NEW Accessory for the RYOBI Dethatcher | Power Raking or Scarifying | 2021/35

I recently received a Ryobi Dethatcher Scarifier from the UK via Amazon. This unit is coming soon to 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.
Unlike the upcoming US version, the UK version does not come with any accessories. shipped standard with the scarifying (verticutter) blade, I wanted the power raking blade, which unfortunately was on back order for some time. After three months of waiting it finally arrived, and I could not wait to try it out. Coincidentally the timing was perfect for my fall season dethatching in preparation for over-seeding, fertilizing, and top dressing the lawns!
I was able to dethatch/scarify my entire front yard, which is a little over 1,500 square feet, on one pair of 6ah batteries, and two pairs of 3ah batteries to finished the boulevard strip, side yard, and backyard lawns.
The power rake is very efficient, easier to use than the scarifying blade, and does not dig as deep, so the unit works a little easier, which in turn gives you longer battery run times. This is my go to blade now.
I was also able to run the unit with the back flap in the up position to see if it made a difference on the performance. It definitely spread the thatch out, and made it easier to pick up with the bagging lawn mower, but there were definitely some times when I was showered in dirt and grass in some of the drier impacted areas.

You don’t have to have the door FULLY OPEN. I think you will find that having the door open 75mm - 100mm open you wont get yourself a “grass bath”. I modified my lawn sweeper to stop the grass/leaves from shooting up and covering me with grass etc. Great video. 👏

You will blow it up since this unit is only an 18v unit yes it has two 18v batteries no it doesn't use both at once the red key plug has an arrow on it indicating which battery is being used. It holds two batteries but only runs on one 18v. Just like the Ryobi 18v lawnmower that's only 18v and holds two batteries and has the same res key plug one or the other.

Great review! Love, love, love Ryobi products. It's the only brand we use on our lawn. Just got 2 new toys: Conversion kit for the rider and the dethatcher/aerator. We have Bermuda grass in the south. What level do you recommend for properly dethatching/aerating Bermuda grass? We have a lot of mulching debris that is smothering the grass.

[@DadItYourselfDIY]

I drop it all tgecway down, but I have cool season grass. Start high, and keep testing it until you get the results you need.

[@notta3d]

I want one of these so bad because the corded versions seem like a nightmare dealing with that cord. With that being said the price of the batteries for this Ryobi are outrageous. Great video though.

[@DadItYourselfDIY]

Batteries are expensive. But it's worth not having a cord. I chose this because I had the batteries.

[@pistol2556]

Great video. I bought the Sun Joe dethatcher and it was a nightmare with the cord. I returned it. I bought the Ryobi but have yet to use it. I know it will be much better to navigate.

[@DadItYourselfDIY]

It's a blast!!

[@leightri]

You did a great job. My concern is that it looks like Home Depot sells the Ryobi for more than $520 (including 2 batteries). For me, that's too much $ for something I will use 2x a year. Either I will buy and split the cost with a neighbor, or buy a corded tool. Corded seems a much cheaper option.

[@DadItYourselfDIY]

Corded is definitely cheaper, they need to offer a tool only version for folks who already have the batteries.

[@Lundbakk]

you dont like to use the bag on the ryobi scarifier, but then you use the lawn mower to pick up the debris, into the lawn mower bag. Isnt that the same thing? i get that the lawn mower is alittle bit bigger, but still think u could use less time overall with the scarifier bag. just keep a wheelbarrow close by.

[@DadItYourselfDIY]

The mower bag picks up 4x as much as the scarifier. I rake the yard and pick most up by hand, and use the mower to clean it up.

[@1babydario]

Reviews in the United kingdom say that the plastic wheels break off after a couple uses I hope ryobi fixes these problems before releasing in the USA because they are dragging the release date it's reaching 2 years almost.

[@DadItYourselfDIY]

I have no issues with the wheels, in most cases when a wheel breaks its a user issue not a product flaw.

[@troyhenry3267]

Do you regret getting the cordless battery model ? If not , does it provide enough juice and run time for your lawn? my front lawn is about 1800 -2000 sq feet, and i'm wondering if the battery version would do me just fine?

[@DadItYourselfDIY]

I can do my whole lawn, about 2500 Sq ft, on one 6ah batteries. I have three batteries, so there are no issues.

[@audireddevil]

great videos. How often would you recommend doing this? Have a fescue lawn

[@DadItYourselfDIY]

I do it in the spring every year. And if I reseed in the fall.

[@kylenunes9401]

How can you identify the different types of grass/lawn/sod?

[@DadItYourselfDIY]

Sod should be easy, when you purchase it, they tell you what it is. The other is cool season fescue, bluegrass and rye are normally grown in the north, whereas, warm season grasses centipede, st augustine, and Bermuda are usually grown further south.

[@kylenunes9401]

[@MRBLACK1080]

[@craigphillips3154]

My biggest concern would be runtime. How big of batteries (and at what price?) would be necessary to do a lawn of 1/4-1/2 acre? Yeah, an extension cord would be a pain to deal with, but at least you would get "unlimited" runtime and could finish the job without recharging or swapping batteries.

@@DadItYourselfDIY How many pairs of 4ah batteries would you estimate it would take to execute a 1/4 acre yard? I have 4 currently and the 2 that come in the kit would make 6.

That's about 10,000 Square Feet. I get 2,000 square feet out of a set of 6ah. So, conservatively, 5-6 cycles. So hopefully your first set charges, while your using your third set.

My first video about the dethatcher uses the scarifier. kzbin.info/www/bejne/d2SZdGateKllpLs

[@dantebernardini428]

Hey great video. I am very new to this and I just bought one of these. Are the two blades just a matter of personal preference? For some idiotic reason I thought the power rake was for de-thatching and the scarifier was for aerating and then for overseeding. Can I just use one for both? I live in the south and I was going to aerate and seed very soon, but do I de-thatch and then overseed and then just de-thatch in the spring again. Kinda confused and was wondering if you could clear some of this up for me. I am a complete novice when it comes to this. Also, I saw your 40V conversion video and this is something you should really consider marketing and making. I know I would buy one. Thank you VERY much in advance.

[@DadItYourselfDIY]

No, you nailed it. I always use the scarifier blade before reseeding. To call it an aerator is a stretch, if you look at a core or slit aerator it goes significantly further into the ground.

[@Supanova70]

when do you use the scarify tool then?

[@DadItYourselfDIY]

In the fall or when you are going to overseed. It loosens compacted soil and allows for better seed to soil contact.

[@humblerawat]

Are you in Pacific NW area

[@DadItYourselfDIY]

Yes

[@alastairkirkland1580]

Great video, thanks. The difference between the scarifier and the rake - the scarifier actually takes out a level of thatch that you don’t want on your lawn and the rake is just a rake, it picks up all the dead stuff but doesn’t actually de-thatch? Is that the correct way to consider it? So it’s not a case of using one OR the other as you please - as they do completely different jobs? Is that right?

[@DadItYourselfDIY]

I would agree with that. The scarifier is much more aggressive.

[@kellkelley5743]

I hate to disagree, but a scarifier slices the warm season grass to promote growth. If you use a DETHATCHER system, you will RIPP OUT YOUR WARM SEASON GRASS. I know this for a fact. Someone told me to use the DETHATCHER cartridge on my warm season grass. What a mistake. I now have a DETHATCHER system to remind me of a stupid lesson learned.

[@DadItYourselfDIY]

How does the power rake attachment do with the warm season? I could see how the scarifier would rip the tendrils..

[@kellkelley5743]

The power rake is more for fescue. It's more of a DETHATCHER. The scarifier is more of a verticutter. It slices the runners to promote growth. Think of the grass runners like a worm. When you divide a worm, it is now two. Same process with grass with runners. It then starts looking like a tightly woven blanket. It gets more density or denser.it also removes thatch and allows better watering and fertilizer and nutrients to enter the ground, which is good for a healthy root system.
