Looking for first hand knowledge for a grass and leaf collecter

[hillybilly]

I have a lawn sweep but I'm looking for something that can hold more product. Does anybody have any knowledge on this setup? Dry and damp leaves as well as dry and grass.
I would be mounting it on my TS 154X Husqvarna. It's equipped with A 27 hp Kawasaki if that matters.

What is manufacturer and model?
