"I'm approaching 100 hours on briers, elm, hawthorne (ouch!!) hackberry, grape vines and leaves. Some tips: Be sure to have loppers handy because the feeder won't let crooked stuff go down too well. Don't dump too much into the leaf hopper at once, steady as she goes and you'll get it done fast.
I always find a forked stick, about 3 or 4 feet long, to help push briers and small branches down the hopper.
don't kill the engine while stuff is still in the hopper. You may not be able to pull the rope to crank it again and then you'll have to take the hopper off.
If you run it without the bag be ready for clouds of debris, this thing has a powerful blower.
This machine seems to handle everything it is designed for and is plenty sturdy for the job. Excellent value."
