    5.0 out of 5 stars This is the best yard machine you'll ever buy
    Reviewed in the United States on October 18, 2021
    So, I purchased this item after my boss told me about it. He showed me pics of his usage, and I figured, why not? It was relatively inexpensive, costing about the same as a one-time rental of a dethatcher from the local rental place. I figured if I get 2 uses out of it and destroy it, I'm ahead of the game. Plus, I could use it at my convenience and not have to worry about returning it.

    We take pretty good care of our lawn/yard (it's not perfect, especially in the area that used to have an above ground pool, but we try). It's a larger lot (about 1/4 acre) in our neighborhood, and we mow every week with a push mower. We alternate weeks of mulching and bagging, so we really didn't think there would be very much thatch coming up. Boy were we wrong. We started off with my husband cutting and bagging the grass in one direction, and, as he moved to a different section of the yard, I started with the Sun Joe going in the opposite direction, using the dethatching attachment. I followed him around the entire yard doing this. Because we didn't use the bag on the Sun Joe (see "cons" below), he then went OVER the thatched material with the lawnmower to bag it up - first in one direction, and then he did the entire yard AGAIN in the other direction to ensure that it was all picked up. We were going to use our Billy Goat blower, but figured that would make an absolute mess, so we opted for the mowing route. Total time for about 9000sf - 4 hours. And well worth every minute.

    I should have taken photos, but rest assured that I was completely and utterly dumbfounded at the amount of dead grass and compost-like material that we raised, and it takes quite a bit for me to be impressed by a yard machine.

    Pros:
    - easy to assemble - only tool needed was a Philips head screwdriver (also, make sure you push the angled handle portions of the metal tubes ALL THE WAY into the body of the machine - many review complain about this, but I can see where the issue is not pushing in all the way). The rest of the handle is assembled using large, easy to turn plastic thumbscrews. Very convenient.
    - the height/depth settings are easy to change. Simply push the green t-handle in and move it to the setting you choose. I tried the "0" setting first so as not to damage any grass, and found that moving it to the "-5" setting worked even better and caused no damage. On the areas where we had moss, I moved it to the "-10" setting. Moss no more.
    - works exactly as described and as needed - they're not inflating the value of this machine, I can safely say.

    Cons:
    - the bag. As most other reviews stated, the bag is a joke. True, but we just left it off. See above for how we picked it up without breaking our backs raking.

    Notes: seriously - make sure you're using the right size extension cord. I used a 12 gauge cord at 100 feet and had ZERO problems. Machine didn't shut off, overheat, or otherwise explode. Also, you can use a tiny bungee cord to wrap around the handle to keep it powered as you move through your yard. The angle of the power switch can get a little uncomfortable over time.

    Overall - 5 out of 5. I wouldn't change a thing - even the bag. It would take a REALLY big bag for it to be convenient, and the only other option would be a giant vacuum, so I can't count that against them.

    I wish I could give this 6 stars!

    When I put this together yesterday I was apprehensive. The handle felt cheap. It went together cheap. I know I can fix the handle if need be, but I don't much care for thinking about it when I'm putting together brand new things.

    Once everything was together, however, it felt ok.

    It came with the scarifier installed, so I had to switch that out. It would have saved me an extra trip to the tool room if I'd known it was a 10mm bolt. If it says so anywhere, I missed it. So keep a 10mm socket or wrench handy. Switching it out for the dethatcher was simple and easy.

    Now, my lawn isn't pretty. In fact, I've been fighting with it off and on for about a year now. It finally occurred to me it needs dethatching, so here we are. If it has ever been dethatched, it was a long, long time ago.

    Due to the current heat wave I had about 1 1/2 hours between melting and darkness to take care of business. After mowing the lawn I brought out the dethatcher.

    It's not self propelled, exactly, but it does tend to pull itself forward just by the way it operates. If my lawn were flat I would have had no trouble at all moving it around, however medium-ish dips and bumps would block its progress. I had to twist it a bit to get it to continue. Not really a big deal, and certainly not a problem with the design. Sure, you could maybe trim some of the plastic off the front to minimize this problem, but that would leave exposed quickly rotating pointy sharp things, which is a bad idea. Next time I'll carry a bucket of dirt with me and use this as an opportunity to even out the lawn somewhat.

    The instructions say to walk this forward and go over the lawn in an orderly, once-over type fashion. That's probably the best way to do it.

    For most folks.

    I, however, didn't have much time for such things, nor is my lawn orderly, either by condition or shape or anything.

    So at times I used this more like a vacuum cleaner.

    I also didn't use the bag. I followed the advice of other reviewers here and used my mower to clean up.

    A wise move.

    Mowing my front lawn typically fills my bin half way. After using this, and going over the lawn again with the mower, I nearly filled two bins.

    Maybe you won't have that problem. Maybe your lawn has been cared for properly. Mine hasn't.

    It's something to be aware of. Aside from the thought of emptying the dethatcher bag every 30 seconds, I've filled my green and trash bins, and that was with just my front yard. My back yard is over twice as big, so any more work of this nature is going to require trash bags or my neighbor's bins. If you have limited means of disposing or storing cut grass, you want to plan your lawn care schedule accordingly.

    Despite the instructions warning against going bagless, it worked fine. I didn't feel anything get thrown at me, but then I was wearing shoes and jeans. If you're doing your yard work in a Borat Mankini your mileage will vary...just please don't be my neighbor.

    One of the reasons I bought this over the other brands is the switch. The safety switch on the competition looked very awkward, and the reviews confirmed that. I'm not interested in awkward, and when it's too much of a hassle to operate the switch folks tend to leave the gear running rather than fight to turn it on again, which makes things LESS safe. It's like requiring a password that's so 'secure' and complex you pretty much have to write it down to remember it, making it less secure than requiring something simpler.

    This switch isn't terrible. In fact, I got used to it quickly, so I didn't have any problems.

    One huge pet peeve of mine is equipment that doesn't work for tall folks. I'm 6'4", and I can't tell you how many times I've had to stoop and slouch just to work with stuff designed for 'normal' people only. I was a little concerned about this.

    I didn't have to worry. No slouching or crouching was required. This makes me VERY happy!

    The height adjustment on this works wonderfully. It's simple, easy, and solid.

    Highly Recommend!
