Rated 4.4 out of 5 by 35 reviewers.
Rated 5.0 out of 5.0 by JD Thatcher is great This product is extremely well built and definitely worth the price of just over $200. I use it with about 50lbs of weight (2 concrete blocks - see photos) and it works great. It took me 1 hour and 56 minutes to assemble and another 15 to 20 minutes to make the tine height adjustments. I have attached photos in the "transport" mode and the "thatching" mode. The only criticism I have are the less that clear assembly instructions. I recommend you measure the bolts and read the instructions carefully as you assemble it. DO NOT go solely by the pictures, because they often have the left and right mixed up. As someone else has pointed out the written instructions are very accurate. The pictures are often the wrong image. All in all Home Depot and John Deere have hit another home run. April 28, 2013
Rated 4.0 out of 5.0 by Better than raking This product actually does the work as advertised. I had some thick thatch and had to stop on clear the tines a couple of times. I would recommend this to anyone that has a tractor. Set aside at least 3 hours to put the Thatcherator together because the directions are not very clear when it come to what bolts you need to use.

Rated 4.0 out of 5.0 by Made in the USA! Why Home Depot isn't capitalizing on this best selling feature of this unit is beyond me. The quality of construction is great, and the nuts and bolts are even SAE (NOT metric). Most of which are 1/2" or 7/16". If you are used to instructions with a picture for each individual step, they may have you scratching your head. While the pictures are not the best, the written directions are VERY thorough. Thanks to Home Depot, you can view the instructions (see the "More Info" tab) prior to purchasing to determine if this is something you could handle. Once assembled this unit requires some minor adjustments since all lawn tractors are not made equally. These adjustments are very straightforward but will require some observations on your part. For example, if the tines are not reaching the ground you'll have to lower the tray and vice versa. I did have an issue with a missing piece of hardware. I called JD and spoke with someone who spoke english right away! The part was FedEx'd to me very quickly and I was de-thatching my lawn within a couple days. I had yet another issue with a hole not being drilled in the correct location. The hole for the lift lock pin in the lift handle was drilled too high. When I pulled the lift handle to the side to raise/lower the unit, the lift lock pin caught the top of the hole in the lift lock plate, preventing me from raising or lowering the unit. Drilling a new hole in the lift handle slightly lower than the original solved this issue. Once assembled this unit worked great! I was amazed at how much thatch had accumulated in my lawn. If it weren't for the missing part and having to drill a new hole in the lift handle, I'd have given this unit 5 stars. April 2, 2012
Rated 3.0 out of 5.0 by "Some Assembly Required" Very disappointed to open the box and try to get this put together. Directions had horrible instructions supported by nearly unintelligible photos accompanying them (tried to use photos to make up for lacking written instructions). Once cobbled together (requiring some nifty dexterity), the wheel fell off initially into a one acre project requiring a long walking inspection to recover the missing lock washer and nut. Guys, revisit the lock washer/nut idea and find something better, the wheels either lock up or fall off. Finally, the thatcherator was attached to the back of a JDeere mower/tractor. The directions for installation were for some other piece of equipment (important in measuring thatching height). Other than that, it performed (1x) as expected. March 25, 2014
Rated 4.0 out of 5.0 by Solid product that works well It is now almost effortless to de-thatch my acre of lawn. Assembly took 1 1/4 hrs but then I went back & re-adjusted the depth so say one & a half hrs total. Some of the assembly pictures do not clearly show the details that they should, but, if you have experience with such assemblies, you will do fine. If you are inexperienced or do not have the right tools, the assembly of this product will frustrate you (that is the only reason I didn't give it 5 stars). May 13, 2014
Rated 4.0 out of 5.0 by Better than average quality .........at a price! Once this attachment and I get properly acquainted, I believe it will do the job. It lived up to its reputation as being miserable to assemble....I had a Home Depot assembler put it together and I still went home with a ziplock of extra miscellaneous parts. April 21, 2015
Rated 5.0 out of 5.0 by Does the job! Never realized there was so much accumulated thatch on my lawn. The thatcherator is easily pulled by a John Deere X320 and kicks up thatch and acts as a spring tooth harrow. I reseeded the lawn and now have beautiful green grass. Take time to completely read the instructions and use photos from JD website before assembling unit. Once adjusted, tighten bolts snugly except for the lift lever. I have used the thatcherator three times with no problems, and plan on using it each spring and fall prior to overseeding. When used with the JD plug aerator, my lawn looks like it has been professionally maintained. November 11, 2014
