Very rarely do we bag. Although the past two weeks we had to cause the freakin weather has been nuts. Anyhow, for those that "have to bag"... We had a customer that used to demand that we bagged the lawn. I keep informing that that it was healthier to mulch/discharge. Whatever, I guess they were old school. We took our mulching deck and mounted a side bag to it. The whole time we were mulching the homeowner thought we were bagging. They never complained again and we didn't bag again. You can argue about the ethics of it but we weren't charging extra to bag so I was okay with it.
