I have a 1990 Toro 26624 21" mower. Got it fixed up and running like new but I am missing the bag and bag frame for it and I can't justify spending what they're asking for a new one to put on a free mower. Does anyone have a good recommendation for a mulching blade for this thing, i have a new blade in it that does an OK job but I'm wondering if there are better options. I do understand that these things are not the best mulchers because of the deck design.
