I had chipper/shredder very similar to that one when we first bought the house. It worked well though I had a few issues with it, like the discharge chute. Used it many years. Then got the lawn vacuum. I actually just bought the WORX shredder. Electric unit. very happy with it so far. Only used it twice, but so much better than the one I bought last season. Haven't had to replace the line yet. Does wet leaves fairly well, as well as anything else I've used except maybe a lawn mower. If the leaves were dry, I'm thinking I could easily go through a cubic yard in about 15 minutes.
