Steve, since removing and reinstalling the fixed blade from its holder normally requires a re-grind of the blade afterwards, due to distortion of the blade, this sounds as if you keep a special sole-plate to use with the groomer, and install them both as a set when you want to do a grooming job. The only alternative I can see is to keep a dedicated mower that is more or less permanently set up with the groomer installed. It that the way you see it too?
