Works Great, provided...

I was skeptical when I bought this due to some other reviews. This exceeded my expectations and will do the same for you, provided you use your head. This type of thatcher needs to be used with some common (uncommon?) sense. You need to install the plastic thatcher's on both ends (they are installed on one side), if you do not, you could cause engine damage as noted in other reviews. 1- install the blade and raise your cutting height slightly (so you do not scalp) 2- be prepared, depending on how much thatch you have; you may pull up 4 to 10 times your usual number of bags 3- go slow - lots of pull on the motor. 4- I did an initial pass, a second pass at a lower level and a third pass at the same level to pull up any remaining thatch. This blade worked better with less scalping than any thing I have used over the years. PS - if you have a lumpy or uneven yard, you may not want to use a thatcher blade... Good luck

More frustrating than effective.

[????Why can't reviews be formatted with paragraphs????] * * * * * I bought this last year to try to boost the miserable performance of my "Craftsman Professional 190cc* Variable-Speed Rear-Wheel Drive Mower." Well, I'm not sure anything could help that mower produce really good results. This certainly didn't. * * * * * The idea is neat - the stiff plastic strands 'rake' the lawn as you mow, sort of like a lite-duty power rake. However, the plastic tines fall out almost immediately. I cut a couple of swaths with good - I wouldn't say 'great' - results, then noticed lower performance for a few more passes, then checked. 2 out of 3 plastic tines on each side were missing. Same results after replacing them all twice. The replacement plastic tines can get expensive, too: each replacement pack costs about %25 as much as the blade originally. * * * * * The problem is that nothing really holds the plastic pieces in - they just get bent in half and forced through holes in the blade, and come out just as easily. If I decide to use it this year, I'll try to rig up some way to keep the plastic wires in, then it might be worth it. Of course, the plastic parts wear out, too, so spending a lot of effort to keep them in just means re-doing that effort at each frequent replacement. * * * * * In all, I suggest getting a metal-tined power rake attachment.

Works like a charm


For those posting negative reviews must not have a clue...This does thatch & bag, as long as you follow some basic common sense and instructions. Adjust the height properly and it wont scalp your lawn. It thatches, rakes and bags all at the same time. Works almost like magic, took less than two hours to thatch, rake and bag after two passes, so just twice as long as it takes to cut it. This blade fits my Husqvarna with the "star" on the crankshaft when the Arnold generic blade would not.

does not detach very well


I have a 50' x 50' front yard. Mostly Bermuda grass with a mix of weeds, crabgrass other unknown grass . Sometimes I mulch mow it and some times I bag it when it's has grown to tall between cuttings. I can't mow the Bermuda to low or it thins out and gets over taken by the other growth. I guess it's early in the spring. Bermuda goes dormant in the winter. This would be the second cut since it turned green. I get splotchy areas where the grass does not seem to grow well because of a layer of dead grass that seems to choke off grass growth.
I have a dethatching rake that becomes exhausting work after a few minutes. so I thought I would give this a try. FAILED to preform as I had hoped
I cut it with my original blade first. Then I installed the dethatching blade. I adjusted my mower a couple notches lower. I think I would have had the same results with my original blade. I adjusted it lower and it scalped the grass to the dirt. I reset it at about 1/3 up. Mowed the entire yard. The rakes did not even touch the areas I was hoping to clean up. I had to manually dethatch it with the rake.

Maybe the plastic rake teeth on the blade helped stir up the clippings, there by helping them into the bag. ???

I presume they quit selling the ones with the metal spring type rake because they could be dangerous.

Does the Job


The Craftsman 21" Advanced Dethatching and Bagging Blade performs as advertised. It takes some experimentation to find the correct deck height, however, that was expected. It's obviously intended for smaller jobs which is what I needed. Mounting hardware was complete and I am using it on my Husqvarna push mower.

The best 21" Advanced Dethatching and bagging Blade you can buy for lawn cl


this is the second blade of this type I have purchased. It works great and will last a long time and you can replace the dethatching line. The only place you will have to rake is where the mower can't go!

Dethatching Blade for my lawn mower
