About 90% of my yard work requires removing debris and dumping it back in the compost pile. I have a trailer attachment for our trusty lawn mower that holds a lot, but I have two problems with it.
1. I can't back it up worth a damn, despite three years of practice. I jack-knife and end up hopping off the mower, picking up the trailer and setting it straight. Or, I completely remove the trailer from the mower and roll it back into the compost pile by hand.
2. I have to do just as much work to remove the debris from the trailer, as I did getting the leaves in there.
I'll hang onto my mower/wagon and love it because without it, I would be making 4x as many trips to the compost heap pushing a wheel barrow.
