Side by Side Comparison of: Arnold vs Maxpower vs Arnold Corporation vs Oregon

This saved my front lawn!!! It really tore up the grass but within a couple weeks my gras was stronger and greener than ever.

Wow I can't believe it worked so well

On my Honda mower, I have to pull raking lines out further or they will not dethatch my lawn. They need to be a little longer than the ones that are provided and sold by them.

Was dreading raking the yard again this spring, tried this product and must admit worked really well..

WOW! This worked great on my LawnBoy 21" electric start self propel mower, cleaned out most of the 10 year built up thatch.

Way better than dethatching by hand!On my Craftsman mower with a height setting of 1-8 I had to set it around 3-4 and mow over the area then go back over again at 2-3.Starting the mower, luckily an electric start, I had to either lift the deck up by pushing down on the handle bar or raise the deck then lower it to get it to start since there was just enough resistance to give the engine problems.

This is awsome. I bought a seperate cheap mower ans left this kit on for next year. Brought up about twice the grass of a normal cut, after i had already cut to the lowest mower deck setting.

Price was right and this item does the job! If you at all mechanically inclined, then the installation is easy enough and shouldn't be all that bad for those who aren't. Would recommend this to anyone, friends included!

Bought this to dethatch my lawn. Fit my 19 inch Murray mower with no problem. Just be mindful when mowing that you don't stay in one spot for too long because it will leave a circle in that spot. So when you go to turn the mower off make sure to keep moving and not just stop in one spot and turn it off.

Instructions were clear enough, though it would be nice if they specified which side of the blade goes down. It took a moment of three dimensional thinking to see how the spring fit correctly, and then ensure that it was pointed the right way.
It took all of 3 minutes to mount it up, and get to work. I have my grass very tall, and it's summer, so I didn't get to carried away with using it, I left it high, not touching the ground at all. It did pull thatch out of the brown spots, though, so we'll see how it does this fall when I trim the grass down and get ready for winter.
I have 2 mowers, the old one now has this blade on it, so I won't have to switch out at all.

We purchased this as our lawn had not been dethatched in many years. It was a bit of a pain to put on, but other than than it worked like a charm. Yes we had a couple of bald spots, that would be because we did not realise how the ground rose under the grass. However it picked up a TON of grass. We did have to play with how high to put the blade, Once we fiugred it out it was fine. It is alot of work, and does not work with the bag. Even with a self propelled mower there was alot of moving of grass. We then put on our regular lawn mower blade and drover over the dethatched grass. I raked up the big piles but other than that our lawn mower picked up all of the dethatched grass. We had to empty the bag about every other turn but still much easier than all that raking.
Grass is recovering well and it is amazing how much dethatching this did.
Read several dethatching directions and play with what level to leave your mower. Do not stop between unless you kill the engine. WOrked like a charm. Not sure what the negative reviews are. Guess they did not read the directions.
Our tines did not break. We can tell they were used but no issues at all, except we will not wait 10 years again!

These wear out fast, but do a great job. I usually get just over ½ acre out of a pair. Easy to install and change out, and they really get rid of all the thatch from the previous year.

Exact fit for my worn out blades

the best seller and product

Exact replacement springs for my Arnold power rake. They bolt right up and it works as good as new.

This is the best invention ever to go on the end of the blade to thatch your lawn in the spring instead of scalping it with a lawnmower blade. It clips all of the runners that have grown during the previous summer so the new ones can grow freely.

I have a zoysia grass lawn. The only way to properly prepare it is to strip the old thatch from the yard. Only then will it grow without showing the dead thatch every time you mow it afterward. Besides it grows much healthier as well. Burn through a set or two of these each year but it's worth it.

I like my de-thatching blade. I use it once a year, right before re-seeding my yard. I can change the blade myself. It was a bit rough on my lawnmower, but I just took it slow and it worked just as I wanted.

Really enjoyed this thatching blade. Easy install and effective product. My lawn is uneven so it missed some spots...

What can I say, but it works!

I loved this item due to easy to use.

I will start with the results It does remove thatch, but not in areas of my lawn where the thatch was thick.In another area where there was so much crab grass that I wanted to get as close to bare dirt as I could this blade was helpful. I set my mower to the lowest possible setting and it removed a lot of my grass.I think that this is the type of product that is useful once a year to keep thatch down, but is not the product you use the first time you need to dethatch.Here is how I used it1. I mowed as I always do before I installed the blade.2. I then moved the lawn one setting lower again before I installed the blade.3. Finally I installed this blade at the same level as step 2.4. I made sure to mow the area with the blade more then once in a different direction.I used the bag attachment for all steps.It is vital you follow these steps. This blade will not move your lawn very well by itself. I tried using this blade for all the steps and it not only did not work, but left more grass clippings on my lawn then I would have had with the standard bladeOther noteI have a husqvarna push mower and this blade was very easy to install. I did not even need all of the adapters as it fit the same way the regular blade did.

The blade did exactly as advertised, I removed several bags of thatch and debris from the yard. I did have to grind the center hole on the blade slightly to fit my Craftsman mower. Other than that, very easy to use...just be patient. Start with the mower about one to two positions higher than normal, then work your way down. Helps to have a dry lawn and go slow to keep the blade spinning fast.

not the same as a power rake, but does the job, eventually, and is much cheaper.

Works exactly as advertised. Was easy to install, and did a great job. I wish it were a couple inches wider though.

It worked. My yard really needed some work. My yard looks a bit messy now because it really brought to the surface alot of dead grass. My suggestion is to cut your grass short and bag the clippings before you use this dethatching blade. You will be doing a good bit of raking of old dead thatch. It will leave bare spots on your lawn when done. Be prepared to loosen the dirt and plant grass seed.

Something I have needed for years, This was the time to get it. Great price, came with several different washers so that it will fit almost every lawn mower. Works great de-thatching, will make re-seeding and fertilizing my yard a breeze. Best purchase I ever made.....

If you want to cut off your grass all the way to the ground, remove the dead grass, rake, and reveal the soil, this blade is for you. My purpose is to overseed my lawn, so I needed this blade to remove my old grass and reveal the ground. This blade will take everything off, from grass to weeds and dethatch as well. If you just want to use it just to rake a dead grass leaving your grass look good this blade is NOT will not work for you.

These do a pretty good job, but they wear out really fast. 7500 sq ft lawn will require 2 sets.

Works great,very little adjustments in height for push mower. Was shocked how well ripped up thatch. Have been using them for about 15 yrs now.

Good idea and quality

Added to the front of preditor mower, helped with routing blackberries into blade.

I like these replacement units. Not sure of any value comparison but the cost seems reasonable, and the quality was better than the units they were replacing, so I'm happy. Packaging was commercial grade, and product was shipped on time. I will order again next year

These things help quite a bit to take out thatch. Will wear down after single use on a large yard but for the few dollars that they cost, well worth it. Saves a lot of time over manual de-thatch rake.

It didn't fit my Craftsman at all. I was able to use it on my Toro, but it was only close enough of a design that I could nervously use it. The Toro would not adjust down far enough to make a sizable contact to the layers of thatch, but it contacted the tops enough to "clean up" the yard. After two passes there was still a large amount of thatch left - enough to keep new seeding from getting to the soil. I still give it a 3 because just common sense said that it cannot work as assumed within the description, and it did stay in the ballpark to what I thought it could possibly do. If you wish to simply clean up a lawn without serious de-thatching, then I feel this blade has at least a much lighter "bite" than the steel tong blades. No questions required on this item. You have to take your chances of if it will work on your mower, then look closely at the design and realize just what it can and cannot achieve.

As a mowing/mulching blade it is pretty good, as a dethatcher it is not very good. It really just tears up the grass, however, after discovering this i used it to intentionally scalp an area where i wanted to plant new grass seed and it was really great for that purpose.

Somewhat works. You have to change the plastic ties very frequently and lower the blade to the point of scalping. And it seems to miss the low points of the yard.

The blade worked ok. however it vibrated so badly it shook the cowling off the mower after 20 minutes.Perhaps I could work on balancing the blade over the winter.

I had the same problem as others with my 3-year old Craftsman mower! It won't fit on the Craftsman star-pattern mount, so you're forced to use the included adapters and washers to get it on. But apparently using those washers doesn't mount the blade on there perfectly leveled or balanced and it causes the blade to wobble around and the bolt will eventually snap and the blade & washers will come flying out from under the mower!The first time the bolt broke it sounded like I had run over a rock, so I lifted up the front wheels like I usually do to let rocks out and the blade went SAILING across the yard! I found the washers directly below the mower, the blade was about 10 feet away, and the bolt head was nowhere to be found. Luckily I was able to extract the broken portion of the bolt with a pair of pliers. I thought maybe the bolt broke because it was just due to be replaced, so I went to the parts store and got another bolt (grade 8 steel) and tried again. This time after about 3 passes the whole mower started wobbling and I could tell the blade was probably loose, so I immediately stopped it and looked underneath and sure enough the bolt head was literally hanging on by a thread! I pulled the head off with some pliers, removed the blade and the rest of the bolt, and went back to the drawing board.I figured I'd try it one more time, but first I wanted to see if the blade was properly balanced. I bought a sharpening/balancing kit from HD and it turns out the blade was slightly off balance to one side. I checked my original blade and it was even more out of balance, but I think since I'm able to mount the original blade to the star pattern mount it isn't as critical to have it perfectly balanced. I used a grinder to remove some material from the heavy side of the blade until I got it perfectly balanced and then I reinstalled it using the following method: THICK WASHER-BLADE (with 3/8" adapter)-THICK WASHER-LOCKING WASHER-THIN WASHER (used from previous blade)-BOLT. With this assembly, and with the blade perfectly balanced, I was able to finish the rest of my yard without any more incidents. It actually did a really good job at dethatching and scalping my summer bermuda grass in preperation for the winter overseeding with perrenial rye.So the bottom line is that if you have Craftsman mower, or any mower, with a star-pattern mount which doesn't fit the hole in the center of the blade, you MUST make sure to balance the blade before using it! You'd think they would come perfectly balanced from the factory, but apparently not. Also, you MUST use one of the included thick washers on each side of the blade to hold it steady and keep it from wobbling around. Also, make sure you tighten it just about is tight as you can. I used a breaker bar and probably overdid it, but I just wanted to make sure the blade was held tight and wouldn't be allowed to wobble and break the bolt again.

It worked OK. Did not pull up all the dead grass like the old metal one did. This also seems to cut alot lower than the standard blade so just a heads up on that.

The prouct is good but I was expecting more,but not the blade,it is as promised,I wanted something that would chew up the lawn a little more.

This may work ok if it will mount to your mower. I have a Honda Masters series and the 2 mounting holes are not big enough for the bolts. I'm not sure if the Masters is different than the consumer, Harmony series.

As far as the blade and spring/dethachers, it appears it would work great as long as it's set at the right height. Based on some reviews, some are trying to cut into the soil. I have both Tiff 419 and St Augustine and I can see it working fine in either, adjusted correctly. Don't expect it to hand pick everything you don't want on the ground, but it gets a lot more dead material than you can with a plain blade.

3 stars because the quality is there and after using another blade to do what this one was supposed to, I can definitely see where this one could be more efficient, again,at the right height, and not expecting one pass perfection. Knocking 2 stars off because it is not as described as far as application. I might could have made it work if I took a chance and damaged the 2 bolts, but I change blades configurations often and don't want bunged up bolts.

Didn't work with a star shaped Husqvarna, thought I could make it work and gronk down, don't do that, I then thought I screwed up my whole lawn mower since it was stuck on there. It worked for about half the yard, did its job for that half, but then didn't move with the motor, the issue was the middle hole, the Husqvarna has a star shaped middle. Happy that it only cost me a little to try it, had that scare about ruining the lawn mower though.

Better then the plastics ones

I used it for our lot and need already a pair of new springs, that's not very helpful!

I ordered the springs as a safety measure after ordering the Maxpower 330100 to de-thatch my St. Augustine lawn. I am not going to use the blade, so the springs are simply not needed.

Replacement spring for Arnold Power Rake Dethatcher. You need a couple of these, since they wear out rather quickly.

I'm giving 2 stars because I am able to use it as a back up. This product stated it was for dethatching, I made to passes over my yard and it barely did anything. Second complaint I had is that the "universally" feature of this blade doesn't work well with Honda mowers, that may have contributed to why I didn't have great results with blade.

This thing was better at scalping the grass than dethatching it. I tried all combinations of ground and engine speed. If you must dethatch, save your money and rent a proper dethacher with blades that rotate around a horizontal axis.

I bought this to remove thatch from my lawn. All this did was cut the grass with a chopping pattern. No thatch was removed.

Blade cleaned a lot of dead stuff out of the grass, but it left a LOT of the thatch there. I should have got the kind with metal tines. I started at a high setting and worked my way down.

I really really wanted this product to dethatch my lawn like the product description said it would. However, it ended up being a pretty good mulching blade, but ineffective at dethatching. I used it on a Troy Bilt TB 230 push mower. I tried it at various deck height settings. At deck height number four, I could not tell that a detaching blade was on the mower. At deck height three, it cut my grass very low. But very little of the thatch was lifted up out of the grass. At deck height two, the dethatching line on the blade scalped my lawn completely leaving nothing but dirt. I suggest using a traditional dethatching tool or attachment that has thin metal fingers to do the dethatching work. I cannot recommend this product for dethatching.

Makes the lawnmower vibrate & shake, poor quality cut, and short de-thatching forks. the "tines" break at high settings, and instructions suggest to use for scalping. wish I could use for scalping, that is the reason for purchase but have to keep the lawnmower on some of the highest settings to keep the tines from breaking. tines end up being more expensive than the blade after just a couple of uses.

I could not get this to fit my Greenworks electric mower. In fact, the instructions recommend that you don't use it with any electric mower, although it then concedes that you can go ahead and try if you want. I don't know what the downside is to running it on an electric.

Two stars because even though I couldn't get it to fit, it otherwise appears to be well made.

As many have mentioned, I had to enlarge the slots in this blade to fit my mower. More importantly the times weren't long enough to reach the thatch layer. I washered the blade down and lowered the mower to its lowest setting and still all it would do was chop the tops from the existing grass, never got to the thatch. This is just $12 worth of landfill for me...
This was a Honda mower, fwiw.

This was an old review from 2014 but it rang true for me:

"Don't waste your time. All it did was strip all the grass down to the dirt. Started at the highest setting and worked the level down until it just made contact with the grass, the next setting shredded the grass, but didn't touch the thatch. The next setting ripped the grass and the thatch from the ground."

It did a better job of cutting my grass off than bringing the thatch up.

Here's a few reasons as to why it was unsuccessful and did damage:

1. At a high setting it didn't shred my grass, it also didn't touch the thatch
2. My grass wasn't wet, but it wasn't bone dry. I think bone dry might be best.
3. We just purchased the house and the lawn is complete garbage to start with.. thin grass, lots of creeping Charlie, & moss... it's not thick grass. I think if it were thick and healthy we might've had luck.
4. I hand rakes my small front and took up 6 garbage bags of thatch. I know the thatch in the lawn is super thick and compressed... it hasn't been dethatched in probably 20+ years.... because it's compressed and thick this tool didn't work.

If you're feeling out of luck get a manual dethatching rake. Picked mine up at the thrift store for a couple bucks.

After dethatching, aerating, and overseeding I'm going to give it a year to grow. I'll try this tool out next year and see if they're any changes... it did fit my 21" Murray mower just fine.

A lot of reviews are super positive... making it hard to believe my experience was so horrendous!

Doesn't work on my mowers, the spring doesn't touch the ground, even at the lowest possible settings.

I was hoping this would work but it didn't. I set the deck high to start and tried it. I lowered it and tried again until it touched the grass. It pulled up more live grass than thatch. It actually didn't pull up very much thatch. It ended up shredding the existing blades, leaving ragged, damaged ends. Luckily I only did a small area but I'm worry that it may have damaged it.

It also says it is recommended for gas mowers. I have an electric mower. It says you can use it as long as you keep a constant speed, which I did.

Had to place so low it basically tore up my lawn. Didn't detach squat.

After an 1/4 acre I have to change it !But the result is ok!

Not the greatest quality. Spring breaks after about 20 minutes of use. Do not have the mower set on a high RPM or low to the ground. They do work however.....

The tines are way to short to mow at a healthy height. In order to collect anything I had to cut my grass much shorter than I wanted. With minimal thatch collected. Very disappointed. I will be renting a normal power rake to do the job the right way from here on out.

Did not pull up any thatch in my yard even with mower at lowest setting. Back to doing it by hand.

Installed as instructed and at first I tried my mower raised to the highest setting. Nothing happened to the grass. Next I lowered it one setting and it scalped my lawn and did absolutely nothing to the thatch below. Don't waste your time.

Only buy this if you regularly cut your lawn 1/2" high. I kept lowering the deck and it never got any thatch. All it did was scalp my lawn. I had to modify it to fit my lawn mower so I just threw it in the recycling bin.

If you want to tear up your lawn, then his will work. The lines are too short so the deck has to be very low to dethatch so it cuts the grass about 1" or so long. I have a nice line that is now terrible in my lawn.

My Husqvarna self-propelled 21 inch mower cannot use this dethatcher. My Husqy uses a 5 point star shaped connector hub; this dethatcher can't be adapted to this attachment.

You have to put it together yourself and the instructions suck and it's impossible and mine broke just trying to install it. What a waste of money.

This product gets one star. WhenI opened the package, all parts were there except the two bolts needed to attach the springs to the blade. And the directions aren't directions at all, they are terrible. NOT universal!

This is supposed to be a UNIVERSAL blade,, The spindle hole is WAY to small to even fit a Toro 22" walk behind mower. Missing parts, Doesn't FIT, Crap customer service. This is a purchasing NIGHTMARE.

A real piece of junk. They give you a hand full of adapters, not one worked on my Snapper mower. If your mower has a couple of dimples to help hold the blade in place, do not get this. It just spins and wears down the dimples. Would not recommend this to anyone I wanted to keep as a friend.

Don't waste your time. All it did was strip all the grass down to the dirt. Started at the highest setting and worked the level down until it just made contact with the grass, the next setting shredded the grass, but didn't touch the thatch. The next setting ripped the grass and the thatch from the ground.

Product didn't fit the thatcher blade that I also purchased.

Mine broke or wore out on the first outing. They didn't last for a 1/4 acre of lawn.

I bought these as a "Bought together item" for a rake/mulching blade. They will not fit the blade. If you buy these be aware that the blade must be drilled and you must buy the mounting hardware separately, The product does not include mounting hardware.

These springs, compiled for bundle purchase, do not fit the Arnold 21" mower blade they were bundled with.

Awful. Did not fit my mower

the springs are not made very sturdy...they wear down very fast. I used to purchase these for years and one pair would last all spring. I guess when we send everything to China to be made...this is what we get....poor quality!!
