One thing I've done this year is to use my leaf loader to load perennial grasses, hostas, and other plant material.
It actually works extremely well. The one material I've had issues with is Russian sage. Just fed it too fast and it clogged the hose a couple of times.
My loader is also set on the tongue of my trailer and the hose I's fairly flat to the ground, so ultimately I have a good path to the loader.
That and I also load all the plant debris with my hands to not overload the loader, along with not clogging the hose.
It really chopped up the material good, and goes to a local organic farm for composting.
