I have a couple of fixed-deck Snappers I can never seem to get a good cut from. Over the years I have tried all kinds of blades and combinations, including doubles. They cut ok if you are only taking off a small amount of grass, but cant seem to be able to handle high grass. What happens is I get strips of uncut grass where the blades overlap, and clumps everywhere. I am running the blades up high inside the deck (no spacers) and was wondering if this is causing the problem. Instead of using the full 5 depth of the deck to process clippings, I am using only about 3. The problem is, if I lower the blades to use more deck, than Ill be cutting more grass off if its high a real catch 22. My decks are already attached at the highest point on the power units. I have to go over lawns 2-3 times just to get it cut, as opposed to 1 time with my Toro. Needless to say, the Toro is getting more use. Any input?
