Any body know of a leaf vac that is driven off the PTO of a small (25hp) tractor. I have 5 acres and mow about 3 of them. They get covered with leaves in the fall and want to pick them up and deposit them in the woods. I'm thinking of making something but need to get a blower/vac assembly---hopefully something that is off-the-shelf. There must be some company that makes a unit like this. Anybody know??????? Geo.
