I’m in the middle of raking up all the thatch that was created using one of these blades. I am on day two of raking up this mess and looks like it will be possibly day three. Tried the lawn mower with bag, but it filled so fast it was too time consuiming emtying it al the time.
Furthermore, the blade didn’t reach deep enough into the thatch. So, after I rake up this mess, I get to do it all over again!.
The spikes create alot of fluff – but I would say a good third of it is the grass it ripped up – basically the lawn got a very short hair cut and maybe half the thatch came up.
Do yourself a favor – hire someone to do it!

Was very pleased with the speed of delivery. I couldn’t find this item anywhere locally. I guess no one de-thatched their lawn here in Florida. Antway, the product worked great. I ised it about 1.5 weeksago and the lawn is greening up nicely. I expect in two weeks in will be where I want it to be. Thanks for mking this product available to me……

Product worked great for my small lawn. Picked up tons of thatch and only went over the lawn once. Went on and off the mower really easily. Highly recommend this product for anyone with a small to medium size lawn. Now hopefully the new seed will take…
Only hiccup was when the self-appointed “lawn god” next door decided to come over and say “You know that’s not how you mow, right?” (Yeah, buddy. I know that’s not how you mow…) When I asked him if he knew what de-thatching was (he didn’t), he simply tried to change the subject by telling me that I went over to “his” side of the lawn… I apparently should’ve known, since he’s been mowing up to a certain spot for years (I just bought the house…).
So anyway, that’s a long way of saying that thatching is an ugly process. Beware the ignorant “lawn god” next door…

My lawn probably never had been de-thatched and I was to lazy to rake de-thatch the whole thing. This blade worked well for what it is. I didn’t go to low on the mower so it wouldn’t destroy my lawn and it still pulled up most of the dead grass that I had. I did have to go over with a rake to get some of the tough to get stuff but if you are somewhat lazy like me and hate raking this is definately the way to go.

This product is amazingly simple & works just fine w/ a few tweaks, per within.
However, a slight downside is that both of the spring tines broke after exactly 1 year & 6 uses (shucks). Found some ersatz replacements @ the local landscape supply for much less than offered here, so no heartburn overall.
Caveat: With JUST the Arnold #490-100-0012 Dethatch blade installed, I found that thatch trimmings were definitely NOT clearing-out from underneath the mower’s deck. They would just build-up, spin around & actually lift the whole deck UP, until it became very difficult to push at all (at this point, every wheel was lifted slightly off the ground & the side discharge chute was clear/wide-open). Was not a great situation ….
Background: My aging 20″ Murray pusher is a tired ol’ beast & lacks much torque, so I had to get real creative when using this product. Believe it will benefit all users, however.
Solution, part 1: For now, just forget about the grass/clippings bag – take it off & throw it aside.
Sol’n, pt 2: Add a 2nd blade. Be sure it is a normal grass-cutting HIGH-LIFT/mulching type. Set it up in a cross-pattern (aka: “X” configuration) on TOP of the Arnold Dethatcher, if possible. If not, be sure to separate the blades w/ a large flat washer, because the Arnold Dethatch blade is concave on the bottom face!
Sol’n, pt 3: Use a low idle speed – as low possible (was kinda tough w/ the ol’ Murray ….. frequent stalls, etc). Walk at a fast pace, & don’t slow down or dwell on any spot.
Results: Worked like magic after using these tricks & then fooling-around w/ various wheel heights. Thatch trimmings were thus flying out the R side, landing 6-8 feet away. Never looked-back & now we’re all smiles. Lawn has never looked better, either …..
Good luck & do hope ‘dis helps a bit !!
Regards,
