Is Rack 'Em RCMMS4-EXS15 Grass Catcher Compatible with Chute Blocker on Exmark Viking Mower
Updated 08/21/2025 | Published 09/19/2019 >
Question:
I have a 2019 Exmark Viking hydro walk behind that has an Exmark manufactured operator controlled discharge chute blocker added as an option. I operate a commercial lawn care company. To use the grass catcher attachment would the OCD blocker have to be removed first?

According to Rack 'Em, the chute blocker would need to be removed to install the # RCMMS4-EXS15 grass catcher. I was told that it might be possible to make some modifications to the blocker or the grass catcher in order to get them to work together, but my Rack 'Em representative didn't have any specific details available as to how exactly this would be done.
I've linked you to a product description video featuring the # RCMMS4-EXS15 grass catcher.

Does the company make a chute blocker that will work interchangeably with the grass catcher? For example, I could slide the catcher off and then slide the chute blocker on the same mounting plate. I’m looking for something where I can switch between catching grass and blocking the chute with little effort. I have some customers that want their clippings picked up and others who have tight yards and I need the chute blocker. Thanks
