I saw a vacuum system at a Toro dealer that utilizes single or dual Rubbermaid trash cans to collect the debris. It has a seperate engine and a vacuum head on top of the unit. That is a great idea. Take several cans with you and when one gets full, take it off and put on an empty one. With a regular bagger, you still have to dump it into cans or something. This way it's already bagged when it comes off the catcher. You can also use it to suck up piles that are already raked by pulling the hose off the mower. Does Exmark offer one of these systems and how much? The dealer told me the same unit would fit my Z. I would love to have the dual can unit.
