It is advertised as if it does, but I was unable to make it work without modifying the plastic spacer/washer that is part of the normal blade assembly. Since i'm pretty sure this is not sop, I can only wonder if there's some trick I missed, or if this is just situation normal all F'd up. At any rate the pitiful few instructions did not make it clear how it was supposed to work and the included hardware seemed inadequate to get a good fit on the ryobi assembly which is a bit unusual. So a bit of hacking on the nylon washer and i was able to get it to work without making the washer unusable on the regular blade.
Without knowing the specifics of your set up, I can only assume you have a two blade tractor which may or may not work with the included hardware. I found the term "universal" to be deceptive, and had to rework a plastic spacer/washer to accomodate the blade on my ryobi mower, even though this dethatcher was listed as if it fit my ryobi. If you are at all handy and ready to make the adjustments that may be needed you can probably get this to work Even if the blades do fit the shaft, they won't completely fill in the 42 inch cut, so multiple passes would be necessary.
this is a "universal" blade in name only and I had to make major adjustments to the mounting on my ryobi mower even though the blade was specifically listed as if it fit . In my opinion the blade is deceptively labelled, and while it does come with extra spacer washers etc it is not necessarily a perfect fit. The basic blade is functional, but beware that you may need to play with it a bit to get it to work
I never got around to using mine. I would snug one or both bolts by hand so you can tap on the ends of the dethatching blade to center it up and then measure the gaps in the slots to get them as close as possible to equal as you tighten the blots. The viberation will be minimal. The tines draging across the grass will cause most of the vibrations. I look at your Honda HRR2167VKA on youtube, it looks pretty robust. Again if you can tighten the dethatching blade within 1/8 inch or less of equal it should be fine. It's up to you if you want to try and center up the blade. I hope that helps, good luck.
The blade comes with several extra washers that allow fitting a variety of blade attachment systems. I have actually used this blade along with my regular whirlwind blade so as to better bag the thatch that is removed. Be careful not to lower it too much on your first trial because you can easily fill the bag in a single run across the yard.
