Great aerator for the price
[This review was collected as part of a promotion.] We completed building our house in 2020 and I was having trouble growing grass. So I needed to aerate the yard so the grass seed would not wash away when it rained. After researching aerators I purchased this aerator because it was priced right and would be appropriate to pull behind my hydrostatic drive lawnmower. I was surprised at the strength of the frame for the light weight of the packaging that it came in. The instructions were easy to read and assembly was easy. I would suggest wearing gloves when assembling the spikes on the spike bar, the spikes are sharp. I found the weight tray on top of the aerator would easily fit three concrete blocks and there are round holes on the ends for a tie down that holds the concrete blocks in place. These concrete blocks give the aerator the extra weight it needs to really get into the dirt to do the job! If you are a homeowner and need an aerator, this is the one for you. It is light weight and easy to store, so you can save the rental fee for renting an aerator.

Easy to Assemble
My riding lawnmower used this very efficiently and I was able to strap on 2 cement blocks to add weight to it. It worked effortlessly but it was difficult making too tight a turn. The spike seemed to pierce the ground deep enough, about 2 inches. I'll have to wait to determine the impact it had by watching the sod grow.

Poor product
I have used this on my yard now 3 different times and each time I have to stop and bend back the spikes. Not very good quality

First, I'd like to thank all of the previous reviewer's for their comments. Based on what they said, I ordered the aerator, knowing that I'd have to modify it to make it usable in real life. So as soon as I got it, I added angle iron across the tray & down to the shaft ends, plus an enclosure for the weight tray (see attached pic - enclosure ends removed). After doing these mod's, I used it on my lawn w/ 100 lbs in the tray & it worked great - no issues w/ the structure bending. I also did away w/ the silly square plastic shaft bushings, as this was the next weak link. Anyway, the tines are nice & sharp & after these mod's, it did a great job.

    Not bad but
    Bought for the price and because it was convenient at the time. Easy to put together. Wished it would hold more weight. I maxed it at the 110 lbs and had to wait for a good rain for it to penetrate good, which it did. Having said that I noticed after first use the end panels bending out which caused tine bearings to start to separate, and I had made sure everything was tight before I used it. I fabricate, repair, and build things for a living so I know all was assembled properly. I added 1 L bracket to each end, (see pic) which upon second use held everything in place nice and tight, no separation of tine bearings. The brackets mounted in the holes that I used for the strap to hold blocks the first time. The brackets I mounted as it worked out, had another hole that actually made it easier to hook straps. So with a little re-engineering, it worked fine.

    OK. Excited. Assembly went well. Seems like strong steel and construction.  Fairly easy assembly.  Nice sharp spikes.  Bolted to my mower and off I go with a 100lb weight (close to max). Looking good.  Get to an elevation in the lawn and the side members that hold the weight off the spikes bends to 45 degrees.  The G-clip at the end of the rod that holds the spikes on falls off and it is gone.  Game over... Now.  I take unit apart.  Painstakenly bolt in angle brackets to these uprights, reapply the G-clips and I'm back in business.  An obvious flaw that could be fixed with a simple change.   Warranty probably no good now. Happy with product overall after changes.

      40 in. Tow-Behind Spike Aerator
      I bought this after reading some reviews. I figured for the price it was worth giving it a shot. Picked it up at my local Home Depot. Took it home and in 25 minutes had it together. Hooked it up to my riding mower and the thing worked great. Easy to put together. Easy to use. For the price it did a pretty good job on the yard. Worth the price if you want to aerate the lawn with out paying for a more expensive tool..
