RYOBI Dethatcher/Scarifier | You have QUESTIONS? I have Answers! | 2021/30

I recently published a video about the Ryobi Dethatcher/Scarifier from the UK. This unit is now available in the United States as the P2740 from Home Depot! This is part of the 18V ONE+ line, but uses TWO 18V batteries, for extended run time. This is NOT a 36V tool.
That video can be seen here: • NEW Ryobi Dethatcher/S... I have also done a couple of review and demonstration videos on the SunJoe Dethatcher. Those are here: • New SUN JOE AJ801E Det... and here: • The Sun Joe AJ801E DET... for your reference.
After I published this video there were many questions. Mostly about the batteries, was it an 18V or 36V system, was the US unit going to be a 40V tool, and what was the life of the batteries.
The next question was about the catch bag, or should I just let the thatch drop? use a mower? How did I clean up? Which blade works best? and what accessories are included.
And finally there we questions about the durability and quality of the unit, how did it compare to the Greenworks or the SunJoe dethatchers. Was the battery unit as good as a corded power unit?
I hope I answered everyone;s questions, and much more! Thank you for your support!

I was hoping they were going to release it as a 40v battery so i wouldn't have to buy new ones, but this looks GREAT!

[@DadItYourselfDIY]

I thought so at first, and the extra weight wouldn't hurt.. but I'm good with it!

[@diydaddoes9710]

Thanks for the follow up video. It helped me understand more about how the batteries are gonna work. I definitely look forward to cutting the cord

[@DadItYourselfDIY]

Thanks, glad it helped!

[@GraphixJunkie]

Thanks for the info. As for the batteries, I have 2 comments. 1. I always compare the voltage of the battery to the size of the engine and the amp hours to the size of the gas tank. A higher amp-hour capacity should just equate to a longer run time in most cases. 2. This tool is in their "HP" line. While normal non-HP batteries will work in them, they are designed to be used with the HP batteries. Most if not all of their brushless tools work better with the new batteries. The new batteries have extra contacts on the post that provide communication to the tool to be able increase the discharge rate under high loads. The normal batteries don't have this so you end up with lower max power output of the tool. I'm looking forward to these releasing in the states soon.

[@DadItYourselfDIY]

I guess it has disappeared from the website, so who knows.

[@GraphixJunkie]

@@DadItYourselfDIY I think it's still there (at least the Ryobi site). I haven't looked for it on home Depot. I'm bummed they are dragging their feet releasing this late in the season. I think this and the upgraded 18v pressure washer aren't releasing until fall... Ugh

[@DadItYourselfDIY]

That's the rumor. Save your pennies. I hear $399

[@GraphixJunkie]

@@DadItYourselfDIY I really wish they didn't force me to buy more batteries and another charger. Sometime Ryobi makes dumb choices. I'm going to write them an email asking why they won't release it as tool only. Seems unnecessary. They could always have the 2 pack of batteries as a recommended add-on but don't force me. Really annoying. That has to add at least $100 to the price I'd bet.

[@DadItYourselfDIY]

Easily

[@GWHAWK87]

Watt hours also doesn't explain increased power as it merely can be increased by delivering the same amount of power for longer (ie not more power). Chances are it is self regulating power output to get longer run times on smaller batteries.

[@DadItYourselfDIY]

Unsure, I just know the unit runs better with 6ah than it does with 3ah.

[@GWHAWK87]

@@DadItYourselfDIY At the end of the day that's the message isn't it lol. Well unfortunately I have a 6 week wait until this lands in Australia :( Also - looks like I will be buying some 6Ah batteries! I have an Ego Chainsaw that I know chokes the performance of the 2aH battery compared to the 4aH one to save battery time.

Well at least you KNOW when it's coming.

[@benwade19]

I have the 36volt mower and it works great. I also have the string trimmer and edger that use the same batteries. I sure don’t want to buy more batteries that would only be used for the detacher. Ryobi needs to make one that uses the 40 volt system. Thanks fora very informative and well done video.

[@slpurvis1]

Ahhh trolls...good for boosting the number of comments on a video but pretty much useless for all other matters lol. So I have 2 request. Wait, first off your 4 gallon backpack sprayer video on the roof sold me on one for myself. I love that tool. It got me back in the Ryobi lineup. I run yellow and red stuff but some of Ryobi’s niche tools are absolutely brilliant and affordable. Now back to the requests. I’d really like to see a short clip of de thatching with the rear door propped open. Maybe you can find a neighbor or community park since your yard is pretty squared away. Second I’d really like to see if A) the Dewalt battery adapter with Dewalt batteries fits under the cover and If not by how much it misses and B) run it with DeWalts 5.0 and 6.0 20v XR batteries and give feedback on power output. I have an adapter because I have a dozen 20v 5.0ah batteries alone and the Dewalt batteries really get all a Ryobi motor has to give as several KZbin videos will prove. Torque Test Channel has a particularly interesting battery comparison on the new Ryobi mid torque impact. Thanks for your quality content!

[@kevind.8627]

Thanks for all the info. Not to be predantic but watt hours are a measure of energy. A Wh number on the battery doesn't tell you which can put out more power. Power is measured in just watts.

[@DadItYourselfDIY]

Do what explains the bigger batteries working better? Just better charged?

[@kevind.8627]

Sorry. I'm no battery expert. There could be lots of differences between your two batteries. All I know is that the Wh explanation is like saying a 4 gallon sprayer can shoot water farther than a 1 gallon sprayer. The Wh is a measure of storage not how quickly the electricity can be used by the motor.

[@DadItYourselfDIY]

Interesting. I'll have to try different sets of my 3ah batteries to see if I get different results.

[@jakenz00]

@@DadItYourselfDIY The difference that will determine if a battery is more powerful than another will, in this case, generally be the dimensions of the pack, the thicker packs being more powerful. This is due to these pack having an extra row of cells. The thinner packs have 5 cells in series, where the thicker have 2 in parallel for each series connection, or 5s2p (5series2parallel) this enables a greater current draw from the pack.

[@DadItYourselfDIY]

I assumed this but people will argue your point that they are are 18v and there is no difference.

[@craigd10]

I'm looking forward to getting one of these when they become available. I was never going to buy a corded one, and it appears this will be the only cordless model on the market. According to the website, the U.S. version will come with two 4 Ah batteries, so that appears intended to be sufficient power without going up to the 6 Ah. I'm hoping they release a tool-only version.

[@DadItYourselfDIY]

Hope so for price sake.

Kinda tricky.. it was 207 British pounds or about $290. Plus shipping. I ended up paying $474 total. This was a tool only unit from the UK. The US version is supposed to come with all the accessories and two 4ah batteries with a charger. I've heard prices in the $300 range, but nothing has been confirmed.

[@jmacfarlan]

I contacted Ryobi and they said it’s still Coming Soon and for any availability and pricing questions I need to contact Home Depot. I contacted Home Depot and they said they don’t have any information about when it’s coming out. I need it for the fall reseeding (late August) so I hope it’s soon

@@DadItYourselfDIY ideally they have a tool only option too as I’m sure a lot of Ryobi fans already have 18v batteries and chargers

[@DadItYourselfDIY]

I would hope and agree with that..

[@SeptemberRain804]

Most of my non-lawn related power tools are Ridgid but I recently started to invest into Ryobi 40v for lawn tools (trimmer which allows for my previously acquired Expand-It attachments and the 18 inch chainsaw). Doesn’t make sense to me why this isn’t part of the 40v platform. Thought heavy duty lawn related tools define the 40v playform. Seems more effective than my tow behind Agri-Fab tine dethatcher. Would be perfect (for me anyways) if on singular 40v battery and if it allows for aerator attachment. However I imagine as an aerator it would require ability to add weight to drive plug blade into the soil so maybe not. I’m liking the Ryobi 40v platform so far. 40v Cultivating 8” Auger next!

[@DadItYourselfDIY]

I love my 40v tools as well. I'm going to do some experimenting to see if I can go 40v..

[@tc3261]

Mine keeps cutting out after like 2 small lines when it isn’t full and refuses to restart. Takes like 5 minutes. Any ideas??

[@DadItYourselfDIY]

I dont use the colection bag. Its probably overheating the motor, or your batteries ate not fully charged, you need to use a 4ah or higher. I use a 6ah. While in reality there is no difference in the voltage, the 6ah has more watts to "push" the motor.

[@tc3261]

@@DadItYourselfDIY we use a 6ah the new one. Got it today. And it does about 10metres and stops. I don’t think this lawn has been done in a long time. Would it just be because it’s overdue?

[@DadItYourselfDIY]

Raise the tines up, and see if it runs on a lighter pass..

[@PsychOut101]

Thanks for the review. Can I ask how you know the batteries are in parallel and not series? Given it did not work on one battery suggests it could be in series where a second battery would be needed to complete the circuit but they may just have added an extra safety/load management feature.

[@DadItYourselfDIY]

They are in series, 18+18 = 36 (40). I did a couple of other tests, including wiring in a 40v battery.

[@PsychOut101]

Thanks that's good news. Prefer to get the 18v batteries as I have nothing in their ecosystem but are more likely to use their 18v tools as I have all ego gear for the garden

[@DadItYourselfDIY]

The 6ah work awesome in this tool..

[@timlarson1142]

Nice video. However, this is a 36 volt tool. It listed as such in the manual. 18v is just the battery platform. Thanks for posting.

[@DadItYourselfDIY]

I would agree, except the European version says it's 18v, hence the confusion.

[@timlarson1142]

@@DadItYourselfDIY odd. The USA site actually has the European manual and that’s where I saw the specs. Pull the cover off and look at the label on the motor. That would be definitive.

[@apmiller77]

After adding the price of two 6 amp batteries, this is one very expensive machine, if you don’t already have them from being in RYOBI’s “echo system”. Even if you go with lesser amps.

[@DadItYourselfDIY]

Fortunately I am already heavily invested in the Ryobi ecosystem, with 20 18V batteries. this is a big factor in what tools I purchase. I also have three of the 40v batteries, and the 12v, and Tek4 batteries, so their entire line is available to me at no additional cost for batteries.

[@peterkelly2492]

Ive just bought one but I think mine is running backwards. Its hard to push and leaves a big pile at the front at the end of the row. With the scarrifier attachment, i take it that the straight edge is the blade and not the curved side? Im thinking that the straight edge should cut down into the lawn then flick the thatch backwards into the bag? Mine currently cuts on the curved side, then the thatch is made to go forwards up and over the blade assy then into the bag. It doesnt seem right to me

[@DadItYourselfDIY]

It should claw into the grass and pull the unit forward. The debris should go out the back of the unit into the bag or discharge as you walk along.

[@peterkelly2492]

@@DadItYourselfDIY I took it apart but all 3 wires to the motor were correctly connected. I took it back and got another which is running the right way.

[@DadItYourselfDIY]

[@ciap1]

Watt-hours is not power. It's energy. Amp hours multiplied by the voltage is the Watt-hours. What you should consider when powering the unit it the volts. The bigger batteries maintain the voltage for longer than the smaller ones. 'Power' is not the battery capacity. This must be a symptom of the archaic imperial system.

[@DadItYourselfDIY]

I have found that this motor just requires more amps.. the 3ah batteries just seem to work for short periods of time, and cannot handle the "draw". 6ah, no issues at all. But this is probably why the US version will be delivered with 4ah. I can only imagine the runtime for me with 9ah. My entire front, back and side lawns over 2,500 sf in one run.

[@ecospider5]

In general you are right. But within the Ryobi eco system you can assume a higher ah battery is going to give you more instantaneous amps. This is because they mainly use the same cells within there batteries. So the 1.5ah and 2.0ah batteries use 5 cells. The 4ah uses 10cells. The 6ah uses 15cells. So if it is the same cells in the 2ah as the 6ah then the 6ah is going to be able to output 3 times as many watts. But this is only true because we are talking about a bunch of batteries all made by Ryobi. So the off brand batteries he ended up using probably have lower quality cells and the Ryobi 4ah batteries might output more watts than those 6ah batteries. But they worked so does it really matter?

[@DadItYourselfDIY]

Yes, they worked.

[@bradrandom.2170]

To many cordless what one works better

[@DadItYourselfDIY]

Actually there are only three available in the US. I've only tested the Ryobi, but I would assume similar performance. The driving force would be what battery platform you are invested in or want to invest in.
