I looked and looked for a lawn sweeper for a CUT a couple years ago and couldn't come up with anything either. I don't even care if it's PTO driven or wheel driven like the pull behinds for lawn tractors. I ended up getting a 42" pull behind (which was the biggest I could find) at Home Depot and use my Craftsman lawn tractor to clean up the parts of the yard that are real thick and just let the grass lay in the rest of the yard (my yard is 3 1/2 acres, so I don't have time to do it all). The pull behind wheel driven type work good and are fairly cheap (I only paid about $200 for mine on sale), so if someone would make one just like the one I have in a 6' width it would be great for a CUT, but no one makes them that big.
