The aerator came disassembled, but the instructions were well written and the parts fit together without any modifications. After about 2 hours of assembly, I loaded weights on the tray (I used bags of lead shot, but bricks or blocks would work as well) and started to work. I found that criss-crossing worked well, churning the bare spots enough for seeding but not damaging the existing lawn. Re-seeding and rolling went quickly after that.
I own a full machine shop, designed and performed much of the constructed on my current home, build custom firearms for a living, and restore muscle cars as a hobby; It took me 2+ hours to put this thing together. If all you have are the two 1/2 inch, two 9/16, and an adjustable wrench that the instructions call for to assemble it, and lack an elevated work bench; May God have mercy on your soul. The bolts are all 1? or longer with nylon lock nuts to hold thin gauge sheet metal together. Thankfully I had air tools to crank them down. Other than that it works pretty well, but then again ?How was the play Mrs. Lincoln.

I bought this and it was shipped to my house. It said some assembly required. But it should have said total assembly required. I had to put everything together. It took three hours by the time I had it adjusted up the my tractor and ready to start using. But after all of the hard work it works pretty good.
