Anyone use a Gator on the bottom and an Exmark Mulching blade on the bottom? (or vise versa)? I have the DIRECTOR OCDC and can close off the discharge. Was thinking of trying this setup, but thought I would ask everyone their opinions. Of all the discussions about double blade setups, this combo was never mentioned. I have the blades but didn't get a chance to try it yet. This will be used on my new 27hp LC 60" Lazer.
