Haven't seen anyone post anything on this and I'm sure a lot of guys have wondered it. But why are homeowner and commercial unit mulching systems so different. With a homeowner rider, one can place a mulch plug over the grass chute, and 5 seconds later, you're ready to mulch. If you need to side discharge, bam, take the mulch plug out and 5 second later, you're ready. However... with a commercial rider, a Z, you must baffle each blade off and close the chute. Much much more time consuming. Why can't the manufactures make anything easy these days? Seems like the mulch plug over the chute would be a wise option for the commercial units as well, as I have seen some immaculant results with this method. Anyone else this annoys?
