As stated in my other post, I have a Honda 21-inch mower right now. It can bag/mulch/discharge, with the discharge chute being on the side where they normally are. There is a spring loaded cover that is supposed to hold the chute down in place. The problem that I find is that when i go over either rough ground or a gravel driveway, the chute falls off from the vibrations. How do the units that use the side discharge chute out the rear (in place of the bagger) work? Some examples might be Toro, Exmark, Honda, John Deere, etc.
