This thing is an aluminum work of art! Very good design. Just lift it on and go, lift it off and dump into a 55 gal trash bag. The bag fits snugly on the back and 1 person can dump it with no problem. Full of mulched leaves and slightly wet grass, it felt like it weighed about 50 lbs full. Very wet grass would be heavier. No drilling, modification, or any attachments needed. The back door removes/re-attaches easily and instantly. It fills good if the grass is not too wet. If anyone is considering getting one, go as big as you can afford. This thing fills up very quickly w/ leaves or grass. I'm so glad I didn't get the small one. My 48" deck handles it great. It actually looks smaller in person than it does on the website. I think a 36" deck could even handle it fine. I almost thought they sent me the small one by mistake. The only complaint I have is the nearly $500 price tag, ouch. As long as I don't bang into any obstacles w/ it which I almost did already, I think it will last indefinitely.
