    Alright for the price but not as good as an actual machine
  

*by F***Y on Reviewed in the United States on September 4, 2022*

First, I do not recommend using this on nice healthy green grass. It is very hard on the lawn and will burn it. Rent an actual dethatching machine. Use this only on brown or dormant grass. That being said, this blade actually worked alright. It didn’t pull up 100% of the thatch but it got a lot loose which allowed me to rake it up. I could have probably gone slower or made a 2nd pass if I wanted to get more up. I was originally going to get the maxpower blade but that has a circular hole. If your mower uses the bow tie / 4-point / star bolt pattern blade attachment/adapter, spend the extra few dollars and get this one. It fit perfectly. I also bought extra springs but I didn’t have any problems with the included ones breaking over 2000sq ft. I also have a 21" mower and this worked just fine.

    Don't buy the springs.
  

*by L***H on Reviewed in the United States on January 13, 2023*

I needed to dethatch my yard in Justin, TX so I ordered this blade on Amazon. Blade delivered on time and was easy to attach...however it did not work well for my lawn. I did not lower the blade more than a 2 level so it may have worked if I had lowered it more but was afraid it would tear up my yard more than help it. So the product itself may be fine but in the description (third or fourth point) says it does not include the springs but it does come with them. Based on description I ordered the springs. Now I have to pay shipping (a bit north of  $3.00) to return them....

    It works as described
  

*by S***T on Reviewed in the United States on October 18, 2022*

Prop mower up partially on its side carburetor toward ground & disconnect spark plug wire.  Wedge 2x4 to prevent blade from spinning, remove bolt and remove old blade noting which side down toward grass. Wire brush mating surface to ensure new blade sits flush on shaft.Application of installation on a spare 28-year-old Craftsman 3.8HP; the bow tie shaped adapters were not needed. They fit into the blade but protruded and prevented the blade from sitting totally flush and tight on the engine shaft. The two round cylinder-shaped pins on the engine shaft did align into the blade slots with a few taps of a hammer.Reuse the old bolt and washer along with selecting the correct size provided additional washer with correct center hole diameter and tighten thoroughly.Adjust wheels down on pavement so spring ends are slightly above ground or touching the ground. It will take a few tries to get your adjustment correct after testing, try both low and high engine RPMs. Stop and verify blade if still secure.  This blade will bag or discharge.I used it to scarify in a few sections to remove dry dead weeds to prepare for reseeding.The spring tines did noticeably wear down a bit after 20 minutes of use, but it did the job well.  ** Be sure to wear eye protection! **
