord but that's what I'll do if I must. Can you help be with a better date for availability in USA?
Literally any day now. My brand manager told me March.
I’ll stick with my sun joe. Love the ryobi line, but no need to “upgrade”
I'm not getting rid of my SunJoe either.
To ship a sunjoe to Oz would be $350... even if I could find a 240v one. So this is promising.
But you have the RYOBI!!
I can’t find them listed here but shouldn’t be too long.
Maybe we could make a trade, I send you a scarifier and you send me the cylinder mower..
I just got my dad a ryobi 40v HP mower and this dethatcher would be perfect if it used the same batteries.
Unfortunately it uses the 18v.
For the ASMR fan club, please include more real-time, no music footage. Love the sound of it running.
It does have a nice hum. I am using less music in my more recent videos.
That's good material for a compost pile. No sense sending it to a landfill 😁
We have green collection. It gets ground up into mulch...
I'm going to.wait for it to come here with the 40v that fits my other Ryobi tools
I do not think it's going to be offered in 40v.
Oops. Landed at the wrong video channel. This is Dad It Yourself (DIY) and I'm, unfortunately, a widow. Dang. Off to look for the WIY channel.
Hahaha.. I can still help!!
How would you compare it to the sun joe?
I know you briefly mentioned it at end but more info would have been nice.
Here a thought for a video how about comparing the SunJoe vs Ryobi.
Thanks for video.
Same performance, no cord!
A 3D printed 40v adapter? Tell me more, did you do this?
Not yet. It's in the works to tie in with my Spring dethaching video.
How would this be to more uneven soul? And how about roots in the ground? 😀
The scarifier blade would have a small effect on bumps and divots. But using top dressing and sand leveling will be more effective in the long run. This is not a tiller or cultivator by any means.
The 6Amp batteries aren't outputting 6 amps, they're "6 ampere hour" batteries. All the Ryobi One+ batteries output at the same amperage.
Correct. Lesson learned
In the video you swapped two genuine Ryobi batteries for two generic aftermarket 6AH batteries. Seemed to have more power - but could be more than the stated capacity that was at play such as the generic batteries allowing more current. I would imagine this brushless (HP) model will take full advantage of genuine batteries over generics when they hit the US.
Was out dethatching with the Sunjoe today. Wonderful tool but destined for the curb as soon as the Ryobi 18v/36v/whatever version is available. And I'll be second in line to mod it to adapt a 40v battery. No reason to not be 40V from the start.
True true. The 6ah battery has 90 watts of power, the 3ah, only 54 watts. So definately more oompf.. the odd part is the European manual says ints 18v input, but the US version says 36v of input. Still need to dissect the unit deeper..
@@DadItYourselfDIY Both battery styles should have the same output current once you get into the middle of battery charge - in theory. Reality is often different. The generic batteries have a different output or output curve at various charge levels than the originals. Or the grass was more cooperative. Still gonna but one once they're in stock. Should be 10-15x faster than whipping a cord on every pass.
Thanks for the video. Techtronics Ind. should send you a basket of cookies.
Much better than a cord!!!!
It would be awesome I’d the thatch bar could be replaced with an aerator
Unit isn't heavy enough for that..
The one coming soon for the US market is advertised as a Dethatcher/Aerator.
www.ryobitools.com/products/details/18v-one-plus-hp-brushless-dethatcheraeratorzaog
But it is not an aerator as we all know it..
What do you mean, “not as we know it”? From Ryobi’s video on upcoming us products, the US version will have a swap able barrel with an aerator option.
I've seen the two blades. One is a power rake the other is a scarifier, exactly like the SunJoe and Greenworks. Not a plug aerator blade.
which would you rather deal with? this or dragging the extension cord around on a sun joe or greenworks?
Cordless all the way!!
I wish Ryobi would do more of the 36v tools. I really don’t want to get into the 40v line. Simply because it’s another battery line to be in
I think the 40v are great for the yard stuff, but you're right two 18v is more convenient.
if you have a 3d printer you can make adapters to run the 40v line. News flash 40v is a marketing lingo. It's really 36v. just like all those 20v tools are really 18v
This is just what I need. Hopefully ryobi will sell it here soon.
They would make a killing, maybe it will be one of the tools they announce on the 20th.
@@DadItYourselfDIY they did!
I have a question for you Sir or for anyone out there. I have several small Ryobi tools and porter cable. But when it comes to the larger items like this Dethatcher, it seems to me the cost of the larger batteries does not make this a cost efficient item. I would rather buy gas. Like with the Ryobi chainsaws. By the time you buy the 40 amp battery for a saw that’s worth anything you are up to the cost of an entry-level gas chainsaw. And for the environmental factor, these batteries are just like the batteries on electric cars; they have not figured out how to recycle them yet. Just wondering what your thoughts are? Thank you for your time.
It's a matter of scale.. I have multiple 40v tools therefore the battery cost are spread across those platforms, to scale I have 15 18v batteries for 50+ 18v tools
Good point sir. The more tools you have the more cost efficient it becomes as you were not buying a battery for each tool. Thank you so much for pointing that out and the quick response. I have subscribe to your channel.
Thanks for your support!
So is the Ryobi available in the U.S.? I still can’t find. Also, in your honest opinion, is the the Sun Joe just as good as the Ryobi?
As of yesterday 3/21 the dethatchers are in Ryobi's distribution warehouses and are making their way into Home Depot distribution and stores. Should start showing up online very soon, and stores right after that.
The thing with the Ryobi is its cordless and you can use existing batteries.
But as far as performance, Sun Joe worked just as well as the Ryobi?
Mechanically the are identical
Any updates on the Ryobi? Still not available. I bought the Sun Joe. Worked ok but a real pain with the extension cord. Constantly getting tangled and easily unplugs. Will more than likely return it.
The safety key is actually also a fuse, not just a jumper.
Nice.. nothing in the manual says that. It's called a "switch key" but a fuse would be a nice protective device.
Any update on the 3D printed adapter for the 40v battery??
I printed the parts, but may just cannibalize a 40v charger and two 1.5ah batteries and glue it together for proof on concept then assemble an adapter after that if it all works.
@@DadItYourselfDIY looking forward to the vid...
Soon!
We’re you able to change blade over to a dethatcher blade?
Finally came back and on order. Should have it in a week!
I wonder where do you dispose all those dead grass?
We haveva green bin that the city collects weekly and is taken to be recycled into garden mulch.
Just wondering, most of these Battery/Electric units come with a bag and yes I understand it's too small to use but, can it be modified (cut) to avoid gathering or clumping in the underbelly? i.e. cut out the bottom of the bag or maybe the back? It just seems if there was a discharge method these units would be easier.
If the bag had a top that may be an option. I used a bungee cord to hold the flap partially open and that seemed to help with the clumping. There is a sweet spot for the flap that still directs the grass down and keeps it out of your face and allows free discharge of the debris.
Nope! Home Depot USA currently does not carry this. Coming soon to USA per Ryobi.
Next Month!! Too late for the fall season.
Priced at a ridiculous $429 at my local Home Depot (Ohio, USA).
It's the batteries
Yea ill keep my corded sun joe . Not spending 500 bucks on something I might use once a yr
Fair enough. Batteries are expensive
I wish Ryobi had more stuff like this here in US! I see it has 18V, but it looks like it should be 40V! I'm confused about the 6A battery statements as well.
It's technically 36v, I don't think the have the 40v battery line in Europe. 6amp batteries have more oomph, this unit does a lot of work so it needs the power of a bigger battery.
@@DadItYourselfDIY Just a heads up, the box says One+. This is exclusively used for 18 volt series marketing. In Europe, I noticed that some of the tools can use TWO 18 volt batteries in parallel, which would effectively = 36 volts. The Bunnings listing states it uses two 18 volt batteries to "gain maximum results."
www.bunnings.com.au/ryobi-2-x-18v-one-brushless-scarifier-tool-only_p0250384
Thanks for the video! I really wish they would bring this to the United States! I would definitely buy it if it was available.
You are correct. It uses two 18v batteries..
@@DadItYourselfDIY If they're in parallel, it's still 18v but if they're in series then it's the 36v motors.
oops - I kept on reading and noticed that's already mentioned.
Are you assuming they are in Parrallel because of the labeling or have you seen a wiring schematic to verify?
It seems like it would perform better if it was designed as a pull unit.
Not sure. Every design from small corded to large commercial units all are walk behind forward units.
wow so $278 plus $175= $453 and the sunjoe at walmart is only $120 free shipping. the amazon $179 is for the bigger sunjoe. Also the sunjoe comes with the rake and the scarifier. I just got the sunjoe and I have all EGO lawn and tools so I love the battery for my lawn care but the extension cord isn't that bad plus I saved $321 after taxes. Did the Ryobi struggle even after you put the 6 amp batteries to get the big piles of thatch? Was that just the video? I'm glad that they are making these with a battery. Thanks for the video.
No more struggles after the battery change.. I'm not defending the price because the shipping from the UK was nuts. But the price of the unit itself was comparable to the other cordless versions on the market now.
@@DadItYourselfDIY Hey Thanks for getting back. I'll Subscribe. I liked your video. I am amazed by how much thatch comes out of the sunjoe and the Ryobi. Do you use the Scarifier more than the Rake? Maybe I should do that on my lawn instead of the power rake thing. Thanks for the info. I will probably get one of these once it hits the US. You should hit up Ryobi for your work. I bet a ton of people get one because of you video.
I use the rake more in the front and the scarifier in the back...
Nice video.
Thanks!
how about a reel mower!
They have a Ryobi one in Australia, but have not been able to get my hands on one!!
ua-cam.com/video/rmW_rLmRheo/v-deo.html
So this is a push detacher, just bought a sun joe . So I have to try my joe
Same same without the cord, unless you bought the cordless sunjoe?
Will it run with only one battery installed? It says "18v" on the box, so I'm assuming it can run even if only one battery is installed. It may be that it runs them either sequentially (1 then the other) or in parallel (resulting in it running at 18v). If it runs them in a serial configuration (@36v and won't run with just 1 battery) then MAYBE you could hack it to run on a 36/40v battery. I'm still not sure I would do it, though.
It needs both batteries, and runs in a 18v parallel configuration.
What do you expect the runtime to be with the 2 batteries. Where were your 6ah batteries charged to after the work done in this video? Could you roughly translate that to a guess on acreage? 1/2 acre on 2 6ah batteries? More less?
I was able to easy do my front yard on a single charge, which is 1,500 sf. I live on a corner lot, so an area about 15 feet from the house to the street and 100 feet long. I'd say roughly 1/8 acre. I didn't check to see where the batteries were at, but do know they ran until I was done.
Shoot! I bought an Earthwise a few years ago!
Well the Ryobi will be a future option!
I was wondering would I able able to use a cultivator and then use this detacher/aerator to take out dead grass from turned over dirt? If not is there something I can use to do it?
No.. you will damage the unit.. A good old fashion stone rake and leaf rake it what you need.
@@DadItYourselfDIY thanks for the reply. Yeah that old school rake just takes a lot of time lol. Was looking on something to make things quicker and easier. Thanks for letting me know. I still plan on getting this when it comes to the USA for the grass. Great review.
Thanks I'll announce it here when the link goes live!
How would that work on St Augustine?
I am not familiar with warm season grasses. I have a cool season lawn.
Ok how do you pick up the dead grass?
You can rake it or run a bag mower over it.. I do both..
With the Ryobi Dead Grass Scooper of course!!!🤣
I REALLY want the new 40v crosscut mower!
Guys, we all know you mow before using a scarifier right. Mow as low as you can!
We do!
Great video, I have a couple of 2.5 AH and one 5 AH. Do you know if it works with two different types of batteries 2,5AH together with 5AH?
it will be a very short run. the 2 batteries are interdependent. The lower amp battery will die first and shut off the unit.
I wouldn't run it with anything less than 2 5ah..
Correct..
@@DadItYourselfDIY ok, I did buy it yesterday so it will be interesting to test. Thanks for the response.
Great.. I just posted a picture of my backyard on my Instagram....
I hope the make 40v one for the US
Don't we all. But I'm pretty happy with this one!
It’s awesome the amount of work you completed with this one.
Yeah.. it always shocks me how mush accumulates every year.
How would you compare the Ryobi with the Greenworks dethacher?
If you are talking about the corded greenworks,I have it and absolutely love it. One of the best investments I’ve made for my lawn
I have the SunJoe and know its comparable to the Greenworks in price and operations. I am happy with its performance and have been for years. But having a cordless tool is a game changer!
I don't have the Greenworks. But the performance of the the Ryobi to my SunJoe is comparable.
@@DadItYourselfDIY i have a large front yard and even bigger backyard and on one side of the house I have side yard that is decent in size. I’d probably have to invest in multiple batteries
Well I'm fortunately, I have 10 totally batteries, but only 2 of the 6ah.. so we will see. I do need to invest in some bigger batteries
I wish EGO would make one.. great vid btw
They have a solid following, it's only a matter of time.
Agreed, Ego needs to hurry up. Side note would love to see the 3d printed adapter for the bigger battery.
They jus announced it's arrival to the US.
Yes they did!! P2740!
No 40v Ryobi dethatcher?
Nope.. 18v
It's a 18V🙌😍!
YES!
It is!
So how long did the battery last?
I was able to do the whole front section 1500sf with one set of batteries.
Any idea when these will be available in USA?
None. But I check everyday.
Its now available in the US and its listed as $429 !!! WTF thats even more than you got it from the UK! or did it not come with batteries from the UK?
My UK was tool only and did not include anything, including the power rake blade. The US version includes a charger and 2 4ah batteries, both blades, and the collection bag.
@@DadItYourselfDIY Thanks for the quick response. Got me to go look at it one more time to consider buying it and it dropped to $399.. so I pulled the trigger, then a few minuets later it jumped back to $429... Not sure why the price is fluctuating but I am glad I got the $30 discount.
I wish they would offer a tool only version. We have enough batteries.. 😀
You have to be careful about those knock off batts. My 6 amps perform like my Ryobi 4 amp ones. That being said, how deep into the soil was this able to cut?
I just scratch the surface so probably 1/4" to 1/2"
disappointed its not 40v to go with my mower... I guess its the Sun Joe for me .
One of the down falls. But they do not push to 36v/40v line in Europe.
With it being a 18V tool, does it have enough power?
Yes
no, it doesn't. Get a sun joe that wont stall out on you. I have absolutely no idea why Ryobi didn't make this a 40v tool. Extremely disappointing and I love Ryobi. Running larger Amp Hr batteries will not equate to more voltage, torque, etc. It only allows for longer runtime. Voltage is voltage.
I have a SunJoe. Hate the cord.
How much are the 6 amp battery?
$250 at HD for a two pack. homedepot.sjv.io/AWm5xN
Is that just 1 year's thatch?
Yes!
When and why would one do this ?
Annually to increase soil exposure for seeds and fertilizers.
Do they have a 40v version? I’m on the 40V system but not on their 18V system.
They do not.
Do you know how much square footage you did with this unit? I've got just under 15k and while I own and have used the sunjoe, the cord is definitely a bit of a pain to manage.
I have 2500 sf..
Been waiting for 2 years. Still not available in usa. Losing fath in my royobi decision.
I sentva followup email to my brand manager this morning.
Do you use genuine Ryobi batteries, or generic ones from ebay? I think this machine is definitely worth the money. How often does one need to dethatch the lawn?
I use both. Twice a year. Spring to prep for fertilizers and fall for overseeding.
Anyone try the HP batteries in this? Wondering if a 4HP would work better
I just ordered two HP 6ah, but only own 1 4ah currently.. but I think two 4ah batteries would work fine. I being told that the unit ships with 2 4ah, not not sure which flavor.
@@DadItYourselfDIY oh ok. Good to know. I'm sure they will ship the old 4ah batteries, every promotion they have includes the old batteries because they are trying to unload them all
It's all about the $$
