Does not work on grass. Hoping to speed up grass collection for garden mulch but this attachment has no hope of being an assist. Mower cuts 6-12 in bahai and bermuda into non-chopped swaths with the stems fully intact. I have a home built hay rake with 3 in spacing on the tines that will roll the swaths into piles for transport to the garden. This attachment basically just spreads the swaths back out and burns diesel during it. Maybe it will work for leaves in the fall but I am not optimistic. Shipping was fast, packaging was acceptable and I own other Titan attachments which I can recommend without reservation. But not this one.
